Is the Myofibrillarlytic Myocyte a Forme Fruste Apoptotic Myocyte?

The present study demonstrates that the majority of MFL cells are apoptotic and are associated with upregulation of caspase 3. Simultaneous upregulation of Bcl2 represents a survival effort in these myocytes. This is consistent with the review of the literature that MFL cells are viable, persist in myocardium for long time and may be functionally reversible. Evidence for concurrent apoptosis and survival instinct represent a conceptual paradox and suggests that myocytes undergoing apoptosis should be amenable to reconstitution of function.
