objective(s): the present day challenge is how to obtain germ cells from stem cells to treat patients with cancer and infertility. much more efforts have been made to develop a procedure for attaining germ cells in vitro. recently, human umbilical cord-derived mesenchymal stem cells (humscs) have been introduced with higher efficacy for differentiation. in this work, we tried to explore the eff...
Background:Differentiation of Embryonic Stem Cells into Oocyte-like cells in vitro is challenging. Successful derivation of oocyte from stem cells can provide an alternative source for curing ovogenesis problems. The current study aims to demonstrate a new protocol with two different types of media for differentiating embryonic stem cells (ESCs) into oocyte-like cells ...
Background: Cryopreservation of ovaries is an important technique in assisted reproduction technology. Physical forces like hydrostatic pressure have a pivotal role in reproduction systems. Due to changes in intrafollicular pressure during ovulatory process, this study designed to examine the effects of hydrostatic pressure on oocyte maturation and cell death in cumulus cells from cryopreserved...
Background and purpose: Follicular fluid (FF) is a rich source of compounds for the development of oocyte. Wharton's jelly mesenchymal stem cells (WJ-MSCs) have a same differentiation origin with primordial germ cells, therefore, WJ-MSCs could differentiate into oocyte-like cells (OLCs) in the presence of appropriate factors. The purpose of present study was to isolate WJ-MSCs and then investig...
the use of ovarian stimulation for infertility treatment is associated with side effects of ovarian hyperstimulation syndrome (ohss) and potential cancer risk. this is also true in high risk women such as those polycystic with ovary (pco) and polycystic ovarian syndrome (pcos). in vitro maturation (ivm) of oocytes was primarily developed to make ivf safe for women with pco and at high risk of o...

Background: Oocyte in vitro maturation success rate is still low in compareision to oocyte in vivo maturation. Thus prediction and improvement of oocyte competency are two critical issues in assisted reproductive technology. New insights into oocyte-cumulus cell regulatory loop may assist our optimization of in vitro maturation technique. Maturation and developmental competency of cumulus oocyt...
Background and Objective: Cumulus cells regulate oocyte maturation through bilateral communication during follicular growth. Expression of disintegrin-like and metalloproteinase with thrombospondin type I motifs-1 (ADAMTS-1) is essential for structural remodeling during the follicle growth, to maintain normal granulosa cell layers in the follicles. Since limited studies have been performed on t...
Pluripotent human amniotic fluid cells (HuAFCs) can differentiate into various types of somatic cell in vitro. However, their differentiation into oocyte-like cells has never been described to the best of our knowledge. In the present study, differentiation of E-cadherin+ and E-cadherin- HuAFC sub-populations into oocyte-like cells was induced via culture in medium containing bovine follicular ...
The aim of this study was to trigger the expression of genes related to oocytes in putative ovarian stem cells scraped from the ovarian surface epithelium of women with premature ovarian failure and cultured in vitro in the presence of follicular fluid, rich in substances for oocyte growth and maturation. Ovarian surface epithelium was scraped and cell cultures were set up by scrapings in five ...
