PERIVASCULAR LYSATES AND USES THEREOF

BACKGROUND

Stem cell-based therapies have emerged as potential treatments for a variety of diseases and conditions, such as neurological conditions, inflammatory conditions, weight loss, and cancer. Studies evaluating such therapeutic approaches have typically used one of three treatment methodologies: 1) administration of intact stem cells, 2) administration of medium containing factors secreted by stem cells, or 3) administration of stem cell lysates. While these approaches have shown promise, they are limited in that they do not allow for treatment with the entire complement of proteins produced by stem cells, as the methodologies favor either secreted proteins or intracellular and transmembrane proteins.

Accordingly, there exists a need for improved stem cell compositions that contain all three types of proteins: intracellular, transmembrane, and secreted stem cell proteins.

SUMMARY OF THE INVENTION

The present invention provides compositions containing mesenchymal stem cell (MSC) proteins, such as human umbilical cord perivascular cell (HUCPVC) total protein products (HTPPs) that contain intracellular, transmembrane, and secreted HUCPVC proteins and methods of making and using such compositions. The compositions can be incorporated into pharmaceutical compositions, cosmetic compositions, and dermatologic compositions to treat autoimmune or inflammatory diseases or conditions, inflammation-related skin diseases and conditions, diseases or conditions characterized by local inflammation, skincare concerns, dermatological indications, and diseases or conditions characterized by a lack of angiogenesis or vascularization. The compositions can also be applied to cultured cells, such as cultured umbilical cord perivascular cells, to improve the health, proliferation, and longevity of the cells in culture.

As used herein, the term “pharmaceutically acceptable” refers to those compounds, materials, compositions and/or dosage forms, which are suitable for contact with the tissues of a subject, such as a mammal (e.g., a human) without excessive toxicity, irritation, allergic response and/or other problem complications commensurate with a reasonable benefit/risk ratio.

As used herein, the term “proliferation” refers to an increase in cell numbers through growth and division of cells.

As used herein, the terms “subject” and “patient” refer to an animal (e.g., a mammal, such as a human). A subject to be treated according to the methods described herein may be one who has a disease or condition associated with inflammation, or a skin condition, or one at risk of developing the disease or condition. Diagnosis may be performed by any method or technique known in the art. One skilled in the art will understand that a subject to be treated according to the present disclosure may have been subjected to standard tests or may have been identified, without examination, as one at risk due to the presence of one or more risk factors associated with the disease or condition.

As used herein, “treatment” and “treating” in reference to a disease or condition, refer to an approach for obtaining beneficial or desired results, e.g., clinical results. Beneficial or desired results can include, but are not limited to, alleviation or amelioration of one or more symptoms or conditions; diminishment of extent of disease or condition; stabilized (i.e., not worsening) state of disease, disorder, or condition; preventing spread of disease or condition; delay or slowing the progress of the disease or condition; amelioration or palliation of the disease or condition; and remission (whether partial or total), whether detectable or undetectable. “Ameliorating” or “palliating” a disease or condition means that the extent and/or undesirable clinical manifestations of the disease, disorder, or condition are lessened and/or time course of the progression is slowed or lengthened, as compared to the extent or time course in the absence of treatment. “Treatment” can also mean prolonging survival as compared to expected survival if not receiving treatment. Those in need of treatment include those already with the condition or disorder, as well as those prone to have the condition or disorder or those in which the condition or disorder is to be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a graph showing the effect of perivascular tissue lysate (PTL) on mouse hindpaw circumference in a model of inflammation. As shown in in FIG. 1, a significant reduction in hindpaw circumference was observed 48 hours after mice were treated with PTL (gray) and inflammatory agent carrageenan compared to mice treated with saline (control, black) and carrageenan. A decrease in paw circumference was also observed at the 24 hour time point.

FIG. 2 is a graph showing the effect of PTL on the expression of myeloperoxidase (MPO) in a model of inflammation. As shown in in FIG. 2, a marked decrease in MPO level was observed in in the injected paw of mice treated with PTL (gray) and inflammatory agent carrageenan compared to the MPO level in the injected paw of mice treated with saline (control, black) and carrageenan. A decrease in MPO is indicative of a reduction in neutrophil infiltration.

FIG. 3 is a graph showing the effect of PTL and human umbilical cord perivascular cell (HUCPVC) total protein product (HTPP) on pro-inflammatory cytokine tumor necrosis factor-alpha (TNFα) concentration in a model of inflammation. As shown in in FIG. 3, TNFα concentration was reduced in the injected paw of mice treated with PTL and inflammatory agent carrageenan compared to the TNFα concentration in the injected paw of mice treated with saline and carrageenan at four 4 hours (black) after injection. The TNFα concentration was further reduced in the injected paw of mice treated with PTL and carrageenan 24 hours (gray) after injection. The concentration of TNFα in the injected paw of mice treated with HTPP and carrageenan was lower at 24 hours after injection than the concentration of TNFα observed in the injected paw of mice treated with PTL and carrageenan.

DETAILED DESCRIPTION

Described herein are compositions containing umbilical cord perivascular cell proteins, such as umbilical cord perivascular cell total protein products (e.g., compositions that contain secreted, transmembrane, and intracellular proteins produced by cultured perivascular cells) or perivascular tissue lysates (e.g., lysates derived from intact perivascular Wharton's Jelly), or compositions containing proteins produced by cultured mesenchymal stem cells (MSCs), such as cultured MSC lysates or total protein products (e.g., lysates or total protein products derived from cultured umbilical cord perivascular stromal cells or other types of MSCs). These lysates and total protein products also contain other cellular components, such as cell membrane fragments and intracellular cellular structures. These compositions can be incorporated into pharmaceutical compositions, cosmetic compositions, and dermatological products to treat autoimmune or inflammatory diseases or conditions, inflammation-related skin diseases and conditions, diseases or conditions characterized by local inflammation, skincare concerns, dermatological indications, and diseases or conditions characterized by a lack of angiogenesis or a need for the formation of additional blood vessels. The compositions can also be applied to cultured cells, such as cultured umbilical cord perivascular cells, to improve the health and longevity of the cultured cells. The invention also features methods of producing the lysates or total protein products containing umbilical cord perivascular cell or MSC proteins.

Human Umbilical Cord Perivascular Cells (HUCPVCs)

Human umbilical cord perivascular cells (HUCPVCs) are a non-hematopoietic, mesenchymal, population of multipotent cells obtained from the perivascular region within the Wharton's Jelly of human umbilical cords (see, e.g., Sarugaser et al., “Human umbilical cord perivascular (HUCPV) cells: A source of mesenchymal progenitors,” Stem Cells 23:220-229 (2005)). U.S. Patent Application Publication 2005/0148074, U.S. Pat. No. 8,278,102, and International Patent Application Publication WO 2007/128115 describe methods for the isolation and culture of HUCPVCs and are incorporated by reference herein. HUCPVCs are further characterized by relatively rapid proliferation, exhibiting a doubling time, in each of passages 2-7, of about 20 hours (serum dependent) when cultured under standard adherent conditions. Phenotypically, the HUCPVCs are characterized, at harvest, as Oct 4−, CD14−, CD19−, CD34−, CD44+, CD45−, CD49e+, CD90+, CD105(SH2)+, CD73(SH3)+, CD79b−, HLA-G−, CXCR4+, and c-kit+. In addition, HUCPVCs are positive for CK8, CK18, CK19, PD-L2, CD146 and 3G5 (a pericyte marker), at levels higher relative to cell populations extracted from Wharton's Jelly sources other than the perivascular region.

The present disclosure is based, at least in part, on the discovery that total protein-containing products from mesenchymal stem cells, such as HUCPVCs (e.g., products that include intracellular and membrane-bound cellular proteins, as well as secreted proteins present in exosomes or vesicles that are secreted by the cell), have beneficial therapeutic properties. In particular, the total protein-containing products can be prepared using tissue from the perivascular region of vessels in Wharton's Jelly from the umbilical cord (e.g., the perivascular region containing HUCPVCs) or from cultured HUCPVCs. These products were found to contain over 600 proteins or protein fragments and to include small particles between about 20 to about 200 nanometers (nm) in size. In addition, incubation of HUCPVCs with saline was found to allow for the production of a more complete protein product containing secreted, intracellular, and transmembrane perivascular cell proteins. Unlike other connective tissues, Wharton's Jelly contains no blood vessels, nerves, lymph vessels, or other tissues. Therefore, perivascular tissue and stem cell-based products containing HUCPVC proteins and microparticles can be prepared from Wharton's jelly reasonably free from contamination from other cell or tissue types. These products also contain extracellular matrix (ECM) proteins produced by the HUCPVCs, which may contribute to or enhance their therapeutic effects. The perivascular tissue and stem cell products were found to exhibit anti-inflammatory properties in vivo, and to promote growth and longevity of cultured cells in vitro. These products were also enriched for therapeutic proteins compared to products (e.g., lysates) prepared from whole umbilical cord. While previous therapies have employed isolated HUCPVCs or supernatant derived from cultured HUCPVCs, the products of the present application contain both HUCPVC proteins and ECM proteins, and, in the case of total protein products, intracellular, transmembrane, and secreted HUCPVC proteins, which provide improved therapeutic benefits compared to cells or supernatant alone. Methods for preparing these products and uses for such products are described herein.

