Abstract

Stem cell therapy in patients with acute myocardial infarction promises a new exciting option. However, the long term fate of stem cells transplanted into myocardial is not clear. Molecular imaging play a vital role in tracking stem cells after intramyocardial delivery as well as in helping us understand the mechanisms of stem cell biology in vivo. In this review, we summarize the principles underlying four kinds of stem cells applied into myocardial infarction and the major tracking methods. Finally, we discuss that molecular imaging will be useful to the successful clinical implementation of this novel therapy.
