CAR T cell migration in vitro to osteosarcoma cell lines. Chemotaxis assay is performed adding starving CAR T cells in transwell chambers over osteosarcoma cell lines preincubated (red) or not (blue) with anti-B7-H3-FITC mAb. Basal and positive control (FBS) are included. After 4 h, CAR T cells migrated are collected and counted by flow cytometry. Migration index mean ± SD of independent experiments from three different donor is shown
