New “tissue Velcro” could help repair damaged hearts

October 2015   Comments

University of Toronto engineers have made assembling functional heart tissue as easy as fastening your shoes. Growing heart cells in a lab is not new, but the cells are often weak and lack the shape and supports of real cells. After growing heart cells around a silk suture in a one-dimensional line, the researchers grew tissue on a 3D scaffold with T-shaped posts that poke through the honeycomb holes in a second layer, much the same as Velcro. The assembled sheets start to beat almost immediately. The ultimate goal is to create artificial tissue to repair damaged hearts.
