Disgraced surgeon is still publishing on stem cell therapies

Paolo Macchiarini, an Italian surgeon, has been fired from two institutions and faces the retraction of many of his papers after findings of scientific misconduct and ethical lapses in his research—yet this hasn't prevented him from publishing again in a peer-reviewed journal. Despite his circumstances, Macchiarini appears as senior author on a paper published last month investigating the viability of artificial esophagi "seeded" with stem cells, work that appears strikingly similar to the plastic trachea transplants that ultimately left most of his patients dead. The journal's editor says he was unaware of Macchiarini's history before publishing the study.

"I'm really surprised," says cardiothoracic surgeon Karl-Henrik Grinnemo, one of the whistle-blowers who exposed Macchiarini's misconduct at the Karolinska Institute (KI) in Stockholm. "I can't understand how a serious editorial board can accept manuscripts from this guy."

Macchiarini was once heralded as a pioneer of regenerative medicine because of his experimental transplants of artificial tracheas that supposedly developed into functional organs when seeded with a patient's stem cells. But his career came crashing down after the Swedish documentary Experimenten showed the poor outcomes of his patients, all but one of whom have now died. (The lone survivor was able to have his implant removed.) Macchiarini was subsequently fired from KI, both the university and a national ethics board found him guilty of scientific misconduct in several papers, and Swedish authorities are now considering whether to reopen a criminal case against him.
