In a recent issue of Science, Lei and Spradling (2016) uncover how germ cells differentiate into oocytes in mouse embryos. Mouse germ cells form cysts, in which sister cells nurse the developing oocyte by donating their organelles and cytoplasmic materials.

Combined Effect of Follicle–Follicle Interactions and Declining Follicle-Stimulating Hormone on Murine Follicle Health In Vitro1 [PDF]
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. To date, most research into follicle dominance has concentrated on its endocrine regulation, although ...

Hair Follicle Pigmentation [PDF]
Hair shaft melanin components (eu- or/and pheomelanin) are a long-lived record of precise interactions in the hair follicle pigmentary unit, e.g., between follicular melanocytes, keratinocytes, and dermal papilla fibroblasts. Follicular melanogenesis (FM) involves sequentially the melanogenic activity of follicular melanocytes, the transfer of melanin ...

Apoptosis in the Hair Follicle [PDF]
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 ...

Effect of androgen treatment during foetal and/or neonatal life on ovarian function in prepubertal and adult rats [PDF]
We investigated the effects of different windows of testosterone propionate (TP) treatment during foetal and neonatal life in female rats to determine whether and when excess androgen exposure would cause disruption of adult reproductive function ...
