One of the problems with heart attacks (as if there weren’t enough already) is that when the heart heals afterwards, it grows scar tissue over the part of the heart that was damaged. That scar tissue never does become beating heart tissue, so it leaves the heart compromised for the rest of the patient’s life. There may be hope, however, as scientists from the University of Minnesota have created a new patch that allows the heart to heal more completely.
First of all, yes, this has been done before. We have already seen experimental “heart patches” from places like the University of Tel Aviv, Brown University and MIT, which allow the heart to heal with a minimum of scar tissue growth.
One of the things that makes this latest patch unique is the fact that it’s 3D-bioprinted out of structural proteins native to the heart. It takes the form of a scaffolding-like matrix, which is subsequently seeded with cardiac cells derived from stem cells. The result is a patch of material, similar in structure and material to heart tissue, containing actual functioning heart cells – as opposed to inert scar tissue.
