Patching up complex heart tissues after heart attacks can get very complicated with longer healing time. However, a 3D-printed cell patch might just do the trick a lot easier. Engadget reports that a team of researchers have used laser-based bioprinting to fit stem cells (based on adult human heart cells) to a matrix developed around a 3D scan of heart tissue’s native proteins.
These 3D printed cell patches can heal scarred heart tissues and replicate structures of regular heart tissues. The testing was done on a mouse heart and early results look promising. The researchers believe that human-scale patches might be viable in a few years and should aid recovery from heart surgery much better
