Does the subepicardial mesenchyme contribute myocardioblasts to the myocardium of the chick embryo heart? A quail‐chick chimera study tracing the fate of the epicardial primordium

Abstract excerpt

Morris (J. Anat., 1976;121:47-64) proposed that the subepicardial mesenchyme might represent a continuing source of myocardioblasts during embryonic and fetal development. Recent studies have shown that the epicardium and subepicardial mesenchyme, and the coronary vasculature are all derived from a region of the pericardial wall, called the proepicardial serosa. In avian embryos, the cells from the proepicardial...
