Finding bundle

Cell-context dependence: the same gene perturbation produces measurably different transcriptional and phenotypic signatures across cell contexts (iPSC-derived neurons vs. HEK293 vs. primary cells), so single-context perturbation atlases cannot be assumed to generalize without cross-context validation.
