Fig. 4From: CTCs detection from intraoperative salvaged blood in RCC–IVC thrombus patients by negative enrichment and iFISH identification: a preliminary studyDetection and identification of RCC tumor cells by NE-iFISH. CTCs (blue arrow) were examined and identified as hyperdiploid CEP8+/DAPI+/CD45−, hyperdiploid CEP7+/DAPI+/CD45− and hyperdiploid CEP7+, CEP8+/DAPI+/CD45− by two independent pathologists. Cells with CD45+ were differentiated as WBC (red arrow). CEP, centromere polyploidyBack to article page
