Figure 3From: ERalpha-status of disseminated tumour cells in bone marrow of primary breast cancer patientsImmunophenotyping of disseminated tumour cells from patients with primary breast cancer. The tumour cells were stained with an anti-cytokeratin-fluorescein isothiocyanate (green) and anti-oestrogen receptor (ER)α detected by a secondary Alexa Fluor 594 labelled goat anti-rabbit antibody (red). Nuclei are stained blue with 4'6-diamidino-2-phenylindole (DAPI) (×40 oil immersion objective). A-F: Breast cancer patients with ERα-positive disseminated tumour cells. G-H: Clusters of ERα-positive disseminated tumour cells. I: Cluster of ERα-positive and ERα-negative tumour cells.Back to article page
