| 摘要 |
One aspect of the present application relates to a method for modulating the growth state of an epithelial cell by ectopically contacting the epithelial cell, in vitro or in vivo, with a hedgehog therapeutic or ptc therapeutic in an amount effective to alter the rate (promote or inhibit) of proliferation of the epithelial cell, e.g., relative to the absence of administeration of the hedgehog therapeutic or ptc therapeutic. The subject method can be used, for example, to modulate the growth state of an epithelial tissue, such as for inducing the formation of skin or other cutaneous tissue, or for inducing growth of hair.
