A team of researchers in China has reported for the first time the live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line. This "chimeric" monkey is composed of cells that originate from two genetically distinct embryos of the same species of monkey. This has previously been demonstrated in rats and mice but, until now, has not been possible in other species, including non-human primates. The details of the research are reported November 9 in the journal Cell.

Gattacca here we come.
