Researchers of Vienna University could succeed in making the first laboratory heart. As reported by Scientific, the researchers of Vienna University could make a compound, which changes fetal and adult fundamental cells to heart ones.
Primary stage of the said project has successfully been accomplished and at this stage, generated heart cells have had heartbeats inside laboratory dishes.   
This heart is made using DNA of the patient himself. There is a weak possibility to repair heart tissue by itself. However, using this chemical compound, this repair process will be accomplished. Presently, there are many patients all over the world, waiting for heart grafting.