Compositions Containing Perivascular Tissue Lysates, MSC Total Protein Products, and/or MSC Lysates

Featured are total protein products that include intracellular, transmembrane, and secreted proteins from MSCs, such as HUCPVCs. These protein products, described as “total protein products” due to their inclusion of intracellular, transmembrane, and secreted proteins produced by MSCs (e.g., HUCPVCs), have a distinct advantage compared to standard stem cell-based compositions. Typical MSC-based compositions, including MSC conditioned medium, intact MSCs, and MSC lysates, fail to adequately capture at least one class of proteins. For example, MSC conditioned medium excludes transmembrane and intracellular MSC proteins, MSC lysates exclude secreted proteins, and intact MSCs communicate with their external environment using secreted and transmembrane proteins, failing to expose neighboring cells to intracellular proteins. The total protein products described herein are produced using methods that allow for the recovery of all three types of proteins due to the homogenization of the cells together with the materials (e.g., exosomes and vesicles) secreted by the cells, and accordingly, the total protein products include more protein, and may include a wider variety of proteins, than typical MSC-based compositions. Accordingly, the total protein products can be used to treat a variety of indications and have been found to exhibit beneficial results in both in vivo and in vitro applications.

Also featured are compositions containing perivascular tissue lysates (e.g., lysates derived from intact perivascular Wharton's Jelly) and/or MSC lysates (e.g., lysates derived from cultured HUCPVCs or other types of cultured MSCs). These lysates contain MSC proteins (e.g., HUCPVC proteins) and ECM proteins and exhibit therapeutic properties in vivo. We have discovered that perivascular tissue lysates contain nearly twice as many therapeutic proteins of interest as whole umbilical cord lysates and that compositions containing perivascular tissue lysates can both reduce inflammation and promote perivascular cell proliferation. Based on these findings, perivascular tissue lysates may also provide a number of therapeutic benefits, as is discussed below.

Production of Perivascular Total Protein Products

Perivascular total protein products (e.g., HUCPVC total protein products, or HTPPs) can be prepared using cultured perivascular stromal cells. Perivascular stromal cells can be isolated from the Wharton's Jelly attached to either fresh or frozen umbilical cord vessels (e.g., human umbilical cord vessels) as described herein below and expanded in culture. Methods of isolating HUCPVCs from fresh or frozen umbilical cord vessels are also described in, e.g., U.S. Pat. Nos. 7,547,546 and 8,278,102, incorporated herein by reference. Once in culture, the perivascular stromal cells can be passaged one or more times (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 times).

The perivascular stromal cells can be harvested after one or more passages and used to produce a total protein product (e.g., the cells can be harvested at passage 1 (P1), P2, P3, P4, P5, P6, P7, P8, P9, or P10, such as at P3). Perivascular stromal cells can be harvested by aspirating the spent medium from the cultured cells, trypsinizing the cells (e.g., adding a trypsin-containing product to the cells, such as about 10 to about 15 mL of TrypLE, and incubating the cells for about 5 to about 10 minutes (e.g., 10 minutes) at about 35° C. to about 37° C.). Once the cells have completely detached from the culture vessel (e.g., a flask or plate), they can be flushed from the vessel using complete medium and a pipette (e.g., about 10 to about 15 mL of complete medium, such as 12 mL of complete medium) and transferred to a 50 mL tube. Next, the cells can be centrifuged to create a pellet (e.g., at about 290×g at about 4° C. for about 10 minutes) followed by resuspension and cell counting (e.g., using a hemocytometer or ViCell). Once cell counts have been determined, the perivascular stromal cells can be seeded for further expansion (e.g., at about 2000 cells/cm²), cryopreserved for future use, or used to produce a total protein product.

Whether cells are to be cryopreserved or immediately used to produce a total protein product, they are first centrifuged to create a pellet (e.g., at about 290×g at about 4° C. for about 10 minutes). The perivascular stromal cells can then be resuspended in an appropriate solution. If the perivascular stromal cells are to be used immediately to produce a total protein product, they are resuspended in saline (e.g., about 0.5 mL to about 1.5 mL saline, such as 1 mL saline) and counted (e.g., using a hemocytometer or ViCell and a 1:10 dilution). Alternatively, if cryopreserved perivascular cells used to produce the total protein product, they can first be thawed until a small sliver of ice remains (e.g., in an about 30° C. to about 37° C. water bath for about 2 minutes). Complete medium can then be added dropwise to the vial containing the cells (e.g., about 1 mL), and after a two-minute waiting period at room temperature, the contents of the vial can be transferred to a 15 mL tube and additional complete medium can be added to the 15 mL tube (e.g., about 2 mL). After another wait at room temperature (e.g., about five minutes), the perivascular stromal cells can be centrifuged to create a pellet (e.g., at about 290×g at about 4° C. for about 10 minutes), resuspended in saline (e.g., about 0.5 mL to about 1.5 mL saline, such as 1 mL saline), and counted (e.g., using a hemocytometer or ViCell and a 1:10 dilution).

The perivascular cells are then incubated in the saline (0.9% sodium chloride in sterile water) at about 37° C. for about 15 minutes to about 24 hours (e.g., 15 minutes, 30 minutes, 45 minutes, or 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours, e.g., about 3 to about 8 hours, about 4 to about 7 hours, or about 6 hours). Without wishing to be bound by theory, incubating the perivascular cells in saline for a period of hours allows the cells to release secreted proteins (e.g., in exosomes and/or vesicles). Following the incubation in saline, the cells remain in the saline with the secreted proteins (e.g., the exosomes and/or vesicles) and are homogenized (e.g., using four rounds of 30 seconds of homogenization, e.g., bead mill-based homogenization, with 1-minute intervals on ice). After homogenizing the cells, saline is added for a final concentration of approximately 1 million cells (corresponding to 1 million cell equivalents) per mL. The supernatant is then filter sterilized (e.g., using a syringe filter, such as an about 0.2 μm to an about 0.45 μm syringe filter, such as a 0.22 μm syringe filter, or a vacuum filter), and it is the sterilized material that constitutes the total protein product. The total protein product can be used immediately or aliquoted (e.g., in 5 μL, 10 μL, 20 μL, 25 μL, 50 μL, 100 μL, 250 μL, 500 μL, 750 μL, 1 mL, 1.5 mL, 2 mL, 2.5 mL, 5 mL, or 10 mL aliquots) and frozen (e.g., stored at a temperature of −80° C. or lower, e.g., at −80° C., −120° C., or −140° C.) for later use. The HTPP contains all three classes of proteins: intracellular, transmembrane, and secreted (e.g., proteins contained in the exosomes and/or vesicles) in addition to other cellular components, such as cell membrane fragments and intracellular structures.

In an alternative methodology, HTPP can be produced without culturing. In this method, HUCPVCs are collected directly from the perivascular tissue attached to the umbilical cord vessels and homogenized with exosomes and/or vesicles in a small volume (e.g., to produce a homogenized solution having at least 500,000 cell equivalents, such as about 500,000 cell equivalents to about 2 million cell equivalents in a volume of 2 mL or less, such as in a volume of 2 mL, 1.5 mL, 1 mL or 0.5 mL). The resulting homogenate is a HTPP containing all three classes of proteins: intracellular, transmembrane, and secreted (e.g., proteins contained in the exosomes and/or vesicles). The HTPP also contains other cellular components, such as cell membrane fragments and intracellular structures.

Production of Perivascular Tissue Lysate

Perivascular tissue lysate can be prepared using fresh or frozen human umbilical cord vessels (e.g., arteries and/or veins). If frozen umbilical cord vessels are used to produce perivascular tissue lysate, the lysate can be produced once the vessels are thawed. Perivascular tissue lysates can also be prepared using umbilical cord vessels from other placental mammals.

