On behalf of the ASBMT Committee on Education we are pleased to introduce "Basic Principles and Practices of Hematopoietic Cell Transplantation and Cell Therapy – Question and Answer Approach,” a new feature highlighting a particular hematopoietic cell transplant and cell therapy quiz. Answers to each question appear with evidence-based “non-exhaustive” peer-review commentary.  Our aim is to provide you with a credible and freely available educational resource.  Questions generated and reviewed by Syed Abutalib, MD, Mark R. Litzow, MD, and William A. Wood, MD.
