Cx37, Cx40, and Cx43 are comparably localized and obvious gap junction plaques are largely absent in iRin37-F, Rin40, and Rin43 cells. Shown are iRin37-F (A–C), Rin40 (D–F), and Rin43 (G–I) cells. Cx-specific labeling is shown in A, D, and G and as overlays (pink) with Hoechst nuclear stain (blue) in B, E, and H; phase contrast images of immunostained fields are shown in C, F, and I. Scale bar represents 20 μm and applies to all panels.
