Three monkeys a genetic mishmash

For the first time, scientists have created primates whose cells carry one of several sets of genetic instructions instead of one consistent assemblage of DNA. The three rhesus monkeys are chimeras, conglomerates of cells from up to six genetically different embryos.

Creating the monkey chimeras was much harder than achieving a similar result in mice, suggesting that embryonic stem cells from primates, probably including humans, are less flexible than their mouse counterparts. Those findings could have implications for regenerative medicine, which seeks t
