This dataset contains tracking results of different combinations of Hyaluronidase-treated AsPC1 and MiaPaca cells perfused on Hyaluronidase-treated endothelial monolayer under physiological flow speeds. Videos were recorded using a Nikon Eclipse Ti2-E microscope and 20x objective. Perfused cells from the generated videos were segmented using custom-trained Stardist models. Tracking was performed using TrackMate, and tracking results were analyzed using a custom CellTracksColab notebook. The dataset here contains the CSV files generated by TrackMate (Track and Spots information), the tracking data stored in the CellTracksColab format (Analysis.zip), and the analysis output used in the paper (Analysis.zip). Spesifications Sample information AsPC1 and MiaPaca cells perfused on HUVEC cells under physiological flow speeds: 400 µm/s (p1), 200 µm/s (p2), 100 µm/s (p3) and 400 µm/s (p4).
