摘要: Thyrotropic hormone (TSH) or cAMP accelerate the formation of follicular cavities in explanted thyroid gland 15-day-old rat fetus. Cytochalasin B vinblastine and nocodazole colchicine, which disorganize microfilamental microtubular structures respectively, inhibit completely block vitro-induced folliculogenesis. Exposure tissue to lumicolchicine, a structural isomer colchicine deprived antimicrotubular activity, does not activation folliculogenesis induced by TSH. These results are strong evidence for supposition that microfilaments microtubules involved TSH-stimulated mechanisms resulting Folliculogenesis requires integrity both microtubules.
