Extract

Apoptosis is a physiologically active process whereby cells die in a programmed manner (Stenn et al 1993). Growth of hair occurs as a consequence of proliferation and differentiation of the epidermal cells in the bulb of the hair follicles. Reduction of hair growth or loss of follicle viability may arise from reduction in proliferation, and also from apoptosis of epidermal hair shaft-forming cells. Increases in apoptosis have been associated with reduction in expression of the apoptosis inhibitor bcl2 (Lindner et al 1997). Previous studies (Tahmasbi et al 1998) have shown that biotin deficiency reduced the viability of mohair follicles and thymidine uptake in vitro. The aim of this work was to investigate the presence of apoptosis and bcl2 in follicles which maintained growth or were quiescent following culture in media unsupplemented or supplemented with biotin.
