Engineering organoids to recapitulate brain tissue
The ability to derive and manipulate pluripotent stem cells has opened up new avenues for modeling biological systems in both healthy and diseased conditions. In order to more fully recapitulate the tissue microenvironment with its cell-cell, cell-extracellular matrix, and cell-niche interactions, it is essential to transition stem-cell culturing from monolayers to 3D structures. Self-organization of... -
Human Organs-on-Chips
Clinical studies take years to complete and testing a single compound can cost more than $2 billion. Meanwhile, innumerable animal lives are lost, and the process often fails to predict human responses because traditional animal models often do not accurately mimic human pathophysiology. For these reasons, there is a broad need for alternative ways to... -
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... -
4D Printing of Shapeshifting Devices
Organisms, such as flowers and plants, have tissue compositions and microstructures creating dynamic morphologies that can shapeshift in response to changes in their environments. Researchers at the Wyss Institute have mimicked a variety of such dynamic shape changes like those performed by tendrils, leaves, and flowers in response to changes in humidity or temperature with... -
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...
