Abstract:

BACKGROUND: Bone marrow mesenchymal stem cell transplantation can effectively improve decreased cardiac function caused by heart failure, but there is a lack of research about the effect in bone marrow mesenchymal stem cell transplantation on cardiac function in heart failure induced by cardiomyopathies.
OBJECTIVE: To explore the effect of bone marrow mesenchymal stem cell transplantation on cardiac function in patients with cardiomyopathies accompanied by heart failure.
METHODS: Totally 40 Sprague-Dawley rats were enrolled, and bone marrow mesenchymal stem cells were isolated from 10 rats, and the remaining rats were equivalently randomized into normal, model and stem cell transplantation groups. Then rats in the model and stem cell transplantation groups were given intraperitoneal injection of hydrochloric acid doxorubicin to prepare cardiomyopathy-induced heart failure models. At 7 days after modeling, the stem cell transplantation group was treated with bone marrow mesenchymal stem cells through intravenous transplantation, and the model group was treated with equal amount of DMEM medium. Four weeks later, cardiac function of each rat was detected, and the cell survival and differentiation were observed by immunofluorescence method.
RESULTS AND CONCLUSION: At 4 weeks after transplantation, compared with normal and stem cell transplantation groups, the left ventricular systolic pressure and maximum rise/fall rate of left ventricular pressure were significantly decreased, but the left ventricular end diastolic pressure significantly increased in the model group (P < 0.05). And there was no significant difference between the normal group and the stem cell transplantation group (P > 0.05). High and dense fluorescence intensity was observed in the host myocardium immediately after transplantation. Subsequently, the fluorescence intensity and density decreased at 4 weeks, but the cell migration could be found, and some cells expressed cardiac troponin T. These results show that intravenous transplantation of bone marrow mesenchymal stem cells can improve cardiac function in rats with heart failure due to cardiomyopathies. Besides, the transplanted cells can survive in the host, and differentiate into cardiomyocyte-like cells.