An exemplary method for producing perivascular tissue lysate from frozen human umbilical cord vessels includes a first step of thawing (e.g., in an about 30° C. to about 37° C. water bath for about 15 to 20 minutes) frozen human umbilical cord vessels (e.g., one 15 mL cryopod containing 2 arteries and 1 vein for each donor lot). Next, the vessels are transferred to a specimen container and rinsed with phosphate buffered saline (PBS, e.g., 100 to 250 mL PBS), which may be performed by adding PBS to the container, sealing the container (e.g., with a cap), and shaking the container to rinse out blood. The vessels can be rinsed an additional one or more times (e.g., 1, 2, 3, 4, or more additional rinses, e.g., once more for a total of two rinse steps) by transferring the vessels to a fresh specimen container and repeating the rinse step. Once the vessels have been rinsed, Wharton's jelly (WJ) can be removed by placing the vessels on a surface (e.g., a silicone mat) and stripping the WJ (e.g., using forceps). Any WJ that is contaminated by blood can be cut off and discarded, leaving strips of WJ that are free from blood contamination. The WJ strips can then be cut into small pieces (e.g., 0.5 cm to 2.0 cm in length), transferred to a specimen container, and weighed. Next, the WJ tissue can be transferred to a container for homogenization or blending (e.g., for manual homogenization, such as using a mortar and pestle, or for homogenization or blending using a machine, such as bead-based or blender-based homogenization). For example, the WJ tissue can be transferred to a blender cup (e.g., a Baby Bullet blender cup). The specimen container previously holding the WJ can then be rinsed with saline (e.g., about 5 mL to about 10 mL saline), which can then be collected and added to the container for homogenization or blending (e.g., the blender cup). Frozen saline can then be added to the container for homogenization or blending (e.g., the blender cup) to achieve a final tissue weight (g): volume of saline (mL) ratio of about 1:3. If the perivascular tissue lysate is to be used for an in vitro application (e.g., added to cultured cells), basal medium can be used instead of saline. The tissue can then be homogenized or blended (e.g., blended continuously for about 2 minutes in the Baby Bullet blender, or until the tissue is fully blended or homogenized), and the homogenized or blended material can be transferred to two fresh tubes for centrifugation in a refrigerated centrifuge (e.g., to two 15 or 50 mL tubes for centrifugation at about 500×g for about 15 to 20 minutes at about 4° C.). After centrifugation, the supernatant can be collected and pooled in a collection tube. The centrifugation and supernatant collection steps can then be repeated, with all of the collected supernatant added to the single collection tube. Next, the pellets can be spun at a higher speed in a refrigerated centrifuge (e.g., at about 3716×g for about 15 to 20 minutes at about 4° C.) and the resulting supernatant can be collected and added to the single collection tube. The pellets can be spun and the supernatant collected until there is no more supernatant separation. Once all of the supernatant has been collected, the single collection tube can be spun in the refrigerated centrifuge (e.g., at about 500×g for about 15 to 20 minutes at about 4° C.). After centrifugation, the supernatant from the collection tube can be collected and sterilized by filtration (e.g., through a 0.22 μM filter, such as a syringe filter or a vacuum filtration system). The resulting material is the perivascular tissue lysate, which can be used immediately or aliquoted (e.g., in 5 μL, 10 μL, 20 μL, 25 μL, 50 μL, 100 μL, 250 μL, 500 μL, 750 μL, 1 mL, 1.5 mL, 2 mL, 2.5 mL, 5 mL, or 10 mL aliquots) and frozen (e.g., stored at a temperature of −80° C. or lower, e.g., at −80° C., −120° C., or −140° C.) for later use.

Production of Perivascular Stem Cell Lysate

Lysate can also be prepared from cultured human umbilical cord perivascular stromal cells (HUCPVCs). HUCPVCs can be isolated from fresh or frozen human umbilical cord using established methods, such as those described in, e.g., U.S. Pat. Nos. 7,547,546 and 8,278,102, incorporated herein by reference, and subsequently cultured and expanded as described herein. Once the cells have passaged one or more times (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 times), they can be harvested and used to generate a lysate (e.g., the cells can be harvested at passage 1 (P1), P2, P3, P4, P5, P6, P7, P8, P9, or P10, such as at P3).

Three different approaches that can be used to produce perivascular stem cell lysate are described herein.

In a first approach, expanded HUCPVCs can be harvested with trypsinization to produce a cell lysate. First, spent culture medium can be aspirated, then a pre-warmed trypsin-containing solution (e.g., TrypLE Express Enzyme) can be added to the HUCPVC culture e.g., (about 2 mL to about 10 mL per 75 cm², e.g., about 4 mL) and the cells can be incubated at about 37° C. for about 5 minutes to about 10 minutes. Next, the vessel (e.g., plate, dish, or flask) containing the HUCPVCs can be tapped gently to detach the cells and complete cell detachment can be confirmed visually using a microscope. Complete medium can then be added to the culture vessel and the HUCPVCs can be flushed off of the cell culture surface (e.g., a pipette can be used to flush the cells off the surface using the medium). The resulting cell suspension can be added to a collection tube and a cell count can be performed (e.g., using a hemocytometer and Trypan Blue) to determine the number of viable cells. The cells can then be spun in a refrigerated centrifuge at about 200×g to about 400×g, e.g., at 290×g for about 10 to about 15 minutes at 4° C. After centrifugation, the supernatant can be aspirated and the cells can be lysed, for example, using methods known in the art. Two methods for cell lysis are described:

Method 1: Perform 3 freeze-thaw cycles by freezing the cells at −20° C. or lower (e.g., −20° C., −25° C., −30° C., −35° C., −40° C., or lower) and thawing the cells at about 25° C. to about 37° C., then re-suspend in saline solution to about one million cells per mL.

Method 2: Re-suspend cells in saline solution to about one million cells per mL and homogenize (e.g., using a manual homogenizer or a bead homogenizer) for three 30 to 45 second rounds with a one to two-minute interval on ice.

In a second approach, expanded HUCPVCs can be harvested without trypsinization (e.g., using mechanical force to separate the cells from the vessel) to produce a cell lysate. First, spent culture medium can be aspirated, then the vessel (e.g., plate, dish, or flask) containing the HUCPVCs can be rinsed twice with PBS (about 5 mL to about 10 mL, e.g., about 8 mL per 75 cm²). Next, saline solution can be added to the vessel (about 2 mL to about 12 mL, e.g., about 4 mL per 75 cm²) and the cells can be detached from the vessel using mechanical force (e.g., using a cell scraper). Complete cell detachment can be confirmed visually using a microscope. The cell suspension can then be added to a collection tube and the cells can be lysed, for example, using methods known in the art. Two methods for cell lysis are described:

In a third approach, the cell lysate can be prepared from HUCPVCs that have been cryopreserved (e.g., as described in U.S. Pat. Nos. 7,547,546, 8,277,794, and 8,790,923). First, a vial of cells (e.g., a 1 mL vial) can be removed from liquid nitrogen and placed in a warm water bath (e.g., a water bath between about 33° C. and about 40° C., e.g., about 37° C.). The vial of cells can be thawed until a small sliver of ice remains (about 1-3 minutes, e.g., about 2 minutes) and then transferred to a biosafety cabinet. Next, about 1 mL of pre-warmed basal medium can be added dropwise to the vial of cells and incubated for about 1-5 min, e.g., about 2 min at room temperature (e.g., about 22° C. to about 27° C.). The content of the vial (now about 2 mL) can then be transferred to a 15 mL tube and enough basal medium can be quickly added to the tube to double the volume of medium in the tube (e.g., about 2 mL is added for a total of about 4 mL). The vial can be incubated at room temperature (e.g., about 22° C. to about 27° C.) for about 5 to 10 minutes, e.g., about 5 minutes, and then, optionally, a cell count can be performed (e.g., using a hemocytometer and Trypan Blue) to determine the number of viable cells. The cells can then be spun in a refrigerated centrifuge at about 200×g to about 400×g, e.g., at about 290×g, for about 10 to about 15 minutes at 4° C. After centrifugation, the supernatant can be aspirated and the cells can be lysed, for example, using methods known in the art. Two methods for cell lysis are described.

After the cells are lysed (e.g., using an approach such as those described above), the cell suspension can be spun at about 200×g to about 400×g, e.g., at about 290×g for about 10 to 20 minutes, e.g., about 15 minutes in a refrigerated centrifuge (e.g., at about 4° C.). After centrifugation, the supernatant can be collected and sterilized (e.g., through a 0.22 μM filter, such as a syringe filter or a vacuum filtration system). The resulting material is the perivascular stem cell lysate, which can be used immediately or aliquoted (e.g., in 5 μL, 10 μL, 20 μL, 25 μL, 50 μL, 100 μL, 250 μL, 500 μL, 750 μL, 1 mL, 1.5 mL, 2 mL, 2.5 mL, 5 mL, or 10 mL aliquots) and frozen (e.g., stored at a temperature of −80° C. or lower, e.g., at −80° C., −120° C., or −140° C.) for later use.

Production of Total Protein Products and Lysates from Other Types of Mesenchymal Stem Cells

In some embodiments, total protein products and/or lysates may be prepared from cultured MSCs other than HUCPVCs. Although other MSC-containing tissues (e.g., adipose tissue, bone marrow, dental tissue) may not be amenable to production of a tissue lysate due to the presence of non-MSCs in the tissue, isolated, cultured MSCs from these tissues can be used to prepare total protein products and/or cell lysates according to the methods described above. Tissues from which MSCs can be isolated and cultured for production of total protein products and/or cell lysates include bone marrow, adipose tissue, amniotic fluid, amniotic membrane, dental tissue, endometrium, limb bud, menstrual blood, peripheral blood, umbilical cord blood, placenta and fetal membrane, embryonic yolk sac, salivary gland, skin and foreskin, synovial fluid, and sub-amniotic umbilical cord lining membrane.

Uses of Perivascular Tissue Lysates, MSC Total Protein Products, and/or MSC Lysates

The MSC total protein products (e.g., HTPPs), perivascular tissue lysates, and/or MSC lysates (e.g., HUCPVC lysates) described herein can be used in a variety of applications. Perivascular tissue lysates were found to contain a large number of immune-related proteins (e.g., anti-inflammatory proteins and proteins that modulate the immune response) and were also found to reduce inflammation in vivo. Accordingly, MSC total protein products (e.g., HTPPs), perivascular stem cell lysates, and/or MSC lysates (e.g., HUCPVC lysates) or compositions including the lysates or total protein products can be used to treat autoimmune or inflammatory diseases or conditions and/or local inflammation. In addition, many of the proteins identified in the perivascular tissue lysates would be useful in skincare applications (e.g., anti-inflammatory proteins, angiogenic proteins, proteins that modulate the immune response, antioxidant proteins, and anti-aging proteins), indicating that MSC total protein products (e.g., HTPPs), perivascular stem cell lysates, and/or MSC lysates (e.g., HUCPVC lysates) may also be used for cosmetic and dermatological treatments. In addition, the lysates and total protein products have been found to promote beneficial effects on cell growth and longevity in culture, demonstrating their utility as cell culture reagents.

