Development of Gametes from Embryonic Stem Cells
Highlights From The Conjoint Meeting Of The American Society For Reproductive Medicine And The Canadian Fertility And Andrology Society, 19 October 2005 Researchers at Cornell reported the ability to generate new pluripotent stem cell lines from embryos which began not as a union of sperm and egg, but rather of an egg and an embryonic stem cell. The investigators found that the stem cells placed in the ooplasm of the egg underwent haploidization (lost half of their chromosomes) and acted as the male germ cell. The embryos that developed from that process were then used to develop a 2nd generation stem cell line. |
