The bHLH transcription factor Hand1 is essential for placentation and cardiac morphogenesis in the developing embryo. Here we implicate Hand1 as a molecular switch that determines whether a trophoblast stem cell continues to proliferate or commits to differentiation. We identify a novel interaction of Hand1 with a protein that contains an I-mfa (inhibitor(More)
The bHLH transcription factor Hand1 is essential for placentation and cardiac morphogenesis but how its developmental activity is regulated is largely unknown. We recently showed that Hand1 is sequestered in the nucleoli of rodent trophoblast stem (TS) cells by the I-mfa domain-containing protein HICp40 and that this is associated with their proliferation(More)
