Characterization of preantral follicle clustering and neighborhood patterns in the equine ovary
PLoS ONE, 2022 Understanding the transition from quiescent primordial follicles to activated primary follicles is vital for characterizing ovarian folliculogenesis and improving assisted reproductive techniques.

-growth and Gene Expression of Porcine Preantral Follicles Retrieved by Different Protocols [PDF]
Asian-Australasian Journal of Animal Sciences, 2012 This study was conducted to determine how the isolation method of the porcine preantral follicles influenced the following follicular growth in vitro. Mechanical and enzymatical isolations were used for retrieving the follicles from prepubertal porcine ...

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 ...

Mechanisms of chemotherapy-induced human ovarian aging: double strand DNA breaks and microvascular compromise [PDF]
, 2011 The mechanism of chemotherapy-induced acceleration of ovarian aging is not fully understood. We used doxorubicin, a widely used cancer chemotherapeutic, in a variety of in vivo xenograft, and in vitro models to investigate the impact of chemotherapy ...

Neonatal exposure to xenoestrogens impairs the ovarian response to gonadotropin treatment in lambs [PDF]
, 2015 Bisphenol A (BPA) and diethylstilbestrol (DES) are xenoestrogens which have been associated with altered effects on reproduction. We hypothesized that neonatal xenoestrogen exposure affects the ovarian functionality in lambs.

Study of preantral follicle population in situ and after mechanical isolation from caprine ovaries at different reproductive stages [PDF]
, 1999 The purposes of this study were to estimate the population of caprine preantral follicles, and to evaluate quantitatively and qualitatively the efficiency of a specific mechanical method for the isolation of preantral follicles from mixed breed goats at ...

In Vitro Growth of Preantral Follicle and Maturation of Intrafollicular Oocyte from Aged Mice
Journal of Animal Reproduction and Biotechnology, 2019 This study aimed to recover the ovarian function through in vitro culture of preantral follicles from aged mice. First, we isolated the preantral follicles from ovaries of sixty-seven-week old B6D2F1 mice with decreased fecundity to know how many ...

Journal of Animal Reproduction and Biotechnology, 2019 The objective of this study was to establish an in vitro culture system for ovarian preantral follicles of B6D2F1. First, we optimized the in vitro preantral-follicle culture by culture duration, follicle stimulating hormone (FSH) type, and activin A ...
