title: Coordinating morphogenesis: epithelial integrity during heart tube assembly.
abstract: Formation of the embryonic heart tube requires the medial migration and merger of bilateral precursor populations. A new study of zebrafish cardiogenesis published in this issue of Developmental Cell indicates that precursor migration involves formation of a coherent epithelium and that fibronectin plays an important role in maintaining cardiac epithelial integrity.
