Microbubble and Ultrasound Therapies to Enhance Cartilage Repair and Regrowth
By combining low intensity pulsed ultrasound (LIPUS) with lipid coated microbubbles, researchers at GW increased differentiation of human mesenchymal stem cells (hMSCs) into cartilage. Existing treatments for damaged cartilage include autografts, allografts, and total joint replacement. Autografts suffer from donor site morbidity and insufficient donor...

4D-Printed Programmable Culture Substrate for Controlling Neural Stem Cell Growth
Neural stem cells (NSCs) exhibit great promise for treating neurodegenerative diseases and injuries. Treatments will rely on efficient proliferation and differentiation of NSCs into neurons with therapeutic characteristics. Static 2D and 3D microenvironment culture substrates fail to cater to the dynamic cell needs, resulting in sub-optimal, inefficient...

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...

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...
