Tumor cells emigrated in mouse blood (Figure 2C) and seeded in the lung (Figure 2D) were in turn captured and identified using the CAM uptake Vita‐AssayTM invasion assay, showing iCTCs and liver or lung micrometastases that retained the TP phenotype as GFP+CAM+; and expressed seprase as well (Figure 2E). The gene discussed is FAP; the disease is neoplasm.
