Increased expression of gap junctions in cardiomyocytes grown on CNTs scaffolds. (A) Neonatal cardiomyocytes grown on CNTs (MWCNT, left) or on control gelatin substrate (right) stained for connexin 43 (red), sarcomeric Alpha-Actinin (green), and counterstained with DAPI (blue). Bars: 50 μm. (B) The expression of connexin 43 (gap-junctions) after 1, 2, and 3 days culturing is increased in cultures grown on the CNTs scaffold. Reprinted with permission from Martinelli et al.
