A protein known as MPS1 helps to ensure that a key process during cell division of oocytes—unfertilized egg cells—occurs in a timely manner, RIKEN biologists have discovered. This finding in mice may ...

Patients with a poor ovarian response (POR) are more likely to return to use previously vitrified oocytes, according to a study published online Jan. 2 in JAMA Network Open. Yuval Fouks, M.D., M.P.H., ...

The accumulation of misfolded or damaged proteins in long-lived, non-dividing cells like neurons are linked to neurodegenerative diseases like Alzheimer's. A study now finds that the build-up of these ...

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 ...

ELVAs pictured under a microscope. The ‘superorganelle’ roams the cytoplasm, capturing and holding onto toxic protein aggregates to protect oocytes from their toxic effects. Oocytes are immature egg ...
