3D Printing Blood Vessels Without Sacrificial Templates
Using novel bioactive ink for 3D printing, GW researchers create multi-layered vasculature. Large-scale artificial tissue implants for defect reconstruction require vascularization to avoid interior necrosis, but blood vessel printing remains challenging. Current 3D bioprinting methods for creating vasculature mainly utilize sacrificial templates to...

3D printed vascularized tissue scaffold with extracellular matrix triggered growth factor release
­Vas-Scaf” is a 3D bio-printed vascularized bone scaffold perfused with osteogenic and angiogenic growth factors. Artificial bone grafts lacking vascularization fail due to poor integration of new tissues with the host and death of interior bone tissues. Bone and blood vessel tissues require different support structures and different biochemical...
