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 ...

The accurate distribution of chromosomes in an oocyte is essential for the correct transmission of genetic information to the next generation. Now, researchers from Kyushu University have demonstrated ...

High-resolution imaging reveals a large protein complex in egg cells that stores key developmental molecules. The structure ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...

A multi-institutional team of ovarian biologists and other reproductive specialists reports that putting an oocyte from an older mouse into the follicle of a young mouse can rejuvenate the oocyte, ...

Melina Schuh has been fascinated with ovarian germ cells, or oocytes, since she began her graduate studies in 2004. “[I] realized that only little was known about these important cells that are ...

Oocytes are immature egg cells that develop in almost all female mammals before birth. The propagation of future generations depends on this finite reserve of cells surviving for many years without ...

Tsukuba, Japan—In many mammals, a limited number of oocytes are responsible for producing the next generation. Oocytes grow within follicles, which consist of an oocyte and the surrounding granulosa ...
