Researchers have created a 3D-bioprinted patch that can help heal scarred heart tissue after a heart attack. Scientists at the University of Minnesota have incorporated stem cells from a human heart in a matrix that began to grow and beat synchronously in the lab. The patch was implanted into a mouse following a simulated heart attack, resulting in significant increase in functional capacity. The researchers have begun developing a larger patch to test on a pig heart.
