METHOD OF PREPARING HAIR PAPILLA CELL PREPARATION, COMPOSITION AND METHOD FOR REGENERATING HAIR FOLLICLE AND ANIMAL HAVING REGENERATED HAIR FOLLICLE

摘要

It is intended to provide a method of preparing a hair papilla cell preparation characterized by comprising eliminating an epidermal tissue form a skin tissue, treating the thus obtained dermal tissue fraction with collagen to give a cell suspension, and then storing the cell suspension in a frozen state to thereby kill hair follicle epithelial cells. It is also intended to provide a composition for regenerating hair follicle which contains hair papilla cells and epithelial cells, characterized in that the ratio of the hair papilla cell count to the epithelial cell count ranges from 1:10 to 10:1.
