Abstract excerpt
RATIONALE: c-myb null (knockout) embryonic stem cells (ESC) can differentiate into cardiomyocytes but not contractile smooth muscle cells (SMC) in embryoid bodies (EB). OBJECTIVE: To define the role of c-Myb in SMC differentiation from ESC. METHODS AND RESULTS: In wild-type (WT) EB, high c-Myb levels on days 0-2 of differentiation undergo ubiquitin-mediated proteosomal degradation on days 2.5-3, resurging on days...
