2017-01-13 · This method holds that if one pyknotic granulosa nucleus is seen in the largest cross section of a primary follicle, or three pyknotic cells are found in a larger follicle, it should be categorized as atretic.

FIGURE 4.8 . Ovaries of adult female Osteopilus septentrionalis (a–d,f) and Ambystoma mexicanum (e) with atretic follicles (AF). atresia strictly refers to the fail ure of a follicle to rupture or ovulate. More broadly, follicular atresia encompasses the fate or demise of all follicles except those destined for ovulation.

If playback doesn't begin shortly, try restarting your device Atretic follicles - Note that follicles may undergo atresia during any stage of development.

Circular RNAs (circRNAs) are thought to play essential roles in multiple biological processes, including apoptosis, an important process in antral follicle atresia. We aimed to investigate the potential involvement of circRNAs in granulosa cell apoptosis and thus antral follicle atresia. CircRNA expression profiles were generated from porcine granulosa cells isolated from healthy antral (HA

565,680,731 Follicular atresia is a complex hormonally driven process involving both putative “survival” factors, e.g., insulin-like growth factor-1, epidermal growth factor, basic fibroblast growth factor, E2, and activin; and putative atretogenic factors, e.g., tumor necrosis factor-α, GnRH, and androgens. 565,680,731 The respective action of each of these factors on atresia is dependent on the Size and type of follicle (normal or atretic) and morphology of the granulosa cells were correlated for each follicle with enzymatic activity and steroid content. The true preovulatory follicle was characterized by a pycnotic index which never exceeded 2.0/ml, whereas this index was significantly higher (5–10/ml) in early atretic follicles.

The study of follicular atresia is important not only in terms of understanding the normal process of follicular development, but also because it provides insight into

The atretic follicle is shown.

We also demonstrate that four of the identified SERPIN genes and proteins showed stage-specific localization in E 2 -active and E 2 -inactive follicles. Mature and atretic follicle, monkey, epon, 35x. To the left is a secondary (antral) follicle.A fluid filled space, the antrum, is developing.The fluid is known as the liquor folliculi and resembles plasma with a high concentration of steroids. Relating to atresia. SYN: atresic, imperforate.

In mammals, more than 99% of ovarian follicles undergo a degenerative process known as atresia. The molecular events involved in atresia initiation remain incompletely understood. The objective of this study was to analyze differential gene expression profiles of medium antral ovarian follicles during early atresia in pig.
