ABSTRACT
BACKGROUND:
Bone marrow mesenchymal stem cels can secrete a variety of factors in the local lesion, and these factors can promote cel proliferation and inhibit cel apoptosis.OBJECTIVE:
To observe the curative effect of bone marrow mesenchymal stem cel transplantation on the aging heart of rats and to explore the possible mechanism of action.METHODS:
Thirty Sprague-Dawley rats were randomized into three groups normal blank group, model group and treatment group. Aging models were made in the latter two groups by injection of D-galactose. Rats in the treatment group were given alogeneic bone marrow mesenchymal stem cel injection, once a week, totaly four times. At 1 week after final injection, the heart tissues were sliced into sections to observe the pathological changes using hematoxylin-eosin staining. Western blot assay was used to detect the expression of basic fibroblast growth factor in the heart tissues. Real-time PCR was used to measure the expression of p53 mRNA in the heart tissues. RESULTS ANDCONCLUSION:
Bone marrow mesenchymal stem cel transplantation could improve the pathological morphology of the aging heart. Compared with the model group, the expression of basic fibroblast growth factor in the heart tissues was significantly higher in the treatment group (P < 0.05), but the mRNA expression of p53 was lower (P < 0.05). It is speculated that bone marrow mesenchymal stem cels can interact with heart cels to secrete basic fibroblast growth factor and reduce p53 mRNA expression, thereby playing a curative effect on the aging heart.
