The study's authors conducted a reevaluation of their work after being unable to repeat the findings with a new data set. They report that, upon this reevaluation, the published flow cytometry conflicts with new chimeric antigen receptor (CAR) polymerase chain reaction data, thus nullifying the original hypothesis.

The Editors acknowledge and appreciate the transparency of the authors for bringing this issue to the journal’s attention.
