In this issue of Blood Cancer Discovery, Yang and colleagues present a comprehensive repository of patient-derived xenograft models of aggressive large B-cell lymphoma. The publicly available resource links disease specimens from individuals treated with diverse modern therapies (including chimeric antigen receptor T cells) to their high-risk clinical treatment histories and the molecular and transcriptional characteristics of their tumors, enabling the study of tumor cell-intrinsic mechanisms of therapeutic resistance and susceptibility to novel therapies.
