library_construction_protocol: FFPE tissue sections (5 µm) were prepared on BOND Plus slides, followed by deparaffinization, rehydration, and antigen retrieval using Tris-EDTA and proteinase K treatment. The tissues were hybridized overnight with GeoMx WTA RNA probes (18,677 genes) and stained with morphology markers (panCK, CD45, CD31, and SYTO 13). ROIs were selected and categorized into four regions: epithelium epidermis (above dermis), epithelium dermis (sinus tracts), dermis superficial inflammation (immune cells near epidermis), and dermis deep inflammation (immune cells near epithelium dermis). Using the DSP instrument, ROIs were segmented into AOIs, and indexed oligonucleotides were UV-released and collected. Spatial transcriptome libraries were prepared using NanoString's GeoMx Human Whole Transcriptome Atlas kit and Digital Spatial Profiler instrument, followed by library construction with Seq Code primers and AMPure XP bead purification. Sequencing was performed on Illumina NovaSeq 6000 (2 × 151 bp paired-end).
