Abstract:

BACKGROUND: C-kit+ cardiac stem cells with high self-renewal ability can specifically differentiate into cardiac structural cells, which are considered for the most promising stem cell type to completely repair myocardial regeneration in patients with ischemic heart disease and other end-stage heart diseases.
OBJECTIVE: By reviewing the discovery, origin, characteristics, research progress of cardiac stem cells in the treatment of patients with ischemic heart disease as well as the existing problems and possible solutions, to strengthen the understanding about the characteristics of the C-kit+ cardiac stem cells in order to better predict the biological behavior.
METHODS: A computer-based search of PubMed (2003-01/2014-06) was performed to collect articles about cardiac stem cells. The key words included “stem cell, C-kit+ cardiac stem cells, cardiac infarction”. Articles related to C-kit+ cardiac stem cells published recently or in high-impact journals were initially surveyed and finally 38 articles were included and summarized.
RESULTS AND CONCLUSION: C-kit+ cardiac stem cells have been confirmed to improve heart function and ventricular remodeling in animals, and recently SCIPIO phase I clinical studies have also confirmed that the C-kit+ cardiac stem cells could improve cardiac function and quality of life in patients with ischemic heart diseases. Although transplanted cells are found quickly lost and cannot repair fibrous scar, its beneficial effects on the heart
is not stopped with the loss of seed cells, but can persist for a long time, which is considered to be mainly related to paracrine effects of various cytokines. Currently, it has brought new hope for stem cell therapy to end-stage heart diseases, but the survival and differentiation of the stem cells after transplantation still to be further studied.
