Abstract

The present invention provides methods and compositions designed for treating a subject suffering from skin conditions, disorders or diseases. The compositions include fetal skin cell proteins obtained from fetal skin cells after induced cell lysis.

Claims (16)

1. A topical composition for treating a subject suffering from a skin condition, disorder or disease consisting essentially of an effective amount of lysate of cultured human fetal skin cells comprising human fetal skin proteins, wherein said cells were obtained from a cell bank prepared in vitro by cultivation and expansion of undifferentiated human fetal skin cells obtained from a human donor tissue of 12-16 weeks gestation, and a pharmaceutically or cosmetically acceptable topical carrier, wherein said lysate is incorporated in said composition at a concentration of between about 0.01% to about 5% by weight or volume of the final composition that is capable of promoting human dermal fibroblast proliferation, wherein said topical composition is capable of scarless wound healing upon topical administration, and wherein said topical composition is formulated in the form of an oil-in-water or water-in-oil emulsion or emulsion based cream, gel or hydrogel.

2. The composition of claim 1 , wherein said undifferentiated fetal skin cells are obtained from whole fetal skin tissue.

3. The composition of claim 1 , wherein said undifferentiated fetal skin cells are obtained from fetal skin tissue fragments.

4. The composition of claim 1 , further comprising analgesics, anesthetics, anti-inflammatory agents, antihistamine agents, antioxidants, counter irritants, antimicrobial agents, antibacterial agents, antifungal agents, preservatives, protein stabilizing agents, protease inhibitors, skin protectant agents, sunscreens or combinations and mixtures thereof.

5. The composition of claim 1 , wherein said composition is suitable for mucosal, ocular, rectal or vaginal administration.

6. The composition of claim 1 , wherein said lysate is incorporated in said composition at a concentration of 0.05% by weight or volume of the final composition.

7. The composition of claim 1 , wherein said lysate is incorporated in said composition at a concentration of 0.065% by weight or volume of the final composition.

8. The composition of claim 1 , wherein said lysate incorporated in said composition at a concentration of between 0.05% to 0.25% by weight or volume of the final composition.

9. The composition of claim 1 , wherein said cell lysate is obtained by induced cell lysis.

10. The composition of claim 9 , wherein said cell lysis is performed by one or more cycles of freeze-thawing.

11. The composition of claim 9 , wherein said cell lysis is performed with between 100 to 60/000,000 of cultured human fetal skin cells suspended in one milliliter of an aqueous system.

12. The composition of claim 11 , wherein said cell lysis is performed with between 10,000,000 to 20,000,000 of cultured human fetal skin cells suspended in one milliliter of an aqueous system.

13. The composition of claim 11 , wherein said aqueous system is a physiological buffer system.

14. The composition of claim 11 , wherein said aqueous system is a phosphate buffered saline system.

15. The composition of claim 1 , wherein said fetal skin proteins comprise one or more cytokines selected from the group consisting of epidermal growth factor (EGF), basic fibroblast growth factor (bFGF or FGF-2), beta nerve growth factor (b-NGF), fibroblast growth factors 4, 6 and 9 (FGF-4, FGF-6, FGF-9), granulocyte-colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor (GM-CSF), hepatocyte growth factor (HGF), insulin-like growth factor (IGF-I), interferon-gamma (IFN-γ), interleukins IL-1 alpha and IL-1 beta, interleukins IL-4, IL-6, IL-10 and IL-13, interleukin 1 receptor antagonist (IL-1ra), keratinocyte growth factor 1 (KGF-1 or FGF-7), placenta growth factor (PGF), platelet derived growth factor (PDGF), transforming growth factor beta 1 and 3 (TGF-β1, TGF-β3), tissue inhibitors of metallo-proteinase 1 and 2 (TIMP-1, TIMP-2), and vascular endothelial growth factor (VEGF).

16. The composition of claim 1 , wherein said dermal fibroblast proliferation is enhanced about 3-fold.
