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...
