Diabetic cardiomyopathy consists of a series of structural and functional changes. Accumulating evidence supports the concept that a cardiac stem cell compartment disease plays an important role in the pathophysiology of diabetic cardiomyopathy. In diabetic hearts, human cardiac stem/progenitor cells (CSPC) are reduced and manifest defective proliferative capacity. Hyperglycaemia, hyperlipidemia, inflammation, and the consequent oxidative stress are enhanced in diabetes: these conditions can induce defects in both growth and survival of these cells with an imbalance between cell death and cell replacement, thus favouring the onset of diabetic cardiomyopathy and its progression towards heart failure. The preservation of CSPC compartment can contribute to counteract the negative impact of diabetes on the myocardium. The recent studies summarized in this review have improved our understanding of the development and stem cell biology within the cardiovascular system. However, several issues remain unsolved before cell therapy can become a clinical therapeutically relevant strategy.
