SCIENTISTS have created a beating heart in the laboratory in a breakthrough that could allow doctors one day to make a range of organs for transplant almost from scratch.
The procedure involved stripping all the existing cells from a dead heart so that only the protein “skeleton” that created its shape was left.
Then the skeleton was seeded with live “progenitor” cells, which multiplied and grew back over it, eventually linking together into a new organ. Such cells are involved in the formative stages of specialised types of tissue such as those found in the heart.
