Abstract;FGF-5 inhibitors with FGF-5-antagonizing activity may be effective against hair loss, as these inhibitors suppress the transition of hair follicles from the anagen to catagen phase caused by FGF-5. We screened 24 substances for their FGF-5-antagonizing activity using both an FGF receptor-1c-transfected Ba/F3 cell line and the C3H mouse, and finally detected Sanguisorba Officinalis Root Extract (SO extract) as a reliable FGF-5 inhibitor. Topical application of SO extract elongated the anagen period in C3H mice. In addition, in a clinical study using 39 volunteers with hair loss, the SO extract significantly decreased the telogen/anagen hair ratio and the number of shed hairs. This extract showed a high degree of usefulness clinically. These findings suggest that FGF-5-antagonizing activity of SO extract observed in vitro and in vivo is closely related to its clinical effects. (author abst.)
