In small follicles, the wall is lined with a narrow layer of tightly packed small, cuboidal cells separated from the thecal tissue by the basal lamina.

follicle atresia was conducted and compared with the numbers of non-atretic follicles lost over time. 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.
