This application claims the priority benefit of Korean Patent Application No. 10-2018-0074243 filed on Jun. 27, 2018, the disclosure of which is incorporated herein by reference.
Embodiments of the invention relate to a method of manufacturing a medium composition for cell culture. More particularly, embodiments of the invention relate to a method of manufacturing a medium composition for cell culture being able to increase a yield of a stem cell by mass culture and a method of manufacturing a crushed stem cell extract using a method of manufacturing a medium composition for cell culture and a 3-low extracting method of active ingredients of a stem cell being able to increase a yield of active ingredients of a stem cell, and an anti-inflammatory composition and a cell-generation therapy composition using the same.
Stem cells are undifferentiated cells that can differentiate into various types of body tissues. By ability to differentiate into various tissue cells, many researches to stem cells have been conducted. Adult stem cells among stem cells are easily obtained from sites, such as fat, bone marrow, cord blood, placenta, or so on. Since there are few ethical issues in adult stem cells, compared to embryonic stem cells, and an immune rejection is less when user's own cells are used, there have been many studies regarding adult stem cells.
A treatment for directly injecting adult stem cells is limited to a self-treatment due to an immune rejection and the like. To overcome the limitation of the self-treatment, a removal of a membrane where immunogenicity that causes an immune rejection is attached through crushing stem cells is one of methods. The inventors of this application established a concept of the above-mentioned crushed stem cell extract and applied for a patent application for an original patent regarding the same. The advantage of the original patent is that there is universality that anyone can use the crushed stem cell extract by removing a membrane where immunogenicity that causes an immune rejection is attached. There is a reason for mass culture, and it contributes popularization and industrialization of stem cells as a result.
Thus, in order to achieve popularization and industrialization of stem cells, continuous research and development for methods useful for mass culture of stem cells and methods for extracting active ingredients of stem cells is required.

First Step: A stem cell or stem cells are extracted from any one of human fat, bone marrow, cord blood, or placenta. In the invention, fat is collected by liposuction, and a fat stem cell of the fat is separated and purified by enzyme treatment and centrifugation several times.
Second Step: The separated stem cell or stem cells are cultured using a culture medium manufactured by using the medium composition for mass culture of the invention described above. When the medium composition for mass culture of the stem cell is used, a growth rate of the stem cell can be increased and a yield of the stem cell can be increased.

1-2. Result
The cartilage cell was confirmed by using CD44, which is a specific marker of an cartilage cell.
2-1. Inhibition Effect of Cytotoxic and Nitric Oxide (NO) Generation
1) A cartilage cell was treated with the crushed stem cell extract by concentration and cultured for 24 hours, and cell viability was measured to confirm toxicity to the cell.
2) The cartilage cell was treated with IL-1α to cause inflammation.
3) Inhibition of Nitric Oxide (NO), which is an inflammation mediator, was confirmed by treating the inflammatory cartilage cell with the crushed stem cell extract by concentration.
2-2. Result
1) As a result of measuring the cell viability through the treatment by concentration, there was not cytotoxicity at concentrations up to 20 ng/ml (that is, concentrations of 0, 5, 10, 20 ng/ml).
2) In the cells treated with IL-1α, which is an inflammation inducer, increase in NO was found. As a result of treating the inflammatory cartilage cell with the crushed stem cell extract by concentration, the inflammatory was inhibited by about 30% at a concentration 20 ng/ml (a concentration to the cell that the inflammation is not induced is 20 ng/ml, and concentrations to inflammatory cells are 5, 10, 20 ng/ml)
3-1. Change in iNOS, COX-2 and NF-kB Expression
1) A relationship between NO generation and expression of COX-2 and NF-kB was confirmed by applying Carprofen (non-steroidal substance), which is a positive control group, and the crushed stem cell extract to an IL-1α-treated cartilage cell.
NO: a value increasing when inflammation occurs
COX-2: a king of protein, a material that activity thereof increases by an inflammatory factor and then decreases as inflammation disappears
2) Effect of a treatment to the inflammatory cartilage cell with the crushed stem cell extract on the expression of NF-κB was confirmed.
3-2. Result
1) As a result that the cartilage cell treated with IL-1α to induce inflammation was treated with the crushed stem cell extract,

