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 ...

DLGAP5 is proposed as a causal gene related to oocyte meiosis disorder for the first time. It expanded the current spectrum of pathogenic genes responsible for the phenotype of oocyte maturation and ...

Age may adversely affect women's fertility by impairing levels of RNA molecules which in turn alter the function of genes involved in key biological pathways during the final maturation stage of a ...

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 ...

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 ...

Methods have been developed in the past to assess spontaneous and induced chromosomal aneuploidy in germ cells and in early pre- and postimplantation mammalian embryos. Some of these methods yield ...

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 ...