Use of Perivascular Tissue Lysates, MSC Total Protein Products, and/or MSC Lysates to Treat or Reduce Inflammation

Treatment of Autoimmune or Inflammatory Diseases or Conditions

The perivascular tissue lysates, MSC total protein products (e.g., HTPPs), and/or MSC (e.g., HUCPVC) lysates described herein can be used to treat an autoimmune or inflammatory disease or condition in a subject in need thereof by administering an effective amount of the lysate or total protein product, or a pharmaceutical composition containing the lysate or total protein product, to the subject. The method can include administering the perivascular tissue lysate, MSC total protein product (e.g., HTPP), and/or MSC (e.g., HUCPVC) lysate, or a pharmaceutical composition containing a lysate or total protein product described herein, locally (e.g., topically, by local injection, or by inhalation, e.g., inhalation into the lungs via nebulization or an aerosol) or systemically to the subject in a dose (e.g., effective amount) and for a time sufficient to treat the autoimmune or inflammatory disease or condition.

Treatment of Local Inflammation

The perivascular tissue lysates, MSC total protein products (e.g., HTPPs), and/or MSC (e.g., HUCPVC) lysates described herein can also be formulated for injection to treat local inflammation. The lysates, total protein products, or pharmaceutical compositions containing the lysates or total protein products can be injected into or near a region of the body that is inflamed to reduce inflammation, pain, or swelling, or to prevent inflammation, swelling, or pain from worsening. Conditions for which local injection of a perivascular tissue lysate, MSC total protein product (e.g., HTPP), and/or an MSC (e.g., HUCPVC) lysate or a pharmaceutical composition containing such a lysate or total protein product can be used for treatment include, e.g., inflammation of a bursa (e.g., bursitis of the hip, knee, elbow, or shoulder), inflammation of a tendon (e.g., tendinitis, such as tennis elbow), inflammation of a joint (e.g., arthritis, such as osteoarthritis, rheumatoid arthritis, reactive arthritis, or psoriatic arthritis), inflammation of the jaw (e.g., as in temporomandibular joint (TMJ) disorders), inflammation of a gland (e.g., a salivary gland, such as in Sjogren's syndrome), back pain, neck pain, sciatica, trigger finger, carpal tunnel syndrome and other entrapment syndromes, synovitis, rotator cuff syndrome, impingement syndrome, alopecia, frozen shoulder syndrome, fasciitis, and gout. Perivascular tissue lysates, MSC total protein products (e.g., HTPPs), and/or MSC (e.g., HUCPVC) lysates or pharmaceutical compositions containing the lysates or total protein products may be given by intra-articular injection (e.g., into a joint), intramuscular injection (e.g., into a muscle), epidural injection (e.g., into the spine), or local injection to or near a region of inflammation. Perivascular tissue lysates, MSC total protein products (e.g., HTPPs), and/or MSC (e.g., HUCPVC) lysates or pharmaceutical compositions containing the lysates or total protein products may also be administered by inhalation (e.g., by nebulization or using an aerosol formulation) to treat lung inflammation.

The perivascular tissue lysates, MSC total protein products (e.g., HTPPs), and/or MSC (e.g., HUCPVC) lysates can also be used to increase or promote angiogenesis (e.g., vascularization). Accordingly, the lysates or total protein products described herein can be injected into regions of the body in need of additional blood flow or to treat subjects that may benefit from increased blood flow, such as subjects suffering from a cardiovascular disease, such as ischemia (e.g., to stimulate the growth of new vessels in ischemic tissue), subjects at risk of losing a limb, subjects who have received a tissue transplant (e.g., to promote vascularization in the tissue transplant), subjects having abnormal or poor vasculature, or subjects having a wound (e.g., for promoting wound healing).

The autoimmune or inflammatory diseases or conditions described above and the angiogenesis-related diseases or conditions described above can be treated with lysates produced from perivascular tissue and/or MSCs (e.g., HUCPVCs) or with MSC total protein products (e.g., HTPPs) prepared using MSCs. The lysates or protein products may be administered directly to a subject or formulated with a pharmaceutically acceptable carrier or excipient. The lysates or total protein products may also be formulated with other anti-inflammatory or immunosuppressive agents, or the lysates, total protein products, or lysate- or total protein product-containing pharmaceutical compositions may be administered in combination with other agents or medications used to treat the autoimmune, inflammatory, or angiogenesis-related disease or condition.

The lysates, total protein products, and compositions described herein may be administered to a subject in need thereof (e.g., a subject having a disease or condition described herein, e.g., an autoimmune or inflammatory disease or condition or an angiogenesis-related disease or condition) by a variety of routes, such as local administration to the site affected by the disease or condition (e.g., local administration to or near the site of inflammation or reduced angiogenesis, such as injection to a joint for treating arthritis (e.g., RA, psoriatic arthritis, osteoarthritis, or reactive arthritis), injection into the spine for treating sciatica, injection into an ischemic tissue for treating a subject having ischemia, or topical administration to a region affected by an inflammation-related skin disease or condition), intravenous, parenteral, intradermal, transdermal, intramuscular, intranasal, subcutaneous, percutaneous, intratracheal, intraperitoneal, intraarterial, intravascular, intrathecal, intra-articular, epidural, inhalation, perfusion, lavage, and oral administration. For topical administration, the lysates, total protein products, or compositions may be formulated as a cream, ointment, lotion, gel, suspension, emulsion, or spray. For inhalation, the lysates, total protein products, or compositions may be formulated as an aerosol or formulated for nebulization. The most suitable route for administration in any given case will depend on the particular disease or condition being treated, the particular composition administered, the patient, pharmaceutical formulation methods, administration methods (e.g., administration time and administration route), the patient's age, body weight, sex, severity of the disease being treated, the patient's diet, and the patient's excretion rate. Compositions may be administered once, or more than once (e.g., once annually, twice annually, three times annually, bi-monthly, monthly, weekly, daily, or twice a day). For local administration, the lysates, total protein products, and compositions may be administered topically, by injection, or by inhalation (e.g., to treat an autoimmune, inflammatory, or angiogenesis-related disease or condition).

Subjects that may be treated as described herein are subjects having a disease or condition described herein (e.g., an autoimmune or inflammatory disease or condition, an inflammation-related skin disease or condition, bursitis of the hip, knee, elbow, or shoulder; tendon inflammation, e.g., tendinitis, such as tennis elbow; joint inflammation, e.g., arthritis, such as osteoarthritis, rheumatoid arthritis, reactive arthritis, or psoriatic arthritis; jaw inflammation, e.g., TMJ disease; inflammation of a gland, e.g., a salivary gland, such as in Sjogren's syndrome; back pain; neck pain; sciatica; trigger finger; carpal tunnel syndrome and other entrapment syndromes; synovitis; rotator cuff syndrome; impingement syndrome; alopecia (e.g., alopecia areata); frozen shoulder syndrome; fasciitis; gout; or an angiogenesis-related disease or condition (e.g., a cardiovascular disease, such as ischemia, risk of loss of a limb, tissue transplant, abnormal or poor vasculature, or a wound (e.g., for promoting wound healing)). The lysates, total protein products, compositions, and methods described herein can be used to treat a disease or condition caused by or associated with autoimmunity, inflammation, or a lack of blood vessels or need for vascularization. The methods described herein may also include a step of evaluating the symptoms of the disease or condition in a subject prior to treatment with or administration of the lysates, total protein products, or compositions described herein. The subject can then be evaluated using the same diagnostic tests after administration of the lysates, total protein products, or compositions to determine whether the subject's condition has improved.

Treatment may include administration of a lysate, total protein product, or a composition containing a lysate in various unit doses. Each unit dose will ordinarily contain a predetermined quantity of a lysate or total protein product described herein. The quantity to be administered, and the particular route of administration and formulation are within the skill of those in the clinical arts. A unit dose need not be administered as a single injection but may comprise continuous infusion over a set period of time. Dosing may be performed using a syringe. The amount of lysate, total protein product, or composition administered may vary depending on the size of the affected area (e.g., the region of the body afflicted with inflammation or a lack of blood vessels). The lysate, total protein product, or lysate- or total protein product-containing composition can be administered in a therapeutically effective amount, such as from 10 μg/kg to 500 mg/kg (e.g., 10 μg/kg, 100 μg/kg, 500 μg/kg, 1 mg/kg, 10 mg/kg, 50 mg/kg, 100 mg/kg, 250 mg/kg, or 500 mg/kg). Lysates, total protein products, or compositions can be administered in two or more doses (e.g., two, three, four, five, or more different doses) or at the same dose two or more times (e.g., two, three, four, five, six, or more times over the course of an hour, day, week, month, or year). The lysates or total protein products may also be diluted prior to administration or formulation in a composition (e.g., diluted by 1:2, 1:5, 1:10, 1:20, 1:50, 1:100, 1:250, or more).

