Tumor targeting ability of CD166.BBζ CAR-T cells was evaluated. Intratumoral T cells were detected by immunohistochemical assays (a, b) (shown in brown) and immunofluorescence (c, d) (shown in red), scale bar, 200 μm. The results are presented as the mean ± SD from experiments that were performed in triplicate (*P < 0.05, **P < 0.01)
