Scientist say they have managed to turn patients' own skin cells into healthy heart muscle in the lab.
Ultimately they hope this stem cell therapy could be used to treat heart failure patients....
In the latest study, the team in Israel took skin cells from two men with heart failure and mixed the cells up with a cocktail of genes and chemicals in the lab to create the stem cell treatment.
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.
