Effect of coconut water and Braun-Collins solutions at different temperatures and incubation times on the morphology of goat preantral follicles preserved in vitro [PDF]

, 2000
Preservation of preantral follicles becomes very important to ensure follicle quality at the onset of cryopreservation or in vitro culture. However, for domestic animals, the ovarian donor of preantral follicles for in vitro studies is commonly ...

The stage-dependent inhibitory effect of porcine follicular cells on the development of preantral follicles

, 2014
The objective of this study was to examine the effects of follicular cells on the in vitro development of porcine preantral follicles. In Experiment 1, one preantral follicle alone (Trt 1) was cocultured with a follicle of the same size with oocytes (Trt

Annexin II mRNA expression in bovine oocytes during follicular development

Genetics and Molecular Biology, 2006
We investigated the expression of calcium-dependent phospholipid binding protein annexin-II (Ann-II) messenger RNA (mRNA) during preantral follicle development and in oocytes from antral follicles of different diameters (< 3 mm, 5 to 8 mm and > 8 mm ...

Mouse serum facilitates the expansion of the follicular cavity regardless of the estrous cycle phase

Journal of Ovarian Research
Objective In investigating the effect of alcohol intake on the in vitro development of preantral follicles, physiological differences across estrous cycle phases in mice probably affect the results; therefore, it is necessary to determine whether serum ...
