The effects of electromagnetic fields on the number of ovarian primordial follicles: An experimental study

open access: yesKaohsiung Journal of Medical Sciences, 2015
The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study.

Germ–Somatic Cell Interactions Are Involved in Establishing the Follicle Reserve in Mammals

open access: yesFrontiers in Cell and Developmental Biology, 2021
Mammalian females are born with a finite reserve of ovarian follicles, the functional units of the ovary. Building an ovarian follicle involves a complex interaction between multiple cell types, of which the oocyte germ cell and the somatic granulosa ...

Evaluation of an alternative heterotopic transplantation model for ovarian tissue to test pharmaceuticals improvements for fertility restoration

open access: yesReproductive Biology and Endocrinology, 2022
Background Ovarian tissue cryopreservation and transplantation (OTCTP) is currently the main option available to preserve fertility in prepubertal patients undergoing aggressive cancer therapy treatments.

Senataxin: A New Guardian of the Female Germline Important for Delaying Ovarian Aging

open access: yesFrontiers in Genetics, 2021
Early decline in ovarian function known as premature ovarian aging (POA) occurs in around 10% of women and is characterized by a markedly reduced ovarian reserve.

Timely expression and activation of YAP1 in granulosa cells is essential for ovarian follicle development

open access: yesThe FASEB Journal, 2019
Although the role of the Hippo signaling pathway in development and tumorigenesis has been extensively studied in multiple organs, its role in ovarian follicle development remains largely unknown. Here, we report that Yes‐Associated Protein 1 (YAP1), the

Effects of hypoxia-preconditioned HucMSCs on neovascularization and follicle survival in frozen/thawed human ovarian cortex transplanted to immunodeficient mice

open access: yesStem Cell Research & Therapy, 2022
Background The massive loss of follicles in the early stage of ovarian tissue transplantation is considered a significant restriction to the efficacy of ovarian tissue cryopreservation (OTC) and transplantation (OT).

Human Ovarian Follicles Xenografted in Immunoisolating Capsules Survive Long Term Implantation in Mice

open access: yesFrontiers in Endocrinology, 2022
Female pediatric cancer survivors often develop Premature Ovarian Insufficiency (POI) owing to gonadotoxic effects of anticancer treatments. Here we investigate the use of a cell-based therapy consisting of human ovarian cortex encapsulated in a poly ...
