Induced Pluripotent Stem Cells (IMAGE) Salk Institute Caption This microscope image shows induced pluripotent stem cells (iPSC) from our closest living relatives. Skin cells from bonobos (pigmy chimps) were reprogrammed to pluripotent stem cells, an advance that allows scientists to study the differences between the neurons of humans and chimps. The colors show different aspects of the cells' molecular components.
