Scientist advances prospect of regeneration in humans

In a study that builds on earlier research that identified macrophages as essential to regeneration in the axolotl, a highly regenerative salamander, a scientist has identified the source of these critical white blood cells as the liver. By giving scientists a place to look for pro-regenerative macrophages in humans, the discovery brings science a step closer to the ability to regenerate tissues and organs lost to injury or disease.
