The cells that they created were identical to healthy heart muscle cells. When these beating cells were transplanted into a rat, they started to make connections with the surrounding heart tissue.
Lead researcher Professor Lior Gepstein, said: "What is new and exciting about our research is that we have shown that it's possible to take skin cells from an elderly patient with advanced heart failure and end up with his own beating cells in a laboratory dish that are healthy and young - the equivalent to the stage of his heart cells when just born."
