Abstract:
BACKGROUND:Stem cel transplantation has incomparable superiorities in the treatment of cardiovascular diseases. But stem cel s have a very low efficiency to differentiate into myocardial cel s spontaneously, and there are many factors influencing stem cel differentiation. OBJECTIVE:To clarify the pros and cons of different sources of stem cel s in the treatment of myocardial infarction, to investigate the methods for improving the differentiation efficiency of myocardial cel s, optimal differentiation conditions and mechanism underlying exercise-induced stem cel mobilization and endogenous myocardial cel regeneration. METHODS:A computer-based search of CNKI and PubMed databases was performed by the first author for articles related to stem cel therapy for myocardial infarction and stem cel differentiation into myocardial cel s, exercise effect on stem cel proliferation and myocardial cel regeneration published from 1985 to 2015. The key words were“stem cel s, myocardial infarction, myocardial regeneration, cardiac cel , exercise”in Chinese and English, respectively. Final y, 54 articles were included in result analysis. RESULTS AND CONCLUSION:In recent years, a variety of chemical inducers and biological components have been used in the myocardial differentiation of stem cel s. Simulation of myocardial microenvironment and vascular cel growth factors are the main methods of inducing myocardial differentiation. Aerobic exercise-induced stem cel mobilization can induce ischemic cardiac angiogenesis and upregulate a variety of vascular endothelial growth factors so as to promote myocardial proliferation and repair. However, in-depth exploration is stil needed in the harvesting of stem cel s, transplant rejection, and regulatory mechanisms underlying the directed differentiation of stem cel s into cardiomyocytes.
