Abstract:

BACKGROUND: Exercise-induced myocardial cell apoptosis and signal transduction and regulation mechanisms of sports medicine research have become an important issue, but remain poorly understood. Studies concerning the protective effect of bone marrow-derived mesenchymal stem cells (MSCs) to the exercise-induced myocardial cell apoptosis are rarely conducted.

OBJECTIVE: To analyze the protective effect of MSCs on myocardial apoptosis and the exercise-induced myocardial cell apoptosis, so as to explore the pathological cause of exercise-induced myocardial apoptosis and the protective effects of MSCs on myocardial cell apoptosis induced by hypoxia, ischemia, and oxidative stress.

METHODS: A computer-based online search of articles was performed in Medline database (1994-01/2009-09) with “Mesenchymal stem cells, Excessive exercise, Cardiomyocyte, Apoptosis” as key words and Chongqing PubMed Result NCBI database (1994-01/2009-09), Tsinghua Tong Fang database (1994-01/2009-06), with “bone marrow mesenchymal stem cells, over-training, myocardial cells, apoptosis” as key words.

RESULTS AND CONCLUSION: A total of 365 articles on stem cells and exercise-induced myocardial apoptosis were collected, including 120 Chinese and 245 English. Outdate, repetitive and similar studies were excluded, and 68 were included. MSCs display a protection to myocardial cell apoptosis induced by hypoxia, ischemia and oxidative stress caused by high-intensity or overload exercise training, thereby contributing to the improvement of heart function and early rehabilitation of exercise-induced myocardial tissue diseases.
