ABSTRACT
AIM:
To investigate the influence of bone marrow stromal cells (BMSCs) on the anoxia cardiomyocyte apoptosis.METHODS:
Using the anaerobic culture apparatus, the apoptosis of the cardiomyocytes, the BMSCs alone and co-cultured with each other were detected by morphological observation, PI staining flowcytometry, electrophoretic gel mobility analysis of DNA fragmentation. Western blotting was used to detect Bax and Bcl-2 protein expression.RESULTS:
Compared with control, the BMSCs were unsensitive to anoxic cultured while the anoxic cardiomyocytes were prone to apoptosis. Apoptosis of cardiomyocytes was increased significantly, detected by PI staining and agarose gel elestrophoresis showed “DNA ladder”. However, when anoxia cardiomyocytes co-cultured with BMSCs, apoptosis cells were decreased, “DNA ladder” disappeared and the expression of protein Bax was also decreased.CONCLUSION:
Bone marrow stromal cells prevent the anoxia cardiomyocytes from apoptosis, probably by suppressing the expression of Bax protein.
