Abstract:
Although the initial clinical trials of cardiac cell therapy have failed to demonstrate unequivocal clinical benefits, the accumulation of preclinical data gathered in parallel can now help us to understand the main causes of failures, while providing mechanistic insights that may be leveraged to improve the outcomes of subsequent clinical studies using cells or their secreted products. This review briefly describes the current status of clinical trials, discusses the potential mechanisms of action of the grafted cells, and the impact of this knowledge on the design of future studies, and finally draws some perspectives.
