Combining stem cells in myocardial infarction: The road to superior repair?

Med Res Rev 2021 Jun 11. Epub 2021 Jun 11.

Biomedical Research Institute (BIOMED), Department of Cardio and Organ Systems, UHasselt-Hasselt University, Agoralaan, Diepenbeek, Belgium.

Myocardial infarction irreversibly destroys millions of cardiomyocytes in the ventricle, making it the leading cause of heart failure worldwide. Over the past two decades, many progenitor and stem cell types were proposed as the ideal candidate to regenerate the heart after injury. The potential of stem cell therapy has been investigated thoroughly in animal and human studies, aiming at cardiac repair by true tissue replacement, by immune modulation, or by the secretion of paracrine factors that stimulate endogenous repair processes.
