    【Abstract】 AIM: To investigate the regenerative conditions for hair follicle transected and to explore the location of hair follicle stem cells. METHODS： Hair follicle regeneration was observed by culturing the hair follicles transected at different sites (hair bulb, lower 1/3 part and 1/2 part). RESULTS： A new hair bulblike structure formed when hair follicles were transected at the hair bulb or the lower 1/3 extremity. The hair follicles continued to grow, the average growth length of the upper part of them was 078 mm and 067 mm and the growth rates were 75% and 70%, respectively. But only 125% of the hair follicles continued to grow when they were transected at their lower halves, which showed a significantly low growth rate compared with that of the other 2 groups(P< 001). CONCLUSION： Hair follicles can regrow and a new hair bulb can regenerate when they are transected at a certain site. The hair follicle stem cells are located in their upper portion of the hair follicles. ......
