Question: Produced by developing primary follicles of the ovary: a) Estrogen. b) FSH. c) Progesterone. d) LH. e) Inhibin. Oogenesis: During female gametogenesis, an oocyte (ovum or egg) is produced. The female germ cells produce a primordial germ cell (PGC)...
1.A small, protective sac in the body. In most vertebrate animals, fertilized eggs develop in follicles located in the ovaries. In mammals, hair develops and grows from follicles in the skin. 2.A dry fruit that has a single chamber and splits open along only one seam to release its see...

2009). The ability to culture isolated follicles, however, has important implications for understanding early follicle development and has clinical relevance for the field of fertility preservation. Accordingly, there is a need to develop culture systems that support these early stages of follicle ...
Altogether, these studies indicate that somatic cells have the potential to develop into germ cells, and some mammalian species posses mitotically active germ cells in adult ovaries. Nevertheless, the paradigm that all primary follicles in adult mammalian females were formed during the fetal period of...

Millerichthys robustus is an annual fish whose ovarian follicles develop asynchronously, allowing daily reproduction from sexual maturity until death. The objective of this research is to describe, histologically, the processes of follicular atresia and regression of postovulatory follicular complexes (POC)...
Collagen IV is abundant around theca cells in the follicles. It is also found at lower-levels around the stroma and granulosa cells of the ovaries. Fibronectin is presented around the stroma and theca cells. As follicles develop, its abundance increases, except around the granulosa cells, where...
In organ culture of neonatal mouse5 ovaries, it was observed that significantly less primary follicles develop to the secondary6 stage. The objectives of this study were: 1) to compare ovarian follicular populations7 between organ-cultured neonatal mouse ovaries and freshly isolated age-matched ...
[23,93]. Respiratory mucosa from the trachea showed higher expression ofFCGRIIIA, modest levels ofFCGRIAandFCGRIIB, and rather low levels ofFCGRIIA. As expected for all epithelial models withoutlamina propriaand lymphoid follicles, expression levels of all FCGR decreased significantly (****p ≤...
