According to BBC, Harvard scientists have succeeded in engineering a fully functional cardiac muscle. During the experiment, they identified which heart stem cells produce muscle cells, fat tissue cells and the cells of cardiac conduction system.
The scientists used the fluorescence method. Then, they could build the prototype of heart using cells as if they were Lego bricks, and waited until cells completed differentiation. The result was structurally correct heart muscle that was fully functional.
Scientists believe this was another step to engineer an artificial heart.
