The aim of this review is to summarize the interactions between the oocyte and its surrounding granulosa cells which are involved in the control of oocyte growth or apoptosis as well as those playing a key role in the ability of the oocyte to undergo nuclear (resumption as meiosis to reach the MII stage) or cytoplasmic maturation (ability to fertilize and develop to the blastocyst stage). The r...

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 ...

Introduction: In vitro maturation and development of immature oocytes, as an artificial reproduction technique, is useful especially in women who are affected by cancer and polycystic ovary syndrome. Despite using many types of in vitro media, an appropriate environment has not been reported yet. Present study was designed to assess the effect of heated human follicular fluid (hHFF), which is s...

Developing a culture system for preantral follicles has important biotechnological implications due to the potential to produce a large number of oocytes for embryo production and transfer. To accomplish this goal, the present study was aimed to culture preantral follicles in the presence of different media, sera and FSH concentrations. Six-week-old preantral follicles (95 ± 5 µm) were cultured...

While today it is universally acknowledged that COVID-19 has generated immense challenges for businesses and societies worldwide, public perceptions varied significantly at the time of pandemic’s initial appearance, even among democratic with comparable media systems. The growing scholarship on grand societal in management organization studies, however, tends to neglect social construction issu...

in traditional medicine, mentha spicata is widely used for many diseases, especially in  digestive system. it has anti-androgenic effects thus can be used by women experiencing polycystic ovary syndrome (pcos). also, it has shown to possess antioxidant properties. although beneficial, studies have shown its detrimental effect on some tissues. the present study was carried out to determine the e...
