Acoustically patterned hepatic lobule-like units for vascularized artificial liver

Engineering a transplantable artificial liver requires reconstituting the hepatic lobule, whose densely cellular parenchyma is organized around a hierarchically branched vascular network. Achieving high cellular density and hierarchical vascularization within a single fabrication step remains a major challenge. Here, we present an ultrasonic standing wave (USW)-based strategy that concurrently…
