One of the things that makes heart disease so problematic is the fact that after a heart attack occurs, the scar tissue that replaces the damaged heart tissue isn’t capable of expanding and contracting – it doesn’t “beat,” in other words. This leaves the heart permanently weakened. Now, however, scientists from Harvard-affiliated Brigham and Women's Hospital (BWH) have developed artificial heart tissue that may ultimately provide a solution to that problem.
At the base of the material is a rubbery gel known as MeTro. It’s made from tropoelastin, which is the protein that gives human tissues their elasticity.
