Building on previous efforts to create a platform for the extended study of primate embryos in cell culture, two new reports from the State Key Laboratory of Primate Biomedical Research, Kunming University of Science and ...
Scientists at the University of Cambridge working with the Weizmann Institute have created primordial germ cells - cells that will go on to become egg and sperm - using human embryonic stem cells. Although this had already ...
