Piero Anversa, Italian scientist and director of regenerative medicine at the Brigham and Women’s Hospital of Harvard University in Boston is ready to perform the first biological by-pass in history. This evening in Milan during a meeting called ‘Futuro della Sanita’ (The Future of Health), Anversa explained that he has identified human coronary stem cells able to develop into coronary artery tissue.
He said, “My dream is for someone to have a heart attack, come to the hospital, and return home healthy.” For that to occur, it will be necessary to reproduce muscle and the large coronary vessels.

A biodegradable tissue to repair hearts after a heart attacks or to cure congenital malformations. A tissue that acts like a porous, accordion-like medium onto which cardiac stem cells are ‘implanted’ has been created by scientists from the prestigious Massachusetts Institute of Technology in Boston (MIT). This “bioscaffolding” integrates perfectly with cardiac tissue and creates a biological “band-aid” that is slowly reabsorbed and repairs cardiac muscle.
Compared to similar previous attempts, explained George Engelmayr in “Nature Materials” magazine, the advantage of the “bioscaffolding” is that it faithfully mirrors cardiac tissue structurally and mechanically, and
