Abstract:

BACKGROUND: Cardiac stem cells transplanted to the myocardial infarction area can effectively improve ventricular remodeling and promote heart function. But the survival rate of transplanted cells is lower in the infracted area under hypoxic microenvironment. Hypoxia inducing factor 1 alpha under anoxic conditions can stably express, and meanwhile increase the activity and survival ability of myocardial cells.
OBJECTIVE: To elaborate the research progress in hypoxia inducing factor 1 alpha-transfected cardiac stem cells for treatment of myocardial infarction from the following aspects: cardiac stem cell characteristics, mechanism underlying myocardial protection of hypoxia inducing factor 1 alpha, selection of carriers and transplantation approach.
 METHODS: A computer-based search of CNKI and PubMed was performed for articles related to cardiac stem cells and hypoxia inducing factor 1 alpha published from January 2000 to January 2015. The keywords were “cardiac stem cells, hypoxia inducible factor 1(HIF-1a), gene delivery” in Chinese and English, respectively, which appeared in the title and abstract. Finally, 37 relevant articles were enrolled in result analysis.
RESULTS AND CONCLUSION: Several studies have confirmed that hypoxia inducing factor 1 alpha can improve the survival rate of cardiac stem cells under anoxic conditions. Increasing evidences from animal experiments have shown that cardiac stem cells and hypoxia inducing factor 1 alpha exert protective and repairing effects on myocardial infarction. Currently, there is no successful report about hypoxia inducing factor 1 alpha gene transfection of cardiac stem cells, but relevant studies are proceeding. Gene modified cardiac stem cells are expected to be widely used in clinic.
