Cytos Multimodal Pooled Screening (CytosMPS) measures CRISPR guide identity, morphology, native 3' transcriptome, and protein abundance and localization in the same fixed cells. Following IL-1{beta} stimulation, cells with higher nuclear NF-{kappa}B show lower phospho-p38/HSP27 and higher NFKBIA/DUSP1 in the same cell, a measurement neither imaging nor transcriptomics alone provides. TGFBR2 and CTNNB1 perturbations produce distinct multimodal phenotypes. Guide representation and perturbation transcriptional responses agree with an orthogonal single-cell transcriptomic platform.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
