We applied METAFlux in a community-based setting (Methods) on data acquired from primary lung cancer patients70, flow-sorted into immune cells (CD45+ EPCAM−), endothelial cells (CD31+ CD45− EPCAM−), tumor cells (EPCAM+ CD45− CD31−), and fibroblasts (CD10+ EPCAM− CD45− CD31−). This evidence concerns the gene PECAM1 and lung cancer.
