Aims: Limited regenerative potential of cardiomyocytes (CMs) causes irreversible changes in heart tissue during pathological processes. However bone marrow mononuclear cells (BM-MNCs) can migrate to this tissue, incorporate to the area of dead or missing myocytes, and improve the global heart function. The mechanism of BMMSCs’ incorporation and interaction with CMs is not clear. Our aim was to create an in vitro model which would enable to study the interaction of BM-MNCs with CMs and to make a microscopy description of these interactions.
Methods and Results: CMs were isolated from adult and newborn rats. BM-MNCs were isolated from bone marrow. BM-MNCs were added to the myocyte culture. Cell-to-cell adherence and Cx43 expression were evaluated by fluorescence microscopy, Ca2+ transients were evaluated in cardiomyocyte-BMC communication .. View More»
