Many heart patients in need of a transplant will die waiting for a new organ to become available.
If perfected on larger hearts it could create a potentially unlimited supply of needed organs and the researchers say use of a patients own stem cells would ensure that a bio artificial heart is compatible with his or her immune system.
In their experiments researchers removed the hearts of newborn lab rats and stripped them of their cells in a process called organ decellularization. Researchers at the university of minnesota seeking new treatments for heart disease have grown a beating rat heart in the lab by using stem cells.
Lead researcher doris taylor who heads the university of minnesotas center for cardiovascular repair says investigators were left with a white protein matrix shaped like a heart that contained conduits where the blood vessels had been.
What we were able to show is that we could take a previously dead heart that we removed all the cells from and really reanimate that with new cells she said.
