The role of mitochondria in direct cell-to-cell connection dependent rescue of postischemic cardiomyoblasts.

In this in vitro study we induced ischemic injury on H9c2 rat cardiomyoblasts using the oxygen-glucose deprivation model (OGD). We monitored if the addition of healthy or mitochondria-depleted cells can save OGD treated cells from post-ischemic injury. We were able to significantly improve the surviving cell number of oxidatively damaged H9c2 cells by the addition of healthy cells to the culture.
