Stem cells: Recycling the abnormal
Alan Colman1 & Justine Burley2
Abstract
Using human eggs in the quest to make donor-specific embryonic stem cells is controversial. A method developed in mice, if applicable to humans, could eliminate the need to obtain eggs for this purpose.
On page 679 of this issue, Egli et al.1 describe a promising method for generating embryonic stem-cell (ESC) lineages using the technique of somatic-cell nuclear transfer (SCNT). Conventional SCNT involves replacement of the nuclear genetic material of an unfertilized egg (oocyte), with that of a somatic (non-germ) cell.
