The clusters that were identified are as follows: (1) tumour cells that express TBXT and S100A1 at high levels7; (2) proliferating tumour cells highly expressing TBXT, S100A1 and MKI67; (3) TILs highly expressing IL7R, CD3D, CD3E and CD3G; (4) myeloid cells characterised by high CD14, HLA‐DRA and CD68 expression; (5) fibroblast cells specifically expressing the markers decorin (DCN), LUM and COL1A2; (6) B cells specifically expressing JCHAIN, MS4A1, CD79A and CD19; and (7) neutrophils specifically expressing S100A8 and S100A9. Here, S100A9 is linked to neoplasm.