The lysates, total protein products, and compositions described herein are administered in an amount sufficient to reduce inflammation, reduce pain, swelling, and/or stiffness associated with inflammation or an autoimmune or inflammatory disease or condition (e.g., joint pain or stiffness associated with scleroderma or arthritis, such as rheumatoid arthritis), increase or induce angiogenesis (e.g., increase the number or extent of blood vessels in a tissue), or treat a disease or condition described herein (e.g., an autoimmune or inflammatory disease or condition, an inflammation-related skin disease or condition, bursitis of the hip, knee, elbow, or shoulder; tendon inflammation, e.g., tendinitis, such as tennis elbow; joint inflammation, e.g., arthritis, such as osteoarthritis, rheumatoid arthritis, reactive arthritis, or psoriatic arthritis; jaw inflammation, e.g., TMJ; inflammation of a gland, e.g., a salivary gland, such as in Sjogren's syndrome; back pain; neck pain; sciatica; trigger finger; carpal tunnel syndrome and other entrapment syndromes; synovitis; rotator cuff syndrome; impingement syndrome; alopecia (e.g., alopecia areata); frozen shoulder syndrome; fasciitis; gout; or an angiogenesis-related disease or condition (e.g., a cardiovascular disease, such as ischemia, risk of losing a limb, tissue transplant, abnormal or poor vasculature, or a wound (e.g., for promoting wound healing)). Inflammation, symptoms of inflammation or an autoimmune disease (e.g., pain, swelling, stiffness, cytokine levels, and/or auto-antibody levels), angiogenesis (e.g., vascularization), and the condition of the skin can be evaluated using standard methods known by those of skill in the art and may be improved after administration of the lysates, total protein products, or compositions described herein compared to inflammation, symptoms of inflammation (e.g., pain, swelling, stiffness, cytokine levels, and/or autoantibody levels), angiogenesis (e.g., vascularization), and the condition of the skin prior to treatment or compared to untreated subjects with the same disease or condition. Symptoms of diseases and conditions described herein can be evaluated using standard methods known to those of skill in the art and may be reduced (e.g., the subject's condition may be improved) after administration of the lysates, total protein products, or compositions described herein compared to symptoms prior to administration of the lysates, total protein products, or compositions described herein or compared to untreated subjects with the same disease or condition. These effects may occur, for example, within 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, 8 weeks, 9 weeks, 10 weeks, 15 weeks, 20 weeks, 25 weeks, or more, following administration of the compositions described herein. The patient may be evaluated 1 month, 2 months, 3 months, 4 months, 5 months, 6 months or more following administration of the lysate, total protein product, or composition depending on the dose and route of administration used for treatment. Depending on the outcome of the evaluation, the patient may receive additional treatments.

Use of Perivascular Tissue Lysates, MSC Total Protein Products, and/or MSC Lysates for Skincare

Pharmaceutical Compositions

The lysates and/or or total protein products described herein may be incorporated into a composition containing a vehicle or excipient for administration to a patient, such as a human patient suffering from an autoimmune or inflammatory disease or condition, an inflammation-related skin disease or condition, local inflammation, or an angiogenesis-related disease or condition described herein. Pharmaceutical compositions containing lysates and/or total protein products can be prepared using methods known in the art. For example, such compositions can be prepared using, e.g., physiologically acceptable carriers, excipients or stabilizers (Remington: The Science and Practice of Pharmacology 22nd edition, Allen, L. Ed. (2013); incorporated herein by reference), and in a desired form, e.g., in the form of aqueous solutions, e.g., solutions that can be formulated for injection, inhalation (e.g., nebulization or delivery as an aerosol), or topical administration.

The lysates and/or or total protein products described herein can be administered in any physiologically compatible carrier, such as a buffered saline solution. Pharmaceutically acceptable carriers and diluents include saline, aqueous buffer solutions, solvents and/or dispersion media. The use of such carriers and diluents is well known in the art. Other examples include liquid media, for example, Dulbecco's modified eagle's medium (DMEM), sterile saline, sterile phosphate buffered saline, Leibovitz's medium (L15, Invitrogen, Carlsbad, Calif.), dextrose in sterile water, and any other physiologically acceptable liquid.

The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol, and the like), suitable mixtures thereof, and/or vegetable oils. Proper fluidity may be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. In many cases, it will be preferable to include isotonic agents, for example, sugars or sodium chloride. The solution is preferably sterile and fluid to the extent that easy syringability exists. Preferably, the solution is stable under the conditions of manufacture and storage and preserved against the contaminating action of microorganisms such as bacteria and fungi through the use of, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosol, and the like. Solutions of the invention can be prepared by using a pharmaceutically acceptable carrier or diluent and, as required, other ingredients enumerated above, followed by filtered sterilization, and then incorporating the cloaked cells as described herein.

For example, a solution containing a pharmaceutical composition described herein may be suitably buffered, if necessary, and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous, and intraperitoneal administration. In this connection, sterile aqueous media that can be employed will be known to those of skill in the art in light of the present disclosure. The person responsible for administration will, in any event, determine the appropriate dose for the individual subject. Moreover, for human administration, preparations may meet sterility, pyrogenicity, general safety, and purity standards as required by FDA Office of Biologics standards.

Deodorizing Active Ingredients

As deodorizing active ingredients there come into consideration, for example, antiperspirants, for example aluminum chlorohydrates (see J. Soc. Cosm. Chem. 24:281, 1973). Under the trade mark Locron® of Hoechst AG, Frankfurt (FRG), there is available commercially, for example, an aluminium chlorohydrate corresponding to formula Al₂(OH)₅Cl×2.5H₂O, the use of which is especially preferred (see J. Pharm. Pharmacol. 26:531, 1975). Besides the chlorohydrates, it is also possible to use aluminium hydroxyacetates and acidic aluminium/zirconium salts. Esterase inhibitors may be added as further deodorizing active ingredients. Such inhibitors are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and especially triethyl citrate (Hydagen CAT, Henkel), which inhibit enzyme activity and hence reduce odor formation. Further substances that come into consideration as esterase inhibitors are sterol sulfates or phosphates, for example lanosterol, cholesterol, campesterol, stigmasterol, and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid and malonic acid diethyl ester, and hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester. Antibacterial active ingredients that influence the germ flora and kill or inhibit the growth of sweat-decomposing bacteria can likewise be present in the preparations (especially in stick preparations). Examples include chitosan, phenoxyethanol and chlorhexidine gluconate. 5-chloro-2-(2,4-dichlorophenoxy)-phenol (Triclosan, Irgasan, Ciba Specialty Chemicals Inc.) has also proved especially effective.

Typical examples of such antioxidants are amino acids (e.g. glycine, histidine, tyrosine, tryptophan) and derivatives thereof, imidazoles (e.g. urocanic acid) and derivatives thereof, peptides, such as D,L-carnosine, D-carnosine, L-carnosine and derivatives thereof (e.g. anserine), carotinoids, carotenes, lycopene and derivatives thereof, chlorogenic acid and derivatives thereof, lipoic acid and derivatives thereof (e.g. dihydrolipoic acid), aurothioglycose, propylthiouracil and other thiols (e.g. thioredoxin, glutathione, cysteine, cystine, cystamine and the glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl, lauryl, palmitoyl, oleyl, linoleyl, cholesteryl and glyceryl esters thereof) and also salts thereof, dilauryl thiodipropionate, distearyl thiodipropionate, thiodipropionic acid and derivatives thereof (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts) and also sulfoximine compounds (e.g. buthionine sulfoximines, homocysteine sulfoximine, buthionine sulfones, penta-, hexa-, hepta-thionine sulfoximine), also (metal) chelating agents (e.g. hydroxy fatty acids, palmitic acid, phytic acid, lactoferrin), hydroxy acids (e.g. citric acid, lactic acid, malic acid), humic acid, bile acid, bile extracts, bilirubin, biliverdin, EDTA, EDDS, EGTA and derivatives thereof, unsaturated fatty acids and derivatives thereof (e.g. linolenic acid, linoleic acid, oleic acid), folic acid and derivatives thereof, ubiquinone and ubiquinol and derivatives thereof, vitamin C and derivatives (e.g. ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbyl acetate), tocopherols and derivatives (e.g. vitamin E acetate), vitamin A and derivatives (e.g. vitamin A palmitate) and also coniferyl benzoate of benzoin resin, rutinic acid and derivatives thereof, glycosylrutin, ferulic acid, furfurylidene glucitol, carnosine, butyl hydroxytoluene, butyl hydroxyanisole, nordihydroguaiaretic acid, trihydroxybutyrophenone, uric acid and derivatives thereof, mannose and derivatives thereof, superoxide dismutase, N-[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]sulfanilic acid (and salts thereof, for example the disodium salts), zinc and derivatives thereof (e.g. ZnO, ZnSO₄), selenium and derivatives thereof (e.g. selenium methionine), stilbene and derivatives thereof (e.g. stilbene oxide, trans-stilbene oxide) and the derivatives suitable according to the invention (salts, esters, ethers, sugars, nucleotides, nucleosides, peptides and lipids) of those mentioned active ingredients. HALS (=“Hindered Amine Light Stabilizers”) compounds may also be included. Further synthetic and natural antioxidants are listed e.g. in patent IA/00025731: structures 1-3 (page 2), structure 4 (page 6), structures 5-6 (page 7) and compounds 7-33 (page 8-14).

