American monkey stem-cell work heading to UK humans
This week, Nature released a paper reporting the first embryonic stem cells made from an embryo cloned from an adult monkey. Next week, researchers in the UK hope to try the same thing with humans. The Oregon-based monkey team needed just over 300 monkey oocytes to make two monkey embryonic stem cell lines. The researchers at the University of Newcastle upon Tyne expect to have twice that number of freshly collected oocytes from women seeking fertility treatments.
