Sequencing-based platforms capture RNA on barcoded spots (10x Genomics Visium), while imaging-based platforms read hundreds to thousands of RNA species in place at single-cell resolution (MERFISH, 10x Xenium, NanoString CosMx). In oncology it maps the tumour microenvironment, immune exclusion and clonal territories, and it underpins atlases such as the Human Tumor Atlas Network.","status":"emerging","asOf":"2026-09-04","wikipedia":"https://en.wikipedia.org/wiki/Spatial_transcriptomics","links":[{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Spatial_transcriptomics"}],"tags":[],"related":[],"cancers":[],"sections":["diagnostics","drug-discovery"],"technologies":["single-cell-spatial","digital-pathology-ai"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"notes":[],"principle":"Tissue sections are either overlaid on barcoded capture arrays whose oligonucleotides record position before sequencing, or hybridised with fluorescent probes read out over many imaging rounds with combinatorial barcodes.","strengths":["Keeps position, which single-cell sequencing discards","Reveals immune exclusion, niches and cell neighbourhoods","Works on archived formalin-fixed tissue on newer platforms"],"limitations":["Costly and data-heavy, mostly research use","Spot-based methods mix several cells per spot","No agreed clinical assay yet"]},"route":"/technologies/spatial-transcriptomics/","neighbours":{"section":[{"id":"diagnostics","kind":"section","name":"Diagnostics & Biomarkers","route":"/fronts/diagnostics/"},{"id":"drug-discovery","kind":"section","name":"Drug Discovery Platforms","route":"/fronts/drug-discovery/"}],"technology":[{"id":"digital-pathology-ai","kind":"technology","name":"Digital pathology & AI","route":"/technologies/digital-pathology-ai/"},{"id":"single-cell-spatial","kind":"technology","name":"Single-cell & spatial profiling","route":"/technologies/single-cell-spatial/"}]}}