The amount of antioxidants present is usually from 0.001 to 30% by weight, preferably from 0.01 to 3% by weight.

Hydrotropic Agents

To improve the flow behavior it is also possible to employ hydrotropic agents, for example ethoxylated or non-ethoxylated mono-alcohols, diols, or polyols with a low number of carbon atoms or their ethers (e.g. ethanol, isopropanol, 1,2-dipropanediol, propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, diethylene glycol monomethyl ether; diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, and similar products).

F. DePolo—A short textbook of cosmetology, Chapter 7, Table 7-2, 7-3, 7-4 and 7-5, p210-219.

Bacteria-Inhibiting Agents

Typical examples of bacteria-inhibiting agents are preservatives that have a specific action against gram-positive bacteria, such as 2,4,4′-trichloro-2′-hydroxydiphenyl ether, chlorhexidine (1,6-di(4-chlorophenyl-biguanido)hexane), or TCC (3,4,4′-trichlorocarbanilide). A large number of aromatic substances and ethereal oils also have antimicrobial properties. Typical examples are the active ingredients eugenol, menthol, and thymol in clove oil, mint oil, and thyme oil. A natural deodorising agent of interest is the terpene alcohol farnesol (3,7,11-trimethyl-2,6,10-dodecatrien-1-ol), which is present in lime blossom oil. Glycerol monolaurate has also proved to be a bacteriostatic agent. The amount of the additional bacteria-inhibiting agents present is usually from 0.1 to 2% by weight, based on the solids content of the preparations.

Perfume Oils

The compositions may contain perfume oils, such as mixtures of natural and/or synthetic aromatic substances. Natural aromatic substances are, for example, extracts from blossom (lilies, lavender, roses, jasmine, neroli, ylang-ylang), from stems and leaves (geranium, patchouli, petitgrain), from fruit (aniseed, coriander, carraway, juniper), from fruit peel (bergamot, lemons, oranges), from roots (mace, angelica, celery, cardamom, costus, iris, calmus), from wood (pinewood, sandalwood, guaiacum wood, cedarwood, rosewood), from herbs and grasses (tarragon, lemon grass, sage, thyme), from needles and twigs (spruce, pine, Scots pine, mountain pine), from resins and balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax). Animal raw materials also come into consideration, for example civet and castoreum. Typical synthetic aromatic substances are, for example, products of the ester, ether, aldehyde, ketone, alcohol, or hydrocarbon type. Aromatic substance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allylcyclohexyl propionate, styrallyl propionate, and benzyl salicylate. The ethers include, for example, benzyl ethyl ether; the aldehydes include, for example, the linear alkanals having from 8 to 18 hydrocarbon atoms, citral, citronellal, citronellyl oxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, filial, and bourgeonal; the ketones include, for example, the ionones, isomethylionone, and methyl cedryl ketone; the alcohols include, for example, anethol, citronellol, eugenol, isoeugenol, geraniol, linalool, phenyl ethyl alcohol, and terpinol; and the hydrocarbons include mainly the terpenes and balsams. It is preferable, however, to use mixtures of various aromatic substances that together produce an attractive scent. Ethereal oils of relatively low volatility, which are chiefly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, clove oil, melissa oil, oil of cinnamon leaves, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil, and lavandin oil. Preference is given to the use of bergamot oil, dihydromyrcenol, filial, lyral, citronellol, phenyl ethyl alcohol, hexyl cinnamaldehyde, geraniol, benzyl acetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, tangerine oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, muscatel sage oil, damascone, bourbon geranium oil, cyclohexyl salicylate, vertofix coeur, iso-E-Super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romillat, irotyl, and floramat alone or in admixture with one another.

Colorants

The composition may contain colorants that are suitable and permitted for cosmetic purposes, as compiled, for example, in the publication “Kosmetische Farbemittel” of the Farbstoffkommission der Deutschen Forschungsgemeinschaft, Verlag Chemie, Weinheim, 1984, pages 81 to 106. The colorants are usually used in concentrations of from 0.001 to 0.1% by weight, based on the total mixture.

Polymeric Beads or Hollow Spheres as SPF Enhancers

The composition may include SPF enhancers, such as non-active ingredients like styrene/acrylate copolymers, silica beads, spheroidal magnesium silicate, and crosslinked polymethylmethacrylates (PMMA; Micopearl M305 Seppic). Hollow-sphere additives (Sunspheres® ISP, Silica Shells Kobo.) deflect radiation and the effective path length of the photon is therefore increased (EP 0 893 119). Some beads provide a soft feel during spreading. Moreover, the optical activity of such beads, e.g. Micropearl M305, can modulate skin-shine by eliminating reflection phenomena and may indirectly scatter the UV light.

Other Additives

The compositions may also contain antifoams, such as silicones, structurants, such as maleic acid, solubilizers, such as ethylene glycol, propylene glycol, glycerol, or diethylene glycol, opacifiers, such as latex, styrene/PVP, or styrene/acrylamide copolymers, complexing agents, such as EDTA, NTA, alaninediacetic acid, or phosphonic acids, propellants, such as propane/butane mixtures, N₂O, dimethyl ether, CO₂, N₂, or air, so-called coupler and developer components as oxidation dye precursors, reducing agents, such as thioglycolic acid and derivatives thereof, thiolactic acid, cysteamine, thiomalic acid, or mercaptoethanesulfonic acid, or oxidizing agents, such as hydrogen peroxide, potassium bromate or sodium bromate.

Suitable insect repellents for use in the compositions described herein include N,N-diethyl-m-toluamide, 1,2-pentanediol, or insect repellent 3535. Suitable self-tanning agents for use in the compositions described herein include dihydroxyacetone and/or erythrulose or dihydroxy acetone and/or dihydroxy acetone precursors as described in WO 01/85124 and/or erythrulose.

Example 1. Preparation of HUCPVC Total Protein Product (HTPP)

Protocol Overview:

Cord Dissection

The umbilical cord was disinfected with Chloraprep and then rinsed with DPBS in order to remove blood and other debris. Cord dissection was performed on a dissection table: 1) cut a shallow circumferential incision, 2) carefully and gradually peel the thin amniotic epithelial membrane. After another rinse in DPBS, the denuded cord was then separated into the three umbilical vessels (2 arteries and 1 vein) and cut into 10 cm segments.

Cryopreservation of Cord Vessels

The vessels were incubated with cryopreservation media (CryoStorCS10) on gentle rotation at 4° C. for 45 minutes. After incubation, vessels were transferred individually into cryovials containing cryopreservation media, and cryopreserved using a controlled rate freezer at 1 degree per minute freezing speed. For long term storage, the samples were stored in liquid nitrogen.

HUCPVC Isolation

A CELLstart-coated flask (1:50 dilution in PBS+/+) was preloaded with complete culture medium and placed in the incubator. The vessels were then thawed and incubated at room temperature in DPBS for 5 minutes. Another 2 rounds of incubation, 5 minutes and 10 minutes, were performed after doubling the volume. After a final rinse in DPBS, the perivascular Wharton's jelly was tentatively stripped from each vessel. The jelly was then cut into fragments approximately 2 mm by 2 mm and seeded into preloaded CELL-coated flask as P0 culture.

P0 was cultured for 7-14 days based on cell outgrowth. Upon desired confluency being reached, P0 culture was rinsed with DPBS and incubated in a recombinant cell dissociation enzyme (trypLE) at 37° C. for 10 minutes. Complete culture medium was subsequently added to the flask. The cell suspension was then filtered through a cell strainer to remove tissue debris and centrifuged at 290×g for 10 minutes at 4° C. A viable cell count was obtained by hemocytometer or ViCell technology after cells were re-suspended in complete culture medium.

HUCPVC Expansion

P1-P3 cells were then seeded at 2000 cells/cm²in human fibronectin-coated flasks (0.75 μg/cm²) preloaded with complete culture medium, 4 days per passage. At harvest, cells were dissociated with trypLE incubation at 37° C. Complete culture medium was subsequently added to the flask. The cell suspension was then centrifuged at 290×g for 10 minutes at 4° C. A viable cell count was obtained by a hemocytometer or ViCell technology after cells were re-suspended in complete culture medium. P3 cells were cryopreserved in 1:1 basal medium:EZCPZ by either a controlled rate freezer or an isopropanol-based freezing container (Mr. Frosty).

HTPP Preparation

The cells were thawed by a 2-step dilution using pre-warmed complete medium. The cell suspension was then centrifuged at 290×g for 10 minutes at 4° C. and resuspended in 0.9% saline solution. A viable cell count was obtained by a hemocytometer or ViCell technology. The cells were incubated at 37° C. in 0.9% saline solution for 6 hours with intermittent gentle mixing. The cells were homogenized 4 times for 30 seconds each time with 1-minute intervals using a bead mill homogenizer. 0.9% saline solution was then used to top up the homogenized cell mixture to 1 million cells per ml (based on the viable cell count after thawing). The final samples were filtered through 0.22 um filter and then aliquoted and stored in a −80° C. freezer.

