Figure Lengend Snippet: Biomarker expression in CTCs and LEVs of AVPC. ( A ) Example of HSPD1 expression in LEV (top panel), apoptotic (middle panel) and CTC (bottom panel). Cropped ROI images are shown with individual IF channels and IF composite image with DAPI (blue), CD45 (green) and pan-CK (red). The IMC rendered image of HSPD1 signal is shown in green. vs. CD45 for all objects within the full ROI with WBCs in purple and the cell of interest (circled) in red (full cell), green (cytoplasm) and teal (nucleus). ( B ) Selected biomarkers shown for LEVs (top 2 panels) and CTCs (bottom 2 panels), with EpCAM expression varying from negative (0) to strong (3+). Scores from the 0–3 scale is shown for each marker and object. Scale bar is 10 µm.
Article Snippet: CTCs and LEVs confirmed by 40× imaging were relocated in the Hyperion IMC instrument (Fluidigm, South San Francisco, CA, USA) using a defined offset between coordinates of the 80i microscope (Nikon, Melville, NY, USA) and the Hyperion stage.
