Repeated superovulation may affect mitochondrial functions of cumulus cells in mice
Controlled ovarian stimulation by exogenous gonadotrophins is a key procedure during the in vitro fertilization cycle to obtain a sufficient number of oocytes in humans. Previous studies demonstrated that repeated superovulation had deleterious effects on the ovaries. However, whether repeated superovulation adversely affects the mitochondrial functions of cumulus cells remains unclear. In this...
متن کاملP-221: Impact of Prunus Cerasus on The Expression of HAS2 in Cumulus Cells on Mice
Background: Cherries are an important source of phyto- chemicals, especially anthocyanin. They have many potent biological Properties such as antioxidant activity. Oxidative stress is mainly insert their effect through decreasing of cell proliferation and viability. Infertility problem affect more than 15% of young couples in different societies. Oocyte expansion plays an important role in fert...
متن کاملMitochondrial Dysfunction and Apoptosis in Cumulus Cells of Type I Diabetic Mice
Impaired oocyte quality has been demonstrated in diabetic mice; however, the potential pathways by which maternal diabetes exerts its effects on the oocyte are poorly understood. Cumulus cells are in direct contact with the oocyte via gap junctions and provide essential nutrients to support oocyte development. In this study, we investigated the effects of maternal diabetes on the mitochondrial ...

OBJECTIVE To investigate the role of the cumulus cells and the cumulus matrix in affecting the penetrability, morphology, acrosome reaction, and motility of human spermatozoa penetrating the cumulus oophorus. DESIGN Controlled experimental laboratory study. SETTING University gynecology unit. PATIENT(S) Women undergoing assisted reproduction treatment and men visiting the subfertility cli...
متن کاملproduction of cloned mice by nuclear transfer of cumulus cells
background: over the past several years, mammals have been successfully cloned by either the splitting of an early stage embryo or nuclear transfer of adult somatic cells (nt) into oocytes. although it has been 15 years since the generation of the first cloned mammals from somatic cells by nt, the success rate for producing live offspring by this technique is low regardless of the cell type and...
