Researchers introduced a spatially resolved CRISPR screening method that profiles coding and non-coding RNA perturbation effects directly within native tissue contexts. The approach couples spatial CRISPR perturbations with total RNA readouts, enabling mapping of genetic changes to transcriptomic consequences in situ. The work, published in Nature Biotechnology, describes how the method works across tumor microenvironments and immune-competent models, linking large-scale guide RNA perturbations to transcriptional changes and clonal dynamics. A key value proposition is connecting functional genetics to localized RNA regulation without relying exclusively on dissociated cell assays. Together with the technical description, the study emphasizes scalable guide libraries and the ability to track changes in both coding and non-coding RNA. The result strengthens the toolkit for hypothesis testing in complex tissues where cell state and location both matter.
