PURPOSE:To obtain a medicine capable of selectively proliferating only an epitheliocyte. CONSTITUTION:This epitheliocyte growth promoter comprises a hepatic parenchyma cell growth factor (HGF) as an active ingredient. HGF may be derived from a human or animal tissue or blood component or may be produced by gene recombination. In this case, a host cell of the gene recombination may be Escherichia coli, Bacillus subtilis, yeast, a filamentous fungus, a plant or an animal cell. The epitheliocyte growth promoter specifically promotes growth of only a normal epitheliocyte and has promoting action on cell motion. Consequently, the epitheliocyte growth promoter is suitable for use as various medicines, a growth agent for hair root cells and a cosmetic including wound treatment and skin ulcer treatment. Since the epitheliocyte growth promoter has neither multiplication activity of fibroblast nor canceration promotion activity of cell, it is utilized as a medicine having low adverse effect. |
