A protocol to isolate and qualify purified human preantral follicles in cases of acute leukemia, for future clinical applications

Journal of Ovarian Research, 2018
Background Autotransplantation of cryopreserved ovarian cortex can be associated with a risk of cancer cell reseeding. This issue could be eliminated by grafting isolated preantral follicles. Collagenase NB6 is an enzyme produced under good manufacturing

Cryopreservation of Preantral Follicles

, 2018
In mammals, the total number of female germ cells is already established by the time of birth, meaning that no mitosis will take place in oogonias thereafter. Their cryostorage, therefore, depends on ovarian tissue manipulation.

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.

Preantral follicle population and distribution in the horse ovary

Reproduction and Fertility, 2022
Characterization of the ovarian preantral follicle population is a necessary step to improve understanding of folliculogenesis and ovarian physiology. Therefore, in the present study, the preantral follicle population in the equine ovary in young and old

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 ...

Androgen stimulates growth of mouse preantral follicles in vitro: Interaction with follicle-stimulating hormone and with growth factors of the TGFβ super family [PDF]

Endocrinology, 2017
Androgens are essential for the normal function of mature antral follicles but also have a role in the early stages of follicle development. Polycystic ovary syndrome (PCOS), the most common cause of anovulatory infertility, is characterized by androgen ...

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 ...

Structure of preantral follicles, oxidative status and developmental competence of in vitro matured oocytes after ovary storage at 4 °C in the domestic cat model

Reproductive Biology and Endocrinology, 2018
Background Storage conditions during transportation of explanted ovaries are a critical step in setting up fertility preservation protocols in both animal and human fields.
