Abstract

The present invention relates to a composition for skin regeneration, using a culture medium or a secretion in the culture of an embryonic stem cell-derived endothelial progenitor cell, and to the use thereof. As the present invention uses the secretion in the culture as a medicine and not the embryonic stem cell-derived endothelial progenitor cell itself, the risk of teratoma formation is prevented, and angiogenic activity is promoted to achieve improved effectiveness in healing wounds and burn wounds. The composition of the present invention, when used as a material in cosmetics, increases collagen synthesis and thus prevents skin aging. Particularly, the composition of the present invention in which the secretion in the culture is concentrated into a high concentration provides superior wound-healing effects as compared to a conventional human growth hormone (hGH).

Claims

1. A composition for skin regeneration, comprising secretions from a culture of embryonic stem-cell derived endothelial progenitor cells or fractions thereof.

2. The composition for skin regeneration according to claim 1, wherein the embryonic stem cells are human embryonic stem cells.

3. The composition for skin regeneration according to claim 1, characterized in that the culture secretions or fractions thereof are concentrated 50 times or more.

4. The composition for skin regeneration according to claim 1, wherein the composition is used in healing wounds, healing burn wounds, or skin cosmetics.

5. The composition according to claim 1, wherein the composition is used in a cosmetic product for improving wrinkles or preventing skin aging.

6. A composition for skin regeneration, comprising 1,250-1,250,000 pg/ml of epidermal growth factor (EGF), 35-35,000 pg/ml of (basic) fibroblast growth factor (FGF-2), 650-650,000 pg/ml of platelet-derived growth factor-AA (PDGF-AA), and 400-400,000 pg/ml of vascular endothelial growth factor (VEGF).

7. The composition for skin regeneration according to claim 6, further comprising one or more proteins selected from the group consisting of 4-4,000 pg/ml of Flt-3 ligand, 2-2,000pg/ml of interleukin-1α

(IL-1α

), 2-2,000 pg/ml of interleukin-1β

(IL-1β

), 0.2-200 pg/ml of interleukin-17 (IL-17), 2-2,000 pg/ml of platelet-derived growth factor-BB (PDGF-BB), and 2-2,000 pg/ml of Rantes (CCL5).

8. The composition for skin regeneration according to claim 6, further comprising one or more proteins selected from the group consisting of 160-160,000 pg/ml of fractalkine), 75-75,000 pg/ml of granulocyte macrophage colony-stimulating factor (GM-CSF), 400-400,000 pg/ml of interleukin-6 (IL-6), 19,000-19,000,000 pg/ml of interleukin-8 (IL-8), 34-34,000 pg/mi of interleukin-9 (IL-9), 45-45,000 pg/ml of chemokine IP-10, and 6-6,000 pg/ml of monocyte chemoattractant protein-1 (MCP-1)

9. The composition for skin regeneration according to claim 6, wherein the composition is used in healing wounds, healing burn wounds or in skin cosmetics.

10. The composition according to claim 6, wherein the composition is used in a cosmetic product for improving wrinkles or preventing skin aging.

11. A method for healing wounds, healing burn wounds, or skin cosmetics, comprising

(a) a step for culturing embryonic stem-cell derived endothelial progenitor cells;

(b) a step for removing the endothelial progenitor cells and preparing the secretions from the culture or fractions thereof; and

(c) a step for applying the culture secretions or fractions thereof to the skin of a mammal.

12. The method for healing wounds, healing burn wounds, or skin cosmetics according to claim 11, further comprising a step for concentrating the culture secretions or fractions thereof 50 times or more.

13. The method for healing wounds, healing burn wounds, or skin cosmetics according to claim 12, characterized in that the step for concentration uses a concentration system using a TFF membrane in order to concentrate only those components that are 10 KDa or more.
