Patient-derived explants as tumor models

Abstract

Tumors contain heterogeneous neoplastic cells and diverse stromal elements that collectively function as dynamic ecosystems, and this complicates predictive modeling ex vivo. LeBlanc et al. utilize single-cell analysis to demonstrate that patient-derived explants replicate tumor cell diversity and transient stromal cell types in patient surgical specimens. This suggests that patient-derived explants can be valuable as tumor models.
