Engineering tissues to rebuild bodies

Tissue engineering – a rapidly growing field revolutionizing how physicians treat injury and recovery, thanks to game-changing advances in engineering, materials science and biology. For instance, brain cells now grow across degradable scaffolds to restore function; nanoparticles seed stem cells directly into bone to regenerate marrow; and skin tissues roll out from 3-D printers. Organs-on-a-chip offer scientists and engineers the ability to experiment with new drugs and therapeutic approaches in safer, more controlled conditions to develop future treatments for liver, kidney or heart conditions and more. The National Science Foundation, through its Directorate for Engineering, has played a key role in the emergence of tissue engineering as a recognized field of activity, and continues to shape the future of regenerative medicine.
