Results: Through the constructed spatial gene regulatory network, we found that in the communication with malignant cells, the highly expressed ligands LIF and LGALS3BP and receptors IL6ST and ITGB1 in fibroblasts can promote tumor proliferation, and the highly expressed ligands S100A8/S100A9 in plasma cells play an important role in regulating inflammatory responses. Here, S100A9 is linked to neoplasm.
