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

Stem 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).

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

Frontiers 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.

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

Frontiers 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 ...

Metabolic Cooperation in the Ovarian Follicle

Physiological Research, 2020
Granulosa cells (GCs) are somatic cells essential for establishing and maintaining bi-directional communication with the oocytes. This connection has a profound importance for the delivery of energy substrates, structural components and ions to the maturing oocyte through gap junctions.

Female reproductive aging is master-planned at the level of ovary.

PLoS ONE, 2014
The ovary receives a finite pool of follicles during fetal life. Atresia remains the major form of follicular expenditure at all stages since development of ovary.

Is there a relationship between ovarian reserve and blood groups in infertile patients?

Gynecology Obstetrics & Reproductive Medicine, 2019
Objective: Evaluation of ovarian reserve in infertile patients had become an important concept in assisted reproductive techniques (ART) success work-up. Recent studies reported an association between blood type and ovarian reserve. Therefore, the aim of

Prediction of the Spontaneous Estrus Expression Period Based on Large (≥10 mm) Follicle Numbers in Lactating Holstein Dairy Cows

Veterinary Sciences, 2023
The objectives of this study were (1) to investigate the distribution of large (≥10 mm) follicle numbers during the estrous cycle and (2) to compare the timing of the estrus expression period after the ovarian examination between cows with one large ...

Dynamic genome-scale cell-specific metabolic models reveal novel inter-cellular and intra-cellular metabolic communications during ovarian follicle development

BMC Bioinformatics, 2019
Background The maturation of the female germ cell, the oocyte, requires the synthesis and storing of all the necessary metabolites to support multiple divisions after fertilization.

Non-coding RNAs in the Ovarian Follicle [PDF]

Frontiers in Genetics, 2017
The mammalian ovarian follicle is the complex reproductive unit comprising germ cell, somatic cells (Cumulus and Granulosa cells), and follicular fluid (FF): paracrine communication among the different cell types through FF ensures the development of a mature oocyte ready for fertilization.

Ovarian antral follicle number and the amount of gonadotropin used in ovarian stimulation in polycystic ovarian patients.

مجلة كلية الطب, 2011
Background: Polycystic ovary syndrome is the most common cause of anovulation, and the number of antral follicles is of great importance in determining ovarian reserve, so identification of patients with diminished ovarian reserve help in choosing ...
