Abstract:

BACKGROUND: Stem cells possess the potential of differentiation into myocardium and vessels, which can be transplanted into myocardial ischemia parts for tissue repair and revascularization. Therefore, stem cell transplantation has emerged as a promising alternative therapeutic approach for the treatment of ischemic heart disease. However, the long-term survival and curative efficacy issue of stem cells remains a problem. The emergence of genetic modification in combination with stem cell transplantation for stem cell research provides a new way of thinking.
OBJECTIVE: To explore stem cell types for cardiac regeneration therapy, the selection of the therapeutic gene, the genes vectors and transplantation way and to overview the clinical application of gene-modified stem cells in the field of cardiovascular disease.
METHODS: A computer-based search of PubMed (2006-01/2013-12) was performed to collect articles about stem cells. The key words included “stem cells; genetic therapy; myocardial infarction; regenerative medicine; tissue construction”. Articles related to stem cells published recently or in high-impact journals were initially surveyed and finally 40 articles were included and summarized.
RESULTS AND CONCLUSION: The efficacy of stem cell transplantation may be significantly augmented by genetic modification. Bone marrow mesenchymal stem cells are one of the most widely used seed cells currently. The anti-apoptosis, pro-angiogenic, anti-inflammatory genes mediated by the adeno-associated virus and adenovirus were transfected into stem cells, so that the curative effect of stem cell transplantation will be significantly increased. Genetically modified stem cell transplantation has the potential application in a variety of clinical diseases, including myocardial infarction, but its long-term safety remains to be further studied.
