PRISM enables up to 64-plex color-barcoded RNA imaging in a single round using conventional fluorescence microscopes by grading color intensity to encode RNA codes.
- Why it matters: Spatial RNA imaging has lagged in adoption because conventional microscopes support only a few fluorescence channels and existing sequential multiplexing often needs specialized cyclic instrumentation.
- What they did: PRISM uses radius vector filtering to keep color-space codewords distinguishable, then is applied to build 3D RNA atlases and tumor-normal transition landscapes across multiple tissues.
- The result: In mouse embryonic development (E12.5–E14.5) and human hepatocellular carcinoma, PRISM supports 3D spatial mapping, and it links cancer-associated fibroblasts to immune infiltration and immune response heterogeneity within and between tumor microenvironments.
