Scientists have grown embryos from stem cells to blastocysts that successfully implanted into the uterus
Creation of embryos without egg or sperm - life science news

Dutch scientists have created mouse embryos from stem cells, thus without fertilizing an egg with sperm cells. The embryos resemble natural ones in the sense that they implant into the uterus and initiate pregnancy. Using stem cells to create embryos is a radically new approach to study the first phases of development, infertility or the onset of diseases. Also, this new method can be used for screening of new medical techniques and pharmacological compounds for the treatment of disease.
