Gap junctions and ovarian folliculogenesis [PDF]
Reproduction, 2002 Abstract Gap junctions are collections of intercellular membrane channels that allow adjacent cells to share small molecules (< 1 kDa). Gap junction channels are composed of connexins, a homologous family of more than 20 proteins.

Apoptosis during folliculogenesis in pigs [PDF]
Bioscientifica Proceedings, 2020 The number of female germ cells in pig fetuses decreases by 70% between day 50 after mating and day 300 after birth. Approximately 55% of antral follicles undergo degeneration (atresia) except during the 3 days before oestrus, when only 15% of the follicles survive to ovulate.

Select aspects of oogenesis and folliculogenesis
, 2013 The processes of oogenesis and folliculogenesis begin very early in foetal life and are continued until the end of the reproductive period. Despite the numerous research conducted, the mechanism which initiates the growth of primary follicles has not ...

<i>Saussurea lappa</i> enhances folliculogenesis by suppressing F2-isoprostane, TNF-α, and apoptosis in endometriosis mice. [PDF]
Open Vet JBackground: Endometriosis can disrupt folliculogenesis due to elevated levels of pro-inflammatory cytokines, free radicals, and the apoptotic response in granulosa cells. So it can cause fertility issues in women.

Defective folliculogenesis in female mice lacking Vaccinia-related kinase 1
, 2018 The Vaccinia-related kinase 1(VRK1), which is generally implicated in modulating cell cycle, plays important roles in mammalian gametogenesis. Female infertility in VRK1-deficient mice was reported to be caused by defective meiotic progression in oocyte ...
