Ovary Development: Insights From a Three-Dimensional Imaging Revolution

Frontiers in Cell and Developmental Biology, 2021
The ovary is an indispensable unit of female reproduction and health. However, the study of ovarian function in mammals is hindered by unique challenges, which include the desynchronized development of oocytes, irregular distribution and vast size ...

Potential Functions of IGFBP-2 for Ovarian Folliculogenesis and Steroidogenesis

Frontiers in Endocrinology, 2018
Ovarian follicles, as transient structural and functional complexes with the oocyte and the associated cells, determine the female reproductive cycle and thus fertility. Ovarian function is subject to the strict control of hormones and growth factors and

Protective Mechanism of Luteinizing Hormone and Follicle-Stimulating Hormone Against Nicotine-Induced Damage of Mouse Early Folliculogenesis

Frontiers in Cell and Developmental Biology, 2021
Previous studies have shown that nicotine could impair the germ cell cyst breakdown and the primordial follicle assembly by autophagy. In this paper, we discovered that luteinizing hormone (LH) and follicle-stimulating hormone (FSH) could counteract the ...

Species-specific differences in follicular antral sizes result from diffusion-based limitations on the thickness of the granulosa cell layer

, 2013
The size of mature oocytes is similar across mammalian species, yet the size of ovarian follicles increases with species size, with some ovarian follicles reaching diameters more than 1000-fold the size of the enclosed oocyte.

Smad signalling in the ovary [PDF]

, 2006
has now been a decade since the first discovery of the intracellular Smad proteins, the downstream signalling molecules of one of the most important growth factor families in the animal kingdom, the transforming growth factor beta (TGF-beta) superfamily.

Alterations in Gene Expression and the Fatty Acid Profile Impact but Do Not Compromise the In Vitro Maturation of Zebrafish (Danio rerio) Stage III Ovarian Follicles after Cryopreservation

Animals, 2023
The vitrification of ovarian follicles is a strategic tool that may contribute to advances in aquaculture and the conservation of many important species. Despite the difficulties inherent to the cryopreservation of oocytes, some successful protocols have

Bridging Time Scales in Cellular Decision Making with a Stochastic Bistable Switch [PDF]

, 2010
Cellular transformations which involve a significant phenotypical change of the cell's state use bistable biochemical switches as underlying decision systems.
