چکیده انگلیسی
In this study, it was investigated how estrogens (17-β-estradiol, E2) affect the estrogen receptor (ER) expression and gene regulation of male versus female human scalp hair follicles in vitro. Anagen VI follicles from frontotemporal scalp skin were microdissected and organ-cultured for up to 9 d in the presence of E2 (1-100 nm). Immunohistochemistry was performed for ERβ-expression, known to be predominant in human scalp hair follicles, and for TGF-β2-expression (as negative key hair growth modulator), and E2-responsive genes in organ-cultured human scalp hair follicles (48 h, 10 nM) were explored by cDNA microarray, using a commercial skin focus chip (Memorec, Cologne, Germany). The distribution pattern of ERβ and TGF-β2-immunoreactivity differed between male and female hair follicles after 48 h culture. Of 1300 genes tested, several genes were regulated sex-dependent differently. The study reveals substantial sex-dependent differences in the response of frontotemporal human scalp hair follicles to E2. Recognition and systematic dissection of the E2-dependent gene regulation will be crucial for the development of more effective, gender-tailored management strategies for female versus male pattern balding.
