- the present invention relates to a composition for promoting stem cell activation comprising ischemia and a method for promoting activation of stem cells.
- the present invention also relates to stem cells whose activation is promoted by ischemia serum stimulation.
- stem cells As an alternative to solve these problems, interest in stem cells has increased, and pluripotent stem cells with the ability to form all organs through proliferation and differentiation have been treated for most diseases, as well as Parkinson's disease and various cancers. It is suggested that it can be applied to a variety of treatments, such as diabetes and spinal cord injury.
- Stem cells are cells that have the ability to self-replicate and differentiate into two or more new cells. Embryonic stem cells, induced pluripotent cells, and adult stem cells (adult stem cell) and the like are the most actively studied. In the case of embryonic stem cells or induced pluripotent stem cells, there are still limitations in applying them to the clinic due to stability issues such as ethical issues and tumor formation. In the case of adult stem cells, clinical studies have been conducted in patients due to its stability, but in the case of neural stem cells and cord blood cells, adult cells are transplanted to themselves. Autograft is not yet possible and there is a limit to transplant the nerve stem of others. Bone marrow or adipose-derived mesenchymal stem cells (mesenchymal stem cells) are the stem cells that are most actively studied in the clinic because they can be easily obtained in the human body.

- Ischemic induction from ischemia-induced ischemia was obtained after 1, 7, 14, and 28 days, and then trypsin-treated cells serially passaged from 2 passages to 6 passages were used to trypsin 1,300 rpm, After centrifugation for 3 minutes, pellets were resuspended with 1 ml of 90% ethanol and incubated overnight at 4 ° C. Ethanol was removed by centrifugation at 1500 rpm for 5 minutes and resuspended in 0.1% triton X-100, 20 ⁇ g / ml RNaseA PBS 500. After incubation at 37 ° C. for 30 minutes, 50 ⁇ g / ml of PI was added, and the change in cell cycle according to passage was measured according to ischemia serum treatment.
- the cells in the S and G2 / M phases of gene replication and cell division were increased in the group cultured with ischemia on day 1 compared with the control group cultured with FBS until 2-6 generation passage. It was. At 7, 14, and 28 days, the group cultured with ischemic serum was confirmed to increase compared to the control group cultured with FBS until 2-4 generation passage.
- the survival rate can be increased.
- Cell viability was compared and analyzed. Specifically, after subcultured with ischemic serum, 20% ischemic brain extracts were treated with cells to form an ischemic brain-like environment culture. After 24 hours, the cells were trypsinized, pelleted by centrifugation at 1300 rpm for 3 minutes with 5% FBS-PBS, and 150 ⁇ l of 1 ⁇ binding buffer was added thereto. Thereafter, 10 ⁇ l of AnnexinV FITC and 10 ⁇ l of 50 ⁇ g / ml PI were added and reacted at room temperature for 15 minutes, followed by 350 ⁇ l of 1 ⁇ binding buffer.
- stem cells cultured only with FBS show a greater number of beta-galactosidase staining-positive cells than stem cells cultured with ischemic serum obtained at 1, 7 and 14 days after ischemia.
- Visual confirmation was possible under a microscope (a).
- the percentages of the cells that were positive for beta-galactosidase staining in the total cells were measured and the ratios were plotted (b). This confirms that ischemic serum culture can slow the aging of stem cells.
- the levels of cytokines and growth factors contained in ischemia and normal serum used in Examples 1 and 2 were analyzed using a rat cytokine antibody array and ELISA of R & D System.

- TIMP-1 showed a tendency to decrease in ischemic serum on day 1, it was confirmed that statistically significant decrease in ischemic serum on day 7, day 14, 28 (c).
- VEGF tended to increase with time after ischemia (d).
- Ischemic serum was obtained from patients within 7 weeks after the onset of cerebral infarction, and the levels of cytokines and growth factors included were compared with those of normal subjects using human cytokine multiplex from BIO-RAD.
- the standard sample was vortexed with 250 ⁇ l of standard buffer, incubated for 5 minutes on ice, and then transferred to a standard vial for 5 minutes.
- 150 ⁇ l of standard buffer was added to each of tubes 2 to 8 of eight tubes, and 200 ⁇ l of standard solution was added to the first tube. Then 50 ⁇ l each was transferred from tube 1 to 2 and from 2 to 3 step dilution.
- 150 ⁇ l of reading buffer was added to the prepared filter plate, and the culture was sufficiently wetted by incubating for 5 minutes, and then the buffer solution was removed by vacuum filtration.
- the serum and normal serum of cerebral infarction patients were different in the levels of growth factors HGF, VEGF, BDNF, NGF and chemokines SDF-1, MCP-1, SCF.
- the levels of HGF and VEGF which can promote stem cell growth and autologous division, were high in serum of cerebral infarction patients (a), while BDNF and NGF, which induce differentiation of stem cells into neurons, were low.
- a serum of cerebral infarction patients
- BDNF and NGF which induce differentiation of stem cells into neurons
- chemokines SDF-1, MCP-1, and SCF which show positive chemotaxis in the body, were present in the serum of cerebral infarction patients at a lower level than the serum of normal subjects (c).
- the levels of substances regulating stem cell activity are different in serum of cerebral infarction patients compared to serum of normal persons.
- the amount of the above ingredient is prepared per ampoule (2 ml).
