For ICSI participants, cumulus cells stripped from oocyte will be collected for cumulus gene expression analyses regarding oocyte competence. Microdrops of oocyte culture media before the time of ICSI ...

This work will be of interest to general cell biologists and developmental biologists ... The oviductal wall was punctured using a 26G needle to collect cumulus-oocyte complexes in 20 μL potassium ...

an oocyte with one or multiple follicular cavities and multiple layers of granular cells as well as cumulus GC layer. Nuclei was visible in oocyte; cystic follicle, a big cavity with a thin layer of ...

Sterilized needles were used to release cumulus-oocyte complexes (COCs). Next, COCs were pipetted in and out several times with a mouth pipette under dissection microscope to remove the cumulus cells ...

Communication between oocytes and granulosa cells is essential for oocyte formation, dormancy, reawakening, and maturation. Researchers have demonstrated that a protein complex called the exocyst ...

Nuclear maturity may directly relate to the success rate of ICSI. Rienzi et al. [32] reported that 7.9% of cumulus-oocyte complexes contained germinal vesiclestage (GV) oocytes; 5.6% contained ...

A recent study from Tata Institute of Fundamental Research, Mumbai, India has revealed new details about how our cells clean up and recycle waste. This process, known as autophagy, is like a self ...

Fertilization is a complex and highly regulated process that involves a series of molecular interactions between sperm and oocytes. However ... Here we demonstrated that SPACA4 is a spermatogenic cell ...

In general, chemotherapy medications work by attacking cells or by preventing them from growing and dividing. Cancer cells tend to grow and divide rapidly and uncontrollably, and many chemotherapy ...
