Abstract
Coronary heart disease and various cardiomyopathys may cause myocardial damage, reducing the number of myocardial cells with complete functions. Cyclooxygenase 2 (Cox-2) has been reported participating in a variety of pathological processes, including tumor invasion and metastasis. In this study, we sought to explore the correlation of Cox-2 with MSCs proliferation, and migration. MSCs were transfected with pcDNA-Cox2 and NS-398 to promote or inhibit the expression of Cox2. Then, MTT, transwell, qRT-PCR and western blot were used to test the influence of Cox2 on cells proliferation, cells migration and cell viability of mesenchymal stem. The results show that Cox-2 promotes directional differentiation of myocardial cells and the overexpression of cox-2 can activate the key factors of JNK and ERK signaling pathway, promotes myocardial cell directional differentiation.
