Paolo Macchiarini has long been hailed as both a superstar surgeon and a revolutionizing researcher in the world of regenerative medicine. When he performed the world's first transplantation of a synthetic trachea seeded with stem cells in 2011, it seemed that modern medicine was one step closer to "the artificial man," where human organs could be produced in laboratories. But when the patients soon started dying, serious allegations of research fraud started to emerge against Macchiarini and his methods. At the same time, his operations were investigated by the police for suspected manslaughter. But Macchiarini was backed by the prestigious Karolinska Institute (home of the Nobel prize), which found that all in all he had done nothing wrong. Paolo seemed to be free of the accusations, that is until he let a team of investigative reporters into his world of the academic elite.
