Spatial distribution of preantral follicles in the equine ovary. [PDF]
PLoS ONE, 2018 Comprehensive studies on spatial distribution of preantral follicles in the ovary are scarce. Considering that preantral follicles represent the main ovarian reserve, harvesting of these follicles is crucial for the development/use of assisted ...

In Vitro Culture of Bovine Preantral Follicles: A Review [PDF]
Reproductive Biology and Endocrinology, 2014 Preantral follicles are the majority of the ovarian follicle population and their use as a source of homogeneous oocytes for bovine reproductive biotechnologies could result in a substantial advance in this field.

Light microscopical and ultrastructural characterization of goat preantral follicles [PDF]
Small Ruminant Research, 2001 Goat ovarian preantral follicles were morphologically and ultrastructurally described in this work. Primordial follicles are oocytes surrounded by one layer of squamous or squamouscuboidal granulosa cells; primary follicles have a single layer of ...

Effect of different culture systems and 3, 5, 3'-triiodothyronine/follicle-stimulating hormone on preantral follicle development in mice. [PDF]
PLoS ONE, 2013 The mechanical method to isolate preantral follicle has been reported for many years. However, the culture systems in vitro are still unstable. The aim of this study was to analyze the effect of the culture system of mice preantral follicles on the ...

Ultrastructure and viability of isolated bovine preantral follicles [PDF]
Human Reproduction Update, 1998 Techniques for the isolation of ovarian follicles and maturation of oocytes in vitro have enormous reproductive potential. Preservation of normal tissue function is vital. This study emphasizes the ultrastructure and viability of mechanically isolated bovine small (diameter 40-100 microm) preantral and large (140-450 microm) preantral/early antral ...

The spatiotemporal expression pattern of the bone morphogenetic protein family in rat ovary cell types during the estrous cycle. [PDF]
, 2003 In the mammalian ovary, great interest in the expression and function of the bone morphogenetic protein (BMP) family has been recently generated from evidence of their critical role in determining folliculogenesis and female fertility.

Expression of the neural cell adhesion NCAM in endocrine cells of the ovary [PDF]
, 1991 In the adult mammalian ovary morphogenesis and differentiation processes are under hormonal control and, thus, occur in a highly regulated way during the sexual cycle.
