Abstract

Embryoid bodies were prepared from mouse embryonic stem cells expressing exogenous EGAM1C to analyze their ability to differentiate toward terminally differentiated cell types. The generation of cardiomyocytes was severely suppressed in Egam1c transfectants without upregulation of Nkx2-5, a crucial gene for cardiomyogenesis. These results indicate that EGAM1C is capable of affecting terminal differentiation in mouse embryonic stem cells.
