| Research Abstract |
Formation of the endocardial cushion mesenchyme in the atrioventricular(AV) canal is the essential morphogenetic step in cardiac valvuloseptal morphogenesis. Numerous studies demonstrated that BMP-2 signaling promotes mesencymal cells differentiation into pre-valvular fibroblasts.
In this study, we showed that BMP-2 induces expression of Notch1 and Notch pathway intermediates in the endocardial cushion mesenchymal cells(ECMC) aggregate culture. We also demonstrated that BMP-2 induces the valvulogenic phenotype including hyarulonan expression and cellular migration and inhibits expression of alternative mesodermal lineage markers in chick ECMC cultures.
