Figure 4.

Formation of intercellular connections after OGD. (A) Nanotubular network formation was observed among DiO-labeled cardiomyoblasts (green) and DiD-labeled MSCs (red) after 24 hours of co-culture. (B) MitoTracker staining (red) revealed active mitochondria in the nanotubular network (yellow arrows). (C) Time lapse pictures of the formation of a nanotube between a DiO-labeled cardiomyoblast (green) and DiD-labeled stem cell (red).
