Cancerous squamous cell‐associated genes such KRT5, CDKN2A, and SERPINB3 were mainly enriched in the Stereo‐seq tumor areas, IGKC and IGLC2 were enriched in inflammatory areas, VIM in stromal areas, ADRA2A in blood vessels, and MUC5B in glands (Figures S1D and S2, Supporting Information). The gene discussed is CDKN2A; the disease is neoplasm.
