From: Heterogeneous atypical cell populations are present in blood of metastatic breast cancer patients
Confocal immunofluorescent images of four representative triple-negative breast cancer patients. Images are stained with cytokeratin (CK) antibody (green), CD45 antibody (red), vimentin (white) and 4′,6-diamidino-2-phenylindole (DAPI; blue). Note that the vimentin-positive cells are negative for the hematopoietic marker CD45. DIC, Differential interference contrast images; EGFR, Epidermal growth factor receptor.
