[Method] Cashmere goat primary hair follicles were cultured in serum-free Williams E media supplemented with different doses of 17 β-E2 (0, 0.1, 1.0, 10.0, 100.0 nmol/L), and their growth rates and morphological changes were observed. [Result] The growth rate of 0.1 nmol/L 17 β-E2 group was quite comparable with that of the control group(0 nmol/L), but the 17 β-E2 with concentrations of 1.0, 10.0 and 100.0 nmol/L displayed different degrees of inhibition on the growth of hair follicles. Different morphological changes of hair follicles could also be discovered in different concentration treatments. [Conclusion] The study laid a certain foundation for exploring the regulation mechanism of estrogen on growth of cashmere goat hair follicles.展开更多
