Fig. 7: SPP1 signaling in cell-cell communication.

a The cell-cell communication between CSC and Macro_SPP1 at the single-cell level. b The role of cluster 3 in the cell-cell communication in the tumor boundary area of cluster 3. (c) The outgoing pattern of the CNV clusters in the tumor boundary area of cluster 3. d The SPP1 signaling pathway network in the tumor boundary area of cluster 3. e The ligand-receptor pairs in SPP1 signaling pathway signaled by cluster 3 to all clusters.
