The New York Times > Health > Tracking the Uncertain Science of Growing Heart Cells
Muito interessante...
As motivações dos cientistas e dos médicos são diferentes "indeed"... inclusiva as de ordem $$$$... onde e para quem vai o dinheiro da inovação, se para os laboratórios ou para os médicos que realizam o procedimento (transplante de medula), também é um ponto em disputa aqui?
Acho que eu torço para o transplante de medula.

n April 2001, researchers from the New York Medical College and the National Institutes of Health announced electrifying news for heart surgeons and their patients: stem cells from bone marrow, injected into the damaged hearts of mice, had morphed into the special cardiac muscle cells that the body cannot replace after a heart attack.

The researchers held out the hope that the procedure could be applied to people, too. The findings underlined a basic premise of stem cell therapy, that it will work before the cells and their elaborate control systems are fully understood - just put stem cells in the right place in the body, and they will do the rest.

But four years later, the treatment has yet to demonstrate whether it will fulfill its promise. And it has touched off a sharp difference of views among clinical doctors as to whether the therapy is ready to be taken to people.
