Agining Differences in Induced Neurons (IMAGE) Cell Press Caption This image shows differences between neurons from old and young people only when they directly convert skin cells (left panel) into so-called induced neurons (iN; right panel). Aging differences are erased, however, when cells transit the induced pluripotent stem cell (iPSC) state. Credit Jerome Mertens and Fred Gage Usage Restrictions Credit Required.
