Welcome to “Trainee Pearls”, a new initiative brought to you by the EBMT Trainee Committee to deliver the most important messages (“the pearls”) of high-profile research works in hematology and bone marrow transplant to our fellow trainees all over the world. The topics will span from classical hematology to more focused bone marrow transplant research. The selected research article will be discussed directly with young authors who have been involved with the published work.
