Fig 6. Patient 38 with circulating tumour clusters isolated by the ScreenCell^® Cyto kit.

ICCs were performed using anti-pan-CK/CK-7/vim and CD45. Cell nuclei are counterstained with DAPI. Circulating tumor clusters (bold arrow) showing pan-CK/CK-7⁺/vim⁺ but CD45^-. CD45⁺ leukocytes are sometimes CK⁺. Cells caught in the filter pores (red arrow). Images were captured under 400X magnification. Scale bar represents 20 μm.
