One set of signal transduction components that has been studied in detail in mature, differentiated cardiomyocytes is the PKC isotype superfamily. However, while the function of each isotype is slowly being uncovered in adult cardiomyocytes, limited information persists concerning their function in the differentiation process of cardiomyocytes. To begin analyzing the function of specific PKC isotypes in the differentiation process, we employed an established model for differentiating ES cells into cardiomyocyte-positive embryoid bodies (EBs) in vitro. RT-PCR, Western analyses, and confocal microscopy all showed that the expression of specific PKC isotypes was significantly changed as ES cells differentiated into cardiomyocytes. More importantly, by using antagonists specific for each isotype we found that this change was a final step in the differentiation process. PKC beta and zeta downregulation served to promote differentiation (beating), while upregulation of PKC epsilon appeared to amplify differentiation (beating). Finally, melding classical tools (i.e., ionic exchange glass beads) with recently developed methods for differentiating ES cells creates a possible novel technique for investigating differentiation of ES cells into cardiomyocytes as well as other cell types."xsd:string |