2) It can be seen that a migration of an NF-κB protein by IL-1α into a nucleus is inhibited in the cartilage cell treated with the crushed stem cell extract, and thus, a NF-κB pathway, which is a main inflammatory signal pathway induced by IL-1α, can be blocked.
4. Effect on iMAPKs Activity
1) An iMAPKs activity was confirmed by treating the cartilage cell where inflammation was generated by IL-1α with the crushed stem cell extract.
1) Identification of anti-inflammatory mechanism

As shown in
The efficacy of the active ingredients of the crushed stem cell extract according to the invention is as follows.
First, dementia is caused by a degeneration of beta amyloid toxin protein and tau protein. When cord-blood-derived mesenchymal stem cells are repeatedly transplanted into both hippocampus of Alzheimer's disease mouse, a memory capacity is increased, an amount of beta amyloid in the brain is decreased, an amount of β-secretase1, which is an enzyme that produces beta amyloid, is reduced in the brain tissue of mouse, secretion of inflammatory cytokines from microglial cells is suppressed, and secretion of anti-inflammatory cytokines is increased. By the above results, hyperphosphorylation of tau protein can be inhibited.
Therefore, it has been found that the mesenchymal stem cells inhibit a progression of Alzheimer's disease and reduce the amount of beta amyloid toxic protein which is the cause of dementia. The crushed stem cell extract (the shelled stem cell) is a material where active ingredients of a stem cell are concentrated to remove immune rejection, and thus, may be used to treat dementia. Further, since a yield of the cell and yield of the active ingredients are increased according to the invention, it can be used as a therapeutic agent having less risk and excellent effect than using the conventional stem cell itself.
In addition, a gum disease is caused by inflammation of a root of teeth, a bone of the gum, gum, or so on. The crushed stem cell extract according to the invention can help to regenerate the gum and the bone of the gum.
That is, growth factors of the stem cell can be used as a gum treatment or therapy because they help to inhibit inflammation, regenerate a bone, a cartilage, a gum cell, and promote wound healing regeneration. Especially, pro-collagen, a collagen network like a mesh, adheres a cell to another cell firmly, and provides an environment in which cells are made and many parts of a body such as blood vessels, bones, and joints function properly, and thus the crushed stem cell extract can be used as a treatment for the gum disease. Further, since the yield of the cell and the yield of the active ingredients are increased according to the invention, it can be used as a therapeutic agent having less risk and excellent effect than using the conventional stem cell itself.
An arthritis or a periarthritis is caused by inflammation around joints by a problem such as aging and injury. The crushed stem cell extract of the invention can be used as a treatment agent for an arthritis or a periarthritis because it help to inhibit inflammation, regenerate a bone, a cartilage, a cell, and promote wound healing regeneration. Especially, pro-collagen, a collagen network like a mesh, adheres a cell to another cell firmly, and provides an environment in which cells are made and many parts of a body such as blood vessels, bones, and joints function properly, and thus the crushed stem cell extract can be used as a treatment for the arthritis or the periarthritis. Further, since the yield of the cell and the yield of the active ingredient are increased according to the invention, it can be used as a therapeutic agent having less risk and excellent effect than using the conventional stem cell itself.
A cause of hair loss is various, such as environmental factors, genetic factors, or so on. VEGF growth factor of the crushed stem cell extract according to the invention helps hair follicle growth and hair strengthening by stimulating KGF and hair roots, and thus it can be used as a therapeutic agent for the hair loss. Further, since the yield of the cell and the yield of the active ingredients are increased according to the invention, it can be used as a therapeutic agent having less risk and excellent effect than using the conventional stem cell itself.
