SRSF7 and neoplasm: Through CellChat analysis, we established the intercellular communication network between most cells, including tumor cells, fibroblasts, T-NK cells, and various subtypes of MCs, etc., as a way to characterize the relationship between the subtype of C1 SRSF7+ MCs and other cell types, and at the same time, we identified the three modes of outgoing, incoming and their corresponding signaling pathway expression.
