Different cell death types determination in juvenile mice ovarian follicles
Follicular atresia is a phenomenon that leads to evacuation of the ovary from the oocytes and the occurrence of menopause. The contribution of various types of cell death in atresia at different follicular developmental stages requires extensive investigation. In this study, we evaluated 3 types of programmed </...
متن کاملComposition and morphology of the follicular basal lamina during atresia of bovine antral follicles.
The fate of the follicular basal lamina during atresia was investigated using bovine follicles, in which different follicle phenotypes have been observed. These phenotypes include: healthy follicles with rounded basal granulosa cells with an aligned basal lamina or follicles with columnar basal granulosa cells with a basal lamina of many loops (loopy), and atretic follicles in which either the ...

متن کاملOocyte-granulosa-theca cell interactions during preantral follicular development
The preantral-early antral follicle transition is the penultimate stage of follicular development in terms of gonadotropin dependence and follicle destiny (growth versus atresia). Follicular growth during this period is tightly regulated by oocyte-granulosa-theca cell interactions. Formation of the theca cell layer is a key event that occurs during this transitional stage. Granulosal factor(s) ...
متن کاملبیان متمایز دو واریانت مختلف Survivin در مراحل تکوینی فولیکولهای تخمدانی موش
Introduction & Objective: Survivin is one of the new characterized members of the inhibitor of apoptosis proteins that shows widespread expression in embryonic and tumoric tissues. The aim of this study was to evaluate the expression of Survivin variants in different stages of follicular development in mouse ovary. Materials & Methods: This experimental study was carried out on immature fema...
