Uberon definition : The endocardial cushion is a specialized region of mesenchymal cells that will give
rise to the heart septa and valves[GO]. Swellings of tissue present between the endocardial
and myocardial cell layers that will give rise to the interstitial cells of the cardiac
valves[ZFA].;
Uberon related term : atrioventricular canal cushion; endocardial cushions;
Uberon Homology note : (Cardiac valve formation in vertebrates) In response to a myocardial signal, endocardial
cells at chamber boundaries take on a mesenchymal character, delaminate and migrate
into the cardiac jelly. There, they form an endocardial cushion that is later remodelled
into a valve.[well established][VHOG];
