Furthermore, other cell types show strong correlations between specific genes and their functions: CD37 and TCIRG1 in B cells, COL6A3, POSTN, AEBP1, OLFML3, FN1, and MXRA8 in cancer-associated fibroblasts (CAFs), FOXM1, TACSTD2, RXRA, TPD52, and CDH1 in epithelial cells, TYROBP, IFI27, C1QB, CD14, and PFKL in myeloid cells, and CSPG4, SLPI, and ERP29 in perivascular-like (PVL) cells. The gene discussed is SLPI; the disease is cancer.
