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.
She says eight days later the experimental organs began pumping liquid faintly.
The hope is that we have created a tool that will really make people think differently and provide an opportunity to create new options for tissue engineering and for patients who need organs said dr.
Within a few days dr.
In their experiments researchers removed the hearts of newborn lab rats and stripped them of their cells in a process called organ decellularization. Taylor says these ghost hearts or scaffolds were re populated by infusing them with progenitor cells that have a capacity for self renewal and differentiation much like stem cells.
