Michael Cook*<\/a><\/p>\n

The controversy over three-parent embryos could soon be old hat. Writing in one of the world’s leading journals, one of Britain’s best-known bioethicists has outlined a strategy for creating children with four or more genetic parents. He calls it “multiplex parenting”.<\/p>\n

John Harris, of the University of Manchester, and two colleagues, C\u00e9sar Palacios-Gonz\u00e1lez and Giuseppe Testa contend in the Journal of Medical Ethics<\/a> (free online) that this is one of many exciting consequences of using stem cells to create synthetic eggs and sperm. (Or as they prefer to call them, in vitro generated gametes (IVG).)<\/p>\n

After the discovery of induced pluripotent stem cells in 2007, theoretically any cell in the body can be created from something as simple as a skin cell. Mice have already been born from sperm and eggs created from stem cells. Harris and his colleagues believe that the day is not far off when scientists will be able to do the same with humans. In their paper, they spin an ethical justification for this and outline some possible uses.<\/p>\n

First, is it ethical? Of course it is, so long as experiments on mice show that it is safe. After all, they write, this is already a much higher ethical bar than the one used for the first IVF babies. “If impractically high precautionary thresholds were decisive we would not have vaccines, nor IVF, nor any other advance. Nothing is entirely safe.” Besides, any children brought into the world are better off than if they never existed. . . [Full Text<\/strong><\/a>]<\/p>\n","protected":false},"excerpt":{"rendered":"
