After a decade of work, the two biologists have developed a way to turn mice’s skin cells into “pre-egg” and “pre-sperm” cells of sorts, Nature reports. The cells are actually called primordial germ cells, with “germ” here meaning eggs and sperm, not germs like the ones you wash off your hands after going to the bathroom.
Once implanted in the testes of infertile adult mice, the primordial germ cells turn into sperm that allow the mice to father healthy-seeming pups. When implanted into the ovaries of a female adult mouse, the primordial germ cells become eggs that researchers are able to fertilize in vitro and turn into pups.
