Web1 Oct 2010 · Head muscle progenitors in pharyngeal mesoderm are present in close proximity to cells of the second heart field and show overlapping patterns of gene expression. However, it is not clear whether a single progenitor cell gives rise to both heart and head muscles. We now show that this is the case, using a retrospective clonal … Webthe second heart field and outflow tract as the result of an integration site position effect. Results:Here we show that the integration site of the A17-Myf5-nlacZ-T55 transgene lies upstream of Hes1, encoding a basic helix-loop-helix containing transcriptional repressor required for the maintenance of diverse progenitor cell populations overton golf course
