Application to humans still years away:

Researchers at the University of Minnesota recently reported in the journal Nature Medicine, that they were successful in creating a beating rat heart in a laboratory. This new breakthrough could lead to growing new human hearts and other organs to repair or replace damaged ones.

Dr. Doris Taylor, the head of the team that created the rat heart, said: “We just took nature’s own building blocks to build a new organ.” According to Dr. Taylor, scientists may be able to grow a human heart by taking stem cells from a patient’s bone marrow and placing them in a cadaver heart that has been prepared as a scaffold.
