Definitions
- the present invention relates to a method for increasing the stem cell capacity (stemness) of human mesenchymal stem cells.
- MSCs Mesenchymal stem cells
- the MSCs are various types of mesoderm lineages in vivo, such as osteoblasts, chondrocytes, tendon cells, adipocytes, myocytes, fibroblasts, and the like. Can be differentiated into In addition, under appropriate media conditions, they can cross-differentiate into neurons, cardiomyocytes, endothelial cells, and hepatocytes.
- bone marrow MSCs express class I MHC antigens, but not class II, or express stimulatory molecules that indicate that MSCs lack immunogenic activity (Klyushnenkova E et al., J Biomed Sci, 12 (1): 47-57). , 2005).
- MSCs exhibit immunosuppressive activity and can therefore be used as graft promoters, fetal grafts and inhibitors of host diseases (Le Blanc K et al., Lancet, 363 (9419): 1439-1441, 2004 El-Badri NS et al., Exp Hematol, 26 (2): 110-116, 1998).
- MSCs can be separated from various adult tissues such as bone marrow, adipose tissue, cord blood, peripheral blood, neonatal tissues, human placenta, etc., but the number of MSCs obtained from adult tissues is limited.
- the minimum number of cells required for cell therapy or regenerative medicine is around 1 ⁇ 10 9 , and the amount is even greater if conditions are included to establish conditions and establish standards.
- To supply this amount of existing mesenchymal stem cells of various origins requires at least 10 passages in vitro . The cells then become aging and deformed and no longer fit the concept of treatment. This is a big problem to be solved in the current culture system of mesenchymal stem cells. And even if the conditions and criteria are established with these cells, the cells may already run out of cells and require the use of other human mesenchymal stem cells when used for treatment. In order to use the mesenchymal stem cells as a cell therapy, it is necessary to develop a new method that can solve the above problems by increasing stem cell capacity.
- Stem cell capacity is a generic term for pluripotency capable of producing all cells, such as embryonic stem cells, and self-renewal capacity capable of producing infinitely similar cells. It is commonly used in the industry. Thus, it may be characterized by increased telomerase activity, increased expression of stemness acting signals, increased proliferation while maintaining undifferentiated cells, or increased cell migration activity. (Pittenger, MF et al. 1999. Multilineage potential of adult human mesenchymal stem cells. Science 284 (5411), 143-147).
- endothelin is a peptide produced in vascular endothelial cells and is composed of 21 amino acid residues and is known as a vasoconstrictive peptide. Endothelin has two S-S bonds in a molecule and is produced by modification of an ET precursor with an ET convertase. Endothelin-1 was first isolated from pig vascular endothelial cell culture in 1988, and most mammals have three types of isopeptides (ET-1, ET-2, and ET-3).
- Endothelin causes transient vasodilation and subsequent vasoconstriction.
- the three types of isopeptides have almost similar effects on transient vasodilation, whereas the effects of ET-3 on vasoconstriction are ET- It is only about a hundredth of one and ET-2.
- Two subtypes are known for the ET receptor, of which ETA is involved in vasoconstriction and ETB is involved in vasodilation.
- endothelin affects the stem cell capacity of human mesenchymal stem cells.
- Endothelin-1 (Endothelin-1) is an important factor that can increase the stem cell (stemness) of human mesenchymal stem cells (Mesenchymal stem cells)
- the conventional mesenchymal stem cell culture can be used to overcome the disadvantages of cell aging and to produce cells for cell therapy and regenerative medicine, and completed the present invention.
- the present invention provides a method for increasing the stem cell (stemness) of human mesenchymal stem cells (Mesenchymal stem cell), the method is endothelin- in stem cell culture medium- 1 (Endothelin-1) is to process the step of culturing.

- the present invention provides a method for increasing the stem cell capacity of human mesenchymal stem cells, the treatment of ET-1 to human mesenchymal stem cells in accordance with the present invention increases the stem cell capacity is possible long-term and mass culture, differentiation capacity There is an advantage that can secure a high yield of stem cells in the state.
