Figure 6. — Induced pluripotent stem cells (iPSCs) were stained with the vital dye Dil, and serial sections were stained as indicated in Methods. Upper, from left to right, Dil, Cx43, and DAPI staining. The merged image (lower) is from an area containing Dil-stained cells intercalated between myocytes. Green=Cx43 (Connexin 43) staining, Blue=DAPI, Red–Orange=Dil. Arrows indicate Cx43 staining within the region occupied by Dil-stained cells. Red background is because of leaching of the Dil from the delivered iPSCs.
