Characterization of follicle populations in mare ovaries: From preantral to preovulatory follicles
(2015-01-01)
Introduction: The equine ovary is peculiar in that, unlike other mammalian ovaries, its germinal surface, where follicles and oocytes are found, is located at the organ’s central portion, while its conjunctive tissue and ...
First characterization of preantral follicles in the ovaries of adult alpaca
(Instituto de Investigaciones en Ciencias de la Salud, 2019)
Associated and independent comparisons between the two largest follicles preceding follicle deviation in cattle
(2003-02-01)
Follicle diameters and concentrations of follicular fluid factors were studied in the two largest follicles (F1 and F2) using F1 diameters in increments of 0.2 mm (equivalent to 4 h intervals) and extending from 7.4 to 8.4 ...

Localization of angiotensin receptor type 2 in fetal bovine ovaries
(Elsevier B.V., 2016-05-01)
In the ovary, angiotensin II (ANGII) acts through the type 2 receptor (AGTR2) to induce ovulation and may play a role in follicle atresia. In this study, we determined the expression of AGTR2 mRNA and protein during follicle ...
Morphological and quantitative evaluation of buffalo preantral follicles in different reproductive phases
(2010)
The objective of this research was to estimate the population of preantral follicles in prepubertal (P), adult (A) and pregnant (PR) female buffaloes, as well as to observe the different degeneration types and rates of ...
Morphological and quantitative evaluation of buffalo preantral follicles in different reproductive phases
(2010-01-01)
The objective of this research was to estimate the population of preantral follicles in prepubertal (P), adult (A) and pregnant (PR) female buffaloes, as well as to observe the different degeneration types and rates of ...
Follicle populations and gene expression profiles of Nelore and Angus heifers with low and high ovarian follicle counts
(2019-02-01)
The number of antral follicles counted (AFC) by ultrasound is associated with fertility in cattle. Cows with higher follicle count (HFC) have higher performance in reproductive-assisted technologies than cows with lower ...
PTEN and FOXO3 expression in the prenatal and postnatal human ovary
(Springer/Plenum Publishers, 2020-05)
Purpose: The objective of this study was to analyse the expression and cellular localization of FOXO3, pFOXO3 and PTEN throughout human ovary development both before and after birth. Methods: Foetal, pubertal and adult ...
