Regenerate Heart

Mohammad Izadifar, a researcher at University of Saskatchewan (U of S) who also works with biomedical and chemical engineering, has been working on to combine engineering, 3D printing, and medicine to repair damaged hearts by regenerating heart muscle tissue. He is using a natural, algae-based hydrogel that’s biocompatible and won’t be rejected by the human body; the hydrogel is also biodegradable. The 3D Printed patch is theoretically believed to evolve into heart with regenerating blood vessels and tissues.
