The article reveals the phenomenon that leads to “virgin births” in some species who are a source of embryonic stem cells.Researchers are obtaining human stem cells this way for the first time, and animal experiments suggest such cells are indistinguishable from normal stem cells. So destroying the embryos to obtain stem cells would avoid the ethical concerns that have led to restrictions or bans on embryonic stem cell research in many countries.A team led by fertility specialist David Twining at biotech firm Stemron of Maryland has grown parthenogenetic human embryos to the blastocyst stage, at which stem cells can be obtained. The next step is to get the cells to grow in culture indefinitely to obtain a stem cell line. According to Wininger it will possible to establish a bank of parthenogenetic stem cells that could provide cells to suit most individuals.
