Regenerating heart valves
The human heart beats approximately 35 million times every year, pumping blood into the circulation via four different heart valves. In more than four million people each year, heart valves fail for different reasons, including birth defects, age-related deteriorations and infections. At present, clinicians use either artificial prostheses or fixed animal and cadaver-sourced tissue to...
Ultra-Strong Flexible Biomaterials
Hydrogels are already being developed for use as scaffolds for tissue engineering, vehicles for drug delivery, actuators for optics and fluidics, and models for biological studies of tissue-supporting material called the extracellular matrix. But these water-rich polymer gels are weak; they rupture if stretched just a little, and they break easily compared with resilient biological...
Injectable Hydrogels for Better Drug Delivery
Wyss researchers have developed a new approach to delivering drugs and therapeutic cells using biocompatible and biodegradable hydrogels made of alginate, a naturally occurring polysaccharide from brown algae. Injectable hydrogels could greatly improve clinical ability to provide extended drug release and controlled delivery throughout the body or at targeted local sites. The method holds promising...
3D Bioprinting of Living Tissues
Progress in drug testing and regenerative medicine could greatly benefit from laboratory-engineered human tissues built of a variety of cell types with precise 3D architecture. But production of greater than millimeter sized human tissues has been limited by a lack of methods for building tissues with embedded life-sustaining vascular networks. In this video, the Wyss...
