library_construction_protocol: Human DRG was harvested and flash-frozen postmortem. Samples were embedded in OCT and sectioned at 16µm onto a 10x Visium expression slide (Serial numbers V11N01-301-A1 and V11N01-301-B1) and visualized with H&E. RNA within the tissue was hybridized to barcoded probes according to manufacturer's protocol. Libraries were prepared with the Visium Spatial Gene Expression FF kit V1 from 10X Genomics and sequenced on an SP 28x150nt lane in a NovaSeq 6000.
