Phylogeny informs ontogeny: a proposed common theme in the arterial pole of the vertebrate heart
29 Oct 2010
Abstract excerpt
In chick and mouse embryogenesis, a population of cells described as the secondary heart field (SHF) adds both myocardium and smooth muscle to the developing cardiac outflow tract (OFT). Following this addition, at approximately HH stage 22 in chick embryos, for example, the SHF can be identified architecturally by an overlapping seam at the arterial pole, where beating myocardium forms a junction with the smooth...
