Old hearts get a new beat
p2pnet news | Off Topic:- "Scientists have turned old hearts into new by stripping out all their cells and then rebuilding them with new ones," says Times Online.
"The new hearts started showing muscular contractions after four days, and pumping after another four."
University of Minnesota researchers say their technique, which at this point uses rat and pig hearts, "could eventually provide a new source of human organs for transplant," according to the Financial Times, which has Doris Taylor, director of Minnesota’s centre for cardiovascular repair. saying, "The idea would be to develop transplantable blood vessels or whole organs that are made from your own cells."
"The researchers used a process known as whole organ decellularization, where essentially all the cells of a heart are removed, leaving only those that constitute the physical framework, the extracellular matrix or ’scaffolding’ between cells," says Medical News Today.