Detailed Protocol:

1. Dilute CELLstart (CELLStart CTS—Life Technologies (A10142-01)) 1:50 with PBS (+Ca/+Mg) (Life Technologies (14040-182)), mix and add 78 μL/cm²to the tissue culture container per manufacturer instructions

2. Place in CO₂incubator at 37° C. for 2 hours

3. Use either immediately or store for later:

- a. Immediate use—aspirate coating solution and use without rinsing or
- b. Later use—do not aspirate, parafilm vented caps and store at 4° C. up to 2 weeks; at time of use, aspirate coating solution and use without rinsing
  
  Note: In each case, after aspiration, pre-load flask with complete medium (RBI Complete medium (KT-016)) and allow to warm up in CO₂incubator at 37° C. for at least 15 minutes prior to seeding explanted tissue or cells
  
  4. Open Disinfection Kit (Forceps, Mat, Chloraprep applicator) with mat laid out.
  
  5. Pipette 100 mL of PBS to media bottle.
  
  6. Using forceps, transfer umbilical cord to the mat.
  
  7. Place ruler over the cord to measure length and across the cord to measure the girth and record the information on the umbilical cord processing log sheet.
  
  8. Wipe down cord surface, including the ends, for 30 seconds with Chloraprep applicator. Allow cord to dry completely; approximately 30 seconds.
  
  9. Place cord in PBS rinse bottle, cap and shake vigorously to remove blood and debris. Transfer rinsed cord to a specimen container.
  
  8. Remove dirty mat and forceps from the BSC.
  
  9. Open Dissection Kit (Dissection table, Mat, Forceps (2), Scalpel handle & blade No. 15) and place table on the mat.
  
  10. Transfer cord to dissection table. Insert 0.5-1 cm of cord under the pressure plate and tighten all the way with screws.
  
  11. Make a shallow circumferential incision of the epithelium a few millimeters away from the pressure plate with the scalpel.
  
  12. Using forceps and blunt dissection, carefully peel the thin amniotic epithelial membrane bit by bit across the circumference at the incision site until a continuous flap of epithelium (approx. 3-4 mm) has been lifted.
  
  13. Holding forceps perpendicular to the cord, firmly grasp a large flap of epithelium (i.e. not grabbing by the tip) and pull it a few mm down the cord. Rotate to work all around the cord, pulling the “sock” incrementally towards the free end. Continue until the entire membrane is stripped away. Discard amniotic epithelium in a biohazard waste bin.
- a. If the membrane does not separate as one whole piece and/or break apart during this step, trace back and try to re-establish the “sock”. Care must be taken as this thin layer can tear easily.
- b. Be sure to remove only a thin layer. If the layer becomes too thick, use the scalpel to scrape back excess WJ.
  
  14. Once the entire tube of epithelium is removed, sever the cord just below the incision site.
  
  15. Transfer the denuded cord to the specimen container and add 50 mL of DPBS.
  
  16. Remove the dissection table from the BSC.
  
  17. Transfer cord to the mat. Using forceps, separate the 3 umbilical vessels and cut into 10 cm segments, cutting out blood clots where possible.
  
  18. Proceed to cryopreservation procedure, if desired. Otherwise, proceed to step 32.
  
  19. Place 3 vessels (2 arteries+1 vein) in a 50 mL tube and add 10 mL of CryoStor CS10 (CryoStor CS10 cryopreservation solution—BioLife Solutions (210102)). Seal cap with Parafilm.
  
  20. Place on a tube rotator at 4° C. for 45 minutes on gentle rotation.
  
  21. Transfer vessels to mat inside BSC. DO NOT discard CS10 solution.
  
  22. Add 1 mL of spent CS10 to a 5 mL cryovial (to prevent trapped air), then place one vessel segment inside; tap to release trapped air bubble. Top up to 4 mL with spent CS10, if space allows.
  
  23. Use a controlled rate freezer (CRF) with a program set at 1 deg/min freezer to cryopreserve. Once cycle is complete (>60 min), transfer samples to LN for long term storage.
  
  24. When ready to thaw cryopreserved vessels, pre-load the CellStart-coated T225 flask with
  
  24 mL of complete culture medium and place in a CO₂incubator to warm.
  
  25. Remove vials (3) from LN and place in a 37° C. water bath.
  
  26. Thaw completely (˜2-2.5 minutes) and remove immediately while still cold.
  
  27. Transfer vessels to a specimen container with forceps.
  
  28. Add 15 mL of PBS (—Ca/—Mg) (PBS (—Ca/—Mg)—Life Technologies (14190-250)). Swirl and incubate for 5 min at RT.
  
  29. Add another 15 mL PBS and incubate for 5 min at RT.
  
  30. Add 30 mL PBS and incubate for a further 10 min at RT.
  
  31. Transfer vessels to a 50 mL tube and add 20 mL PBS for a final rinse. Then transfer vessel to a clean mat.
  
  32. Using blunt dissection, strip off the perivascular Wharton's jelly (PWJ) from each vessel, careful not to tear into the smooth muscle wall.
  
  33. Place PWJ in a clean 50 mL tube with the cap on to keep it from drying.
  
  34. Once all tissue has been stripped, pour entire PWJ content onto the cutting board and cut into small fragments using a knife. This is achieved by rocking the knife back and forth in a single plane over the tissue while applying force downward. Rotate knife perpendicular to the original plane and repeat cutting. Continue cutting in this manner until tissue fragments are approximately 2 mm×2 mm (˜5-10 minutes).
  
  35. Transfer minced PWJ back to 50 mL tube using a scoopula.
  
  36. Transfer the coated flask, now warmed, from the incubator to a biosafety cabinet (BSC).
  
  37. Pre-wet the tip of a wide-tip pipet (Wide-tip 10 mL pipet—VWR (89130-912)) with culture medium from the flask before using it to transfer tissue. Seed flask with all of the minced tissue.
  
  38. Gently tap sides and rock flask back and forth to break up tissue clumps and distribute evenly across culture surface.
  
  39. Return flask to incubator and culture per Explant (P0) Culture SOP below.

  42. Discard spent medium and loose tissue bits using a 10 mL wide tip pipet into a waste bottle.
  
  43. Rinse with 24 mL PBS×2.
  
  Note: Do not add PBS to culture surface. Instead, add to the opposite side so that tissue bits don't get flushed off surface.
  
  44. Discard PBS to waste bottle.
  
  45. Using a regular 10 mL serological pipet, add 12 mL TrypLE (TrypLE Express—ThermoFisher (12604-021)) and incubate at 37° C. for 10 minutes.
  
  46. Observe. Further incubate in 5-minute intervals if needed.
  
  47. Tap gently to help dissociate tissue/cells.
  
  48. Observe under microscope to confirm all cells have dissociated. If more time is required, incubate for another 5 minutes and observe, etc.
  
  49. Add 24 mL of complete medium to flask.
  
  50. Place a cell strainer over a new 50 mL tube. Mix and transfer cell/tissue suspension to tube, straining out the tissue bits in the process.

Example 3. Perivascular Tissue Lysate Reduces Inflammation

Carrageenan 1% w/v was injected into the ventral (underside) of a mouse paw at time zero and either saline (control), perivascular tissue lysate (PTL), or HTPP was injected simultaneously lateral to the Achilles tendon. Paw circumference measurements were made using a cotton thread at 4, 24, and 48 hours post-injection and normalized to the value at time zero. Carrageenan is known to have a biphasic inflammatory effect with an initial swelling at 4 hours followed by a second swelling at 72 hours. By four hours, the paws had swollen in both groups (n=6 ten-week old CD1 mice/group). As shown in FIG. 1, paw swelling had diminished in both groups by 24 hours, although it decreased more in the paws injected with PTL compared to the paws injected with saline. However, the saline group was swelling again by 48 hours while the PTL group continued to recover and paw diameter was almost back to normal. These data show that while no difference between groups was evident at 4 hours, a significant effect of PTL was seen at 48 hours (p=0.003, two-way ANOVA). Myeloperoxidase (MPO) levels were also measured by ELISA to assess the effects of saline and PTL on immune cell extravasation into the injected paw. As shown in in FIG. 2, a marked decrease in MPO level was observed in in the injected paw of mice treated with PTL compared to mice treated with saline and carrageenan. A decrease in MPO is indicative of a reduction in neutrophil infiltration. In addition, pro-inflammatory cytokine tumor necrosis factor-alpha (TNFα) concentration was also measured in the injected paws using ELISA. As shown in in FIG. 3, TNFα concentration was reduced in the injected paw of mice treated with

PTL compared to mice treated with saline (control) at four 4 hours after injection. The TNFα concentration was further reduced in the injected paw of mice treated with PTL 24 hours after injection. The concentration of TNFα in the injected paw of mice treated with HTPP was lower at 24 hours after injection than that observed in the injected paw of mice treated with PTL. These data indicate that PTL and HTPP reduce inflammation, and that HTPP may have a stronger anti-inflammatory effect than PTL.

Example 4. Perivascular Tissue Lysate Promotes Cell Proliferation in Culture

Perivascular tissue lysate was mixed from two donors (D2 and D3) and produced by micronizing perivascular tissue (1 gram) in 3 mL of saline=100% concentration. This was then used to produce dilutions of 1%, 0.1% and 0.01% in basal medium (Rooster Bio Basal Medium). HUCPVCs were then cultured in basal medium containing the diluted perivascular tissue lysate or in basal medium alone (control).

