After 72 h, flow cytometry data showed the ability to inhibit the cell proliferation of glioma cell lines transfected by pCL19A (Fig. 3C, E), as revealed by CFSE staining.72 h after the transfection of cells with pCL19A, the overexpression of the CLEC19A gene caused most of the cells to stop at 0–4 generation, and the cells transfected with mock were placed at 5–7 generation, indicating the arrest of cell proliferation in cells that were transfected with pCL19A (Fig. 3D, F) in U87 and C6 cell lines. Here, CLEC19A is linked to central nervous system cancer.
