Disclosed are means of enhancing therapeutic activities of fibroblasts through manipulation of nuclear receptor activation accomplished by, intra alia, alteration in hormone levels. In some embodiments angiogenic, and/or neurogenic, and/or immunomodulatory activities of fibroblasts are increased by normalization or augmentation of sex-specific hormones. In one embodiment a candidate for fibroblast therapy is administered hormones, pro-hormones, or growth factors to augment therapeutic activities of fibroblasts. In some embodiments fibroblasts are treated in vitro prior to administration with various hormones and/or growth factors in order to augment therapeutic activities of said cells.

The present disclosure relates to methods for culturing human epidermal keratinocytes. When keratinocytes are cultured on plates coated with a laminin containing an alpha-4 chain or an alpha-5 chain, in a xeno-free, chemically defined cell culture medium, they expand efficiently in vitro. Useful cell culture kits for culturing keratinocytes are also described herein, as are methods of using such cells for treatment of burns or chronic wounds.

The present invention is directed to purified preparations of dermal mesenchymal stem cells that are characterized by the cell surface expression of the ABCB5 P-glycoprotein. The cells may be used for any purpose that mesenchymal stem cells from other course are used. For instance they may be administered to treat an organ transplant recipient to improve allograft survival or as a treatment to patients with autoimmune diseases such as multiple sclerosis and rheumatoid arthritis.