FIG. 4 contains a graph representing the number of HUCPVCs in culture on day 4 normalized to the control. As shown in FIG. 4, there were a greater number of HUCPVCs in cultures grown with basal medium containing perivascular tissue lysate compared to control.

Example 5. HUCPVC Total Protein Product Promotes Cell Proliferation in Culture

HUCPVC Total Protein Product (HTPP) was produced from freshly-harvested HUCPVCs (1 million cells/mL saline) and lysed by repeated freeze-thaw cycles. This was then used to produce dilutions of 1%, 0.1% and 0.01% in basal medium (Rooster Bio Basal Medium). HUCPVCs were then cultured in basal medium containing the diluted HTPP or in basal medium alone (control).

FIG. 5 contains a graph representing the number of HUCPVCs in culture on day 4 normalized to the control. As shown in FIG. 5, there were a greater number of HUCPVCs in cultures grown with basal medium containing HTPP compared to control at all dilution concentrations. FIG. 6 contains a graph representing the number of HUCPVCs in culture on day 7 normalized to the control, which demonstrates that this effect was magnified as HUCPVCs continued to divide during additional days in culture.

Example 6. Mass Spectrometry Analysis of Samples of Perivascular Tissue and Whole Umbilical Cord Tissue

Mass spectrometry analysis was performed to identify proteins present in samples of whole cord and perivascular tissue. The proteins identified were then categorized based on functions of interest. As shown in FIGS. 5A and 5B, the total number of proteins of interest in perivascular tissue (FIG. 7B) was almost double that in whole cord tissue (FIG. 7A). Also, the percentages of the groups of proteins, while similar in both groups, show some distinct differences—particularly the immune response group.

Example 7. The HUCPVC Total Protein Product Reduces the Number of Cells in a Joint Following Local Inflammation

Carrageenan 1% w/v was injected into the temporomandibular (jaw) joint of a rat at time zero to create an inflammatory reaction. Saline or a 10% dilution of the HTPP (10% dilution from the production concentration based on a cell equivalent of one million cells/mL) was injected simultaneously (n=8/group). Injection volume was 0.2 microliters. Thus, the cell equivalent of 200,000 cells divided by 10=20,000 cell equivalents were injected. Synovial fluid was then aspirated from the joint at three time points: 4, 48, and 72 hours. As shown in FIG. 8, at the first time point sampled (4 hours), there was a marked decrease in the number of aspirated cells from the joint in rats administered HTPP, with the levels remaining constant after that time point. The p value for the difference at 4 hours is 0.01. These data show that the HTPP promotes a profound effect on (e.g., decreasing) the number of cells (e.g., immune cells) entering the synovial joint space as a result of the carrageenan administration. These data show that the HTPP is capable of reducing inflammation.

Example 8. The HUCPVC Total Protein Product Contains Proteins in Membrane Bound Compartments

A bicinchoninic acid assay (BCA) was used to measure total available protein in the HTPP. This returned a value of 24 μg/mL. However, this level was increased to 44.04 μg/mL following lysis, demonstrating that approximately 50% of the protein is contained in vesicles/exosomes. The vesicles/exosomes represent material secreted by the HUCPVCs during the HTPP production protocol, demonstrating that the HTPP contains not only the intracellular and transmembrane proteins, but also proteins secreted by the cells. These data demonstrate that the HTPP contains approximately 44 micrograms of protein per million cells and that the HTPP preparation protocol generates a product containing proteins from all possible cell sources that may be more representative of the proteins produced by the cells.

Example 9. Administration of HTPP to a Subject with Scleroderma

According to the methods disclosed herein, a physician of skill in the art can treat a patient, such as a human patient, with scleroderma to reduce joint pain, skin thickening or skin fibrosis, or skin tightness or immobility. To this end, a physician of skill in the art can administer to the human patient a HUCPVC Total Protein Product (HTPP) or a composition containing an HTPP. The HTPP may be administered to the patient, for example, by local injection to a joint or a region of skin thickening (e.g., intra-articular or subcutaneous injection) to treat joint pain or skin thickening or fibrosis associated with scleroderma, or may be applied topically to an area of thick or tightened or tightening skin. If the patient has a systemic form of scleroderma, the HTPP or HTPP-containing composition may be administered systemically, such as by intravenous injection. The HTPP or HTPP-containing composition can be administered in a therapeutically effective amount, such as from about 1,000 cell equivalents to about 1,000,000 cell equivalents (e.g., 1,000, 5,000, 10,000, 20,000, 50,000, 100,000, 250,000, 500,000, 750,000, or 1,000,000 cell equivalents). The HTPP or HTPP-containing composition can be administered bimonthly, once a month, once every two weeks, or at least once a week or more (e.g., 1, 2, 3, 4, 5, 6, or 7 times a week or more).

Following administration of the HTPP to a patient, a practitioner of skill in the art can monitor the patient's improvement in response to the therapy by a variety of methods. For example, a physician can monitor the patient's joint pain and skin thickness or tightness using standard approaches and patient self-reporting. A finding that the patient's joint pain improves, or that the patient's skin thickening or skin tightness is reduced or does not worsen, as compared to measurements taken prior to administration of the HTPP, indicates that the patient is responding favorably to the treatment. Subsequent doses can be determined and administered as needed.

Example 10. Administration of HTPP to a Subject with Psoriasis

According to the methods disclosed herein, a physician of skill in the art can treat a patient, such as a human patient, with psoriasis to reduce inflammation, flaking, or the size or number of flaky patches on the skin, or to prevent psoriasis from worsening. To this end, a physician of skill in the art can administer to the human patient an HTPP or a composition containing an HTPP. The HTPP may be administered to the patient, for example, by local injection to or near a region of the skin exhibiting red, white, or silvery patches of skin or may be applied topically to an affected area. For topical administration, the HTPP may be formulated in an ointment or lotion. The HTPP or HTPP-containing composition can be administered in a therapeutically effective amount, such as from about 1,000 cell equivalents to about 1,000,000 cell equivalents (e.g., 1,000, 5,000, 10,000, 20,000, 50,000, 100,000, 250,000, 500,000, 750,000, or 1,000,000 cell equivalents). The HTPP or HTPP-containing composition can be administered bimonthly, once a month, once every two weeks, or at least once a week or more (e.g., 1, 2, 3, 4, 5, 6, or 7 times a week or more).

Following administration of the perivascular lysate to a patient, a practitioner of skill in the art can monitor the patient's improvement in response to the therapy by a variety of methods. For example, a physician can monitor the appearance of the patient's skin using standard approaches. A finding that the patient's psoriasis lessens (e.g., the number or size of patches of flaky, red, white, or scaly skin is reduced) or does not worsen, as compared to measurements taken prior to administration of the HTPP, indicates that the patient is responding favorably to the treatment. Subsequent doses can be determined and administered as needed.

Example 10. Use of a Face Mask Containing an HTPP to Improve the Condition of the Skin

A subject who wishes to improve the condition, appearance, or texture of their skin can do so by applying an HTPP prepared as described herein above to their skin.

The HTPP can be applied, for example, as a topical composition, such as an ointment, lotion, cream, serum, etc. If desired, the topical composition can be applied, e.g., in connection with a mask. The mask may be a face mask (e.g., a sheet mask, cream mask, clay mask, gel mask, overnight mask (e.g., a sleeping mask), exfoliating mask, or enzyme mask) that contains the HTPP.

The subject may apply the composition to the skin (e.g., as part of a mask) 2-3 times per week, such as for at least about 15 to 30 minutes or for several hours, such as overnight.

If the mask is a sheet mask, the subject can use a fresh sheet mask for each application and discard the mask after use and may massage any remaining composition into the skin (e.g., the face, neck, and/or chest or other area of skin). If the mask is a cream, clay, gel, overnight, exfoliating, or enzyme mask, the subject may wash their skin to remove the mask after use. With continued use, the HTPP-containing mask may improve the subject's skin by reducing the appearance of redness, dryness, dark spots, or fine lines and/or improving skin brightness, firmness, texture, and hydration.

Example 11. Administration of a Cream Containing an HTPP to a Subject with Atopic Dermatitis

According to the methods disclosed herein, a physician of skill in the art can treat a patient, such as a human patient, with atopic dermatitis (eczema). To this end, a physician of skill in the art can prescribe the patient a medicated skin cream containing an HTPP that the patient may self-administer. The subject can topically apply the HTPP-containing skin cream to the affected area to treat the atopic dermatitis and reduce redness or itching. The medicated skin cream containing the HTPP can be applied once a week, twice a week, three times a week, four times a week, five times a week, six times a week, daily, or twice a day. The medicated skin cream containing the HTPP can be applied until the atopic dermatitis clears or the redness or itching is reduced or eliminated.

Following administration of the medicated skin cream containing the HTPP by the patient, a practitioner of skill in the art can monitor the patient's improvement in response to the therapy by a variety of methods. For example, a physician can monitor the appearance of atopic dermatitis (e.g., redness) and the patient's self-reported itchiness using standard approaches. A finding that the patient's atopic dermatitis lessens or clears (e.g., redness and/or itching is reduced or eliminated) compared to measurements taken prior to application of the medicated skin cream indicates that the patient is responding favorably to the treatment. Subsequent doses can be determined and administered as needed.
