Extended Data Fig. 6. NALCN loss-of-function circulating non-tumour cells (ntCZCs) resemble human and mouse CTCs and embed in distant organs.

Extended Data Fig. 6

(a) Heatmap reporting geneset enrichment analysis in the UMAP clusters identified in main Fig. 7b. Test Genesets were derived from 2,086 different tissue and cell types including bulk RNAseq of mouse normal tissues and tumours, huCTC signatures, and mouse and human intestinal stem and mature cell signatures (see Methods). (b) ZSG immunohistochemistry of aged Pdx1RNalcn+/+ (top left) and Pdx1RNalcnFlx/Flx (bottom left) mouse lung bronchioles (scale=100um). Right, the number of ZSG+ cells/bronchiole in the lungs of Pdx1RNalcn+/+ (n = 2 mice, 6 lung lobes, 121 bronchiole) and Pdx1RNalcnFlx/Flx (n = 1 mouse, 4 lung lobes, 57 bronchioles). (bar=median; **p = 0.0051 two-tailed Mann-Whitney U Test). (c) Two-photon direct ZSG+ cell clusters detected in entire lung section of a Pdx1RNalcnFlx/Flx mouse. (d) Exemplar co-immunofluorescence of tail vein injected P1RNalcnFlx/Flx ntCZCs (arrows) incorporated into the organs of recipient mice (arrows indicated ZSG+ cells, scale bar=50um).
