Eugenol Improves Follicular Survival and Development During in vitro Culture of Goat Ovarian Tissue

Frontiers in Veterinary Science, 2022
This study evaluated the effects of different concentrations (10, 20, or 40 μM) of eugenol (EUG 10, EUG 20, or EUG 40), ascorbic acid (50 μg/mL; AA) or anethole (300 μg/mL; ANE 300) on the in-vitro survival and development of goat preantral follicles and

Impact of vitamin D3 supplementation on the in vitro growth of mouse preantral follicles. [PDF]

Clin Exp Reprod Med, 2021
Objective: We investigated the impact of vitamin D-3 (VD3) supplementation during mouse preantral follicle culture in vitro and the mRNA expression of 25-hydroxylase (CYP2R1), 1-alpha-hydroxylase (CYP27B1), and vitamin D receptor (VDR) in mouse ovarian ...

Review: Roles of follicle-stimulating hormone in preantral folliculogenesis of domestic animals: what can we learn from model species and where do we go from here?

Animal, 2023
The pituitary gonadotropin FSH is a glycoprotein critical for the development of ovarian follicles. Upon binding to its G protein-coupled membrane receptor located on the granulosa cells of ovarian follicles, FSH elicits a cascade of downstream ...

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 ...

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 ...

Effects of Culture Duration, Follicle Stimulating Hormone (FSH) Type, and Activin A Concentration on In Vitro Growth of Preantral Follicles and Maturation of Intrafollicular Oocytes

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 ...
