When the female germline develops, oocyte growth is accompanied by many changes in gene expression, however, the regulatory networks that control this process have not been determined. Now, a group of ...
In a new study published in the journal Nature, researchers in Japan report that activating just eight genes for producing gene-controlling proteins is enough to convert mouse stem cells directly into ...
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 ...
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 ...
Human egg cells, called oocytes, have to last a long time. They are created before birth, and if they are healthy, they stay viable for many years before they might be fertilized. New research has ...
A core set of eight proteins can transform stem cells from mice into cells that look a lot like immature egg cells called oocytes. The egglike cells could not undergo meiosis to cut the total ...
Current animal cloning techniques require that a single diploid nucleus be introduced into an enucleated oocyte, which is then stimulated to restart the embryonic development program. Recent evidence ...
A type of epigenetic mark that ordinarily causes gene activation may instead facilitate gene silencing in oocytes, cells that must be kept in stasis throughout childhood if they are to have the ...