- ET-1 has an effect of extending the length of telomeres, which are cellular aging markers, and is expected to be applicable as an anti-aging factor.
- Figure 1 shows the results confirmed by Western blot the amount of Oct4 protein expression according to ET-1 treatment in human mesenchymal stem cells.
- Figure 2 shows the results confirmed by real time PCR the amount of Oct4 mRNA expression according to ET-1 treatment in human mesenchymal stem cells.
- Figure 3 shows the real time gDNA PCR results using gDNA obtained from ET-1 treated human mesenchymal stem cells.
- Figure 4 shows the results of confirming the chromosome stability of ET-1 treated human mesenchymal stem cells by G-banding karyotype analysis.
- the present invention is characterized by providing a method for increasing the stem cell (stemness) of human mesenchymal stem cells (Mesenchymal stem cells, MSC), endothelin-1 (Endothelin-1, ET) in the stem cell culture for this purpose -1) treating and culturing.
- MSC mesenchymal stem cells
- Endothelin-1 Endothelin-1
- the present inventors studied to solve the problem that the stem cell capacity of the stem cells decreases as the number of passages during passage of the human mesenchymal stem cells in the prior art, stem cells by treating endothelin-1 in the human mesenchymal stem cell culture medium The ability was improved.
- Stem cell capacity related markers are known as Oct4, Nanog, Sox2, c-Myc, KLF4, etc.
- Oct4 which is known to express undifferentiated stem cells, plays a role in preventing cell differentiation and disappears when natural differentiation of cells begins. Therefore, it is possible to predict the degree of differentiation of stem cells according to the expression level of Oct4.
- telomeres are found at the ends of eukaryotic chromosomes and are a special structure that prevents degradation or end-to-end fusion of chromosomes.
- Telomere DNA is a primary structure consisting of short sequences of serial repeats (TTAGGG in humans), varying in length from hundreds of bp in lower eukaryotic cells to thousands of bp in mammalian cells. The telomeric DNA portion exhibits GC-rich, as in the centromere region.
- telomere shortening occurs after repeated cell division, which limits cell proliferation by activating cell cycle limitations that induce replicative senescence or apoptosis.
- telomeres that is, the length of the chromosomal end portion can be extended (see FIG. 3), and it was confirmed that no chromosomal aberration was caused by the endothelin-1 treatment (see FIG. 4).
- endothelin-1 treatment of human mesenchymal stem cells extends the telomere length, thereby prolonging the lifespan of stem cells, inhibiting aging, and increasing the growth and viability of the cells, thereby culturing the cells in large quantities. It can be seen that it is possible to overcome the limitations of conventional human mesenchymal stem cells in vitro culture.
- the present invention can provide a method for increasing the stem cell capacity of human mesenchymal stem cells by treating the endothelin-1, it can provide a human mesenchymal stem cells with increased stem cell capacity by the above method.
- Increased stem cell capacity of mesenchymal stem cells means that they are likely to differentiate into various mesoderm lineage cells such as bone, ligaments, and muscles.
- the present invention can provide a composition for increasing stem cell capacity of human mesenchymal stem cells comprising an endothelin-1 as an active ingredient.
- the "cell culture medium” is a human mesenchymal stem cell culture medium, wherein the human mesenchymal stem cells are derived from various tissues and pluripotent stem cells of the human body such as bone marrow, adipose tissue, umbilical cord blood, peripheral blood, neonatal tissue, and human placenta. It may be, but is preferably derived from bone marrow, but is not limited thereto.
- stem cell refers to an undifferentiated cell that is capable of differentiating into various cells constituting biological tissue, and is capable of non-limiting regeneration to form specialized cells of tissues and organs. .
- Stem cells are developable pluripotent or pluripotent cells. Stem cells can divide into two daughter stem cells, or one daughter stem cell and one derived (transit) cell, and then proliferate into mature, fully formed cells of the tissue.
