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 ...

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 ...

Researchers have succeeded in reconstructing the ovarian environment using mouse stem cells. While growing immature egg cells -- known as oocytes -- from stem cells has been possible, the process ...

Mechanistic model for MTOC maturation in GV oocytes. The MTOC (grey) activates near the oocyte cortex, which requires recruitment of CKAP5 and TACC3. After activation, MTOC migrates to the nuclear ...

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 ...

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 ...
