Low oxygen conditions while culturing rGOCs (reconstructed granulosa cell-oocyte complexes) increased oocyte diameters in vitro, and viable eggs were successfully produced using this method. Mature ...

Attempts to obtain eggs and offspring using oocytes in ovary have been made for keeping desirable traits in livestock, preserving human fertility, etc. Ovarian transplantation, one of those methods, ...

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 ...

One of the immutable truths about being alive is that we age. This happens at every level, down to our cells. When they divide, our cells copy our DNA into each new cell. But as the weeks, months, and ...

Oocytes are among the longest-lived cells. Scientists have been trying to understand what enables such longevity, because oocytes—like other nondividing, long-lasting cells—have a high risk of ...

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 ...
