• uke researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals.
  • The lab-grown tissue should soon allow researchers to test new drugs and study diseases in functioning human muscle outside of the human body.
  • Bursac and Madden started with a small sample of human cells that had already progressed beyond stem cells but hadn’t yet become muscle tissue. They expanded these “myogenic precursors” by more than a 1000-fold, and then put them into a supportive, 3D scaffolding filled with a nourishing gel that allowed them to form aligned and functioning muscle fibers.
