Extracellular mechanical forces drive endocardial cell volume decrease during zebrafish cardiac valve morphogenesis

ALT text: Ventral view of a beating, two-chambered embryonic zebrafish heart that expresses a foreign transgene that labels the extracellular matrix (ECM). There is a significant amount of ECM in cardiac valves of the atrioventricular canal (AVC). OFC= Outflow tract. To learn more about this, see⬇️ 🧪
