Capture and analysis of circulating tumour cells.
Upper panel: sketch of the technology we have developed for the capture and study of tumour cells. Arrays of columns containing magnetic particles with antibodies directed against the cells of interest are self-assembled under a magnetic field in a microfluidic channel. The sample (e.g. blood from a patient) is flown in the channel. The cells bearing the relevant surface antigens (red and blue) are captured, whereas negative cells (blue) are not. The captured cells can be stained with different biomarkers, observed and studied with high accuracy after their capture. The lower panel displays a real image of cancer cells from a lymphoma patient, with multiple immunostaining (green, yellow and red antibodies, and blue DNA marker), imaged by confocal microscopy in situ after capture.
