English: Individual cell tracking analysis (position and velocity) of multiple monocytes within a single field. Cell position and velocity were recorded for selected individual monocyte captured from flow onto activated HUVEC luminal surfaces. This was typically done for 25 monocytes in an individual field where monocyte position and XY coordinates were recorded at 1-min intervals. Circles with a black or red border denote a monocyte in the luminal and abluminal compartment respectively. Each colored track corresponds to an individual monocyte and a data summary table describing event, XY position and velocity, as described in S3 Fig.
