research The roles of hepatocyte growth factor family members in androgen-regulation of human hair growth. A comparison of the expression of hepatocyte growth factor family members, HGF and MSP, and their receptors, c-Met and RON, in isolated hair follicles from normal and androgenetic alopecia (balding) scalp.
This study reported that paracrine factors, such as IGF-I and SCF, were reduced in balding hair follicles compared to non-balding ones, while inhibitory factors like TGFß-1 were increased, providing insights into the androgen action in hair follicles.
