The cells responsible for the salamander's famed ability to regenerate amputated limbs aren't pluripotent, as scientists have thought, a linkurl:study published online in Nature;http://www.nature.com/nature/journal/v460/n7251/abs/nature08152.html today reports. That's good news for regenerative medicine: If the mechanism salamander cells use for regrowing body parts doesn't depend on pluripotent stem cells, it may be easier than researchers have assumed to mimic that organism's regenerative stra
