The differentiation of mouse embryonic stem(ES) cell into smooth muscle cells(SMC) may play a major role in cardiovascular development and under pathophysiological conditions. Therefore, in the present study, we have examined the differentiation of ES cells and its related gene expression. SMC differentiation was indicated by cellular morphology and time-dependent induction of dibutyryl adenosine 3,5-cyclic monophosphate(DBcAMP)and retinoic acid(RA) on smooth muscle -actin(), smooth muscle myosin heavy chain(SMMHC) gene expression. The control was undifferentiated ES cells(protein expressions represent 50-60kDaOct-4). The results of this study show that morphology of embryoid body and confirmation of expression by immunocytochemistry. Moreover, SMMHC and desmin expression was significantly increased by time dependent manner(5, 7, 15 days), in contrast to expression was slightly decreased on 15days. In conclusion, DBcAMP and RA stimulate mouse ES cells differentiation into SMC and enhanced , SMMHC and desmin expression.
