| sanju5 Total Posts: 138 | Posted: Sat Dec 22, 2007 03:25 pm Cardiac jelly - This acellular secretion of the myocardium plays a central role in septation of the heart and formation of the atrioventricular canals. During the early stages of heart development, the cardiac jelly comprises most of the thickness of the heart wall. As the heart differentiates, however, the cardiac jelly disappears and myocardium soon accounts for the major proportion of the heart wall |

| sanju5 Total Posts: 138 | Posted: Sun Dec 23, 2007 06:22 am neerubisht - any references ?? Here is something from Hurst's The Heart - Valentin Fuster - Formation of the cardiac tube is a complex morphogenetic sequence. Initially, primitive, bilateral heart tubes form from lateral plate mesoderm and each contains an inner layer of endocardium, a middle layer of cardiac jelly, and an outer layer of myocardium... Prior to looping, the acellular space between the myocardium and endocardium in the heart is filled with a deformable extracellular matrix. This "cardiac jelly" forms prior to cardiac tube fusion... The primoridal endothelial cells destined to form the endocardium interact and migrate through this matrix ... |
