Fig. 3From: Diagnostic performance of an immunoassay based on urine exfoliated cell enrichment nanotechnology for upper tract urothelial carcinoma: a retrospective, monocentric studyExample of the positive UTC assay result from a voided urine sample of UTUC. a UC cells (cyan arrows) and WBC (yellow arrow) were detected by immunofluorescence staining of cells captured on NS. Scale bar: 50 μm. b Magnified view of UC cells indicated by cyan arrows in (a), showing CK20+DAPI+CD45−CD11b−. c Magnified view of the WBC cell indicated by yellow arrow in (a), showing CK20−DAPI+CD45+CD11b−.Back to article page
