A surgeon who made headlines in 2011 for carrying out the world’s first stem-cell windpipe transplants at Sweden’s leading hospital is on trial accused of aggravated assault against three of his patients. Italian stem-cell scientist Dr. Paolo Macchiarini was once considered a leading figure in regenerative medicine and is credited with creating the world’s first windpipe partially made from a patient’s own stem cells. Sweden decided in December 2018 to reopen a previously discontinued investigation into three cases. (Anders Humlemo/TT News Agency via AP)
