Combined Effect of Follicle–Follicle Interactions and Declining Follicle-Stimulating Hormone on Murine Follicle Health In Vitro1 [PDF]

open access: yesBiology of Reproduction, 2001
Follicle selection occurs throughout an adult female's reproductive life, with selected, dominant follicle(s) developing to the preovulatory stage whereas the remaining, subordinate follicles within the growing cohort instead undergo atresia and die.

Apoptosis plays an important role in many physiological processes, ranging from morphogenetic events to adult tissue homeostasis, and defects in its regulation contribute to many disorders. Here we review molecular mechanisms of apoptosis in the hair follicle (HF), whose cyclical growth pattern is repeatedly interrupted by apoptosis-driven involution ...
