The optimized research of the in vitro culture of preantral follicles in mice. [PDF]

J Clin Lab Anal, 2020
AbstractObjectiveEfficiency of preantral follicle culture in vitro is low and is dependent on species, development stage, and follicle‐stimulating hormone (FSH) concentration. Here, we optimized the preantral follicle in vitro culture system in mice.MethodsThe primary follicles (PM follicles, 80‐100 μm diameter ) and early secondary follicles (ES ...

The impact of offspring and maternal obesogenic diets on adult offspring oocyte mitochondrial morphology in primordial and preantral follicles. [PDF]

PLoS ONE
Diet-induced obesity reduces oocyte quality mainly by impacting oocyte mitochondrial functions. Moreover, maternal obesity is associated with mitochondrial dysfunction in oocytes of their adult offspring.

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 ...

Characterization of the Population of Ovarian Preantral Follicles in Juvenile Six-Banded Armadillos Infected or Not by Mycobacterium leprae [PDF]

Veterinary Sciences
The objective of this study was to characterize and estimate the population of ovarian preantral follicles in juvenile six-banded armadillos. Pairs of ovaries from five armadillos were collected during a routine epidemiological survey of leprosis (three ...

Characterization of isolated late preantral and early antral equine ovarian follicles [PDF]

Reproduction and Fertility
Understanding how to effectively isolate a large number of healthy follicles is essential for increasing success rates in ARTs, such as in vitro culture and cryopreservation.

Single-cell transcriptome and cell-specific network analysis reveal the reparative effect of neurotrophin-4 in preantral follicles grown in vitro [PDF]

Reproductive Biology and Endocrinology, 2021
Background In-vitro-grow (IVG) of preantral follicles is essential for female fertility preservation, while practical approach for improvement is far from being explored.

DTPA disrupts development of preantral ovarian follicles in vitro

Reproduction and Fertility
Dietary zinc deficiency disrupts fertility in vivo by impairing oocyte and embryo development near ovulation. Acute treatment of newborn ovaries with a strong intracellular chelator (TPEN), which preferentially binds zinc, disrupts follicular development.

Cryopreservation and In Vitro Culture of Isolated Porcine Ovarian Follicles [PDF]

Veterinary Sciences
Cryopreservation of preantral follicles (PAFs) is a promising tool for gene conservation and fertility preservation. However, standardized protocols for the cryopreservation and in vitro culture of isolated follicles—particularly in pigs—are still ...

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
