Shared tumor cell clusters were distinguished by expression of Hedgehog signaling (C0, PTCH1), immature Schwann cell (C1, PDGFRA), extracellular matrix (C3, LUM), growth factor signaling (C4, FGFR1), non-myelinating Schwann cell (C6, NGFR), mesodermal (C7, SFRP4), cell proliferation (C9, MKI67, TOP2A), and steroid signaling genes (C11, PTGDS) (Fig. 1d and Supplementary Fig. 4b). Here, FGFR1 is linked to neoplasm.
