Females are born with a finite number of eggs that are steadily depleted throughout their lifetime. This reserve of eggs is selected from a much larger pool of millions of precursor cells, or oocytes, ...

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 ...

Oogenesis is the process by which an ovarian germ cell becomes a female gamete, an egg. A functional egg is capable of undergoing fertilization and giving rise to a developing embryo, and it should ...

The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers ...

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 ...

The first baby to be created from an egg that had been matured in the laboratory, frozen, thawed and then fertilized, has been born in Canada. Three other women are pregnant by the same process. The ...

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 ...

Human oocytes can last for up to 50 years—and a newly discovered metabolic pathway is key to this longevity. By Lauren J. Young Published Jul 22, 2022 2:45 PM EDT Get the Popular Science daily ...
