Figure 2. FIB/SEM micrographs of y-iPSCs (a,b), ma-iPSCs (c,d) and a-iPSCs (e,f). Images have been electronically colored to highlight nuclei (in blue), mitochondria (in pink), and autophagosomes (in green). Arrowheads, gap junctions; asterisks, tight junctions; G, Golgi apparatus; RER, rough endoplasmic reticulum.
