【Abstract】 The heart is the first organ to form during embryogenesis. The specification of heart precursors is a result of multiple tissues and cell-cell interactions that involve temporally and spatially integrated programs of inductive signaling events. The functions of the major signaling pathways BMP/Dpp,Wnt/Wingless,FGF and Notch are summarized during early cardiogenesis in both vertebrate and invertebrate models. The crosstalk among inductive signaling pathways and the relationships between signaling and cardiogenic transcriptional regulators that cooperate to control cardiac induction is also discussed in this review.更多还原
