The present study tested specific hypotheses regarding: (1) a stimulatory role of atretic follicles on differentiation of follicles of the next wave; (2) a stimulatory role of large follicles in F-gene-carrier Booroola ewes on differentiation of follicles of the same ovulatory cohort; and (3) an inhibitory role of the dominant follicle on differentiation of follicles of the same ovulatory cohort.

This is a normal process and several of these occur each month in a woman's body. If atretic follicles are retrieved in preparation for in vitro fertilization (IVF), they cannot be used for fertilization and transfer. Atretic follicles were found among follicles at all stages of development. The percentage of follicles with signs of atresia became larger as the size of the follicles increased. Only 2% of small follicles (Type 3b) showed signs of atresia, while all follicles greater than 1 mm in diameter (Type 8) were atretic. Atretic follicles are rare in ovaries of amphibians, compared to the extensive atresia found in mammalian ovaries (Norris & Lopez, 2005).
Atretic follicles <5 mm are either basal atretic or antral atretic, named on the basis of the location in the membrana granulosa where cells die first. Basal atretic follicles have considerable biological differences to antral atretic follicles. In follicles >5 mm, only antral atresia is observed.

Sometimes it is difficult to distinguish an atretic follicle from one in which the oocyte is poorly fixed. Macroscopic identification and steroidogenic function of atretic follicles in sheep. Moor RM, Hay MF, Dott HM, Cran DG. The degree of translucency, vascularization of the follicle wall and the integrity of the membrana granulosa, as seen under a stereoscopic microscope, were used to distinguish between non-atretic and atretic isolated follicles. 2014-01-18 · These follicle types also differ in the quality of their oocytes when cultured in vitro [ 16 ]. The atretic follicles were of the type called antral atretic [ 7, 8 ].

follicles to growing follicles is a critical part of follicular development or folliculogenesis . It is a process that begins gradually, almost imperceptibly after the formation of primordial follicles, and then continues throughout the reproductive life of the animal (Fortune et al., 1998; Oktem & Urman, 2010).
Atretic follicles are rare in ovaries of amphibians, compared to the extensive atresia found in mammalian ovaries (Norris & Lopez, 2005). FIGURE 4.8 . Ovaries of adult female Osteopilus septentrionalis (a–d,f) and Ambystoma mexicanum (e) with atretic follicles (AF).
Through the first 20 days of age, atresia occurred at a low but constant rate (Fig. 1b), consistent with a proportional decline in non-atretic follicle numbers during this time period (Fig. 1a). However, the incidence of atresia increased 2018-03-09 Cumulus cells (in the advanced atretic follicle) surrounding oocytes and adjacent granulosa layers retain the Cx43 protein, although there was only a sparse expression of Cx43 observed in the atretic follicle rzeczownik Dodatkowe przykłady dopasowywane są do haseł w zautomatyzowany sposób - nie gwarantujemy ich poprawności.
