The numerous varieties of cells within the human physique are produced by the method of differentiation, wherein stem cells are transformed to extra specialised sorts. Presently, it’s difficult for researchers to regulate the differentiation of stem cells within the lab (in vitro). Of explicit curiosity are oocytes, that are feminine germ cells that grow to be eggs. Understanding their growth might have far-ranging impacts, from infertility remedy to conservation of endangered species. A brand new examine has efficiently induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with people. By establishing a tradition technique for inducing the differentiation of meiotic oocytes, the researchers aimed to make clear germ cell growth in each people and different primates.
