Next, we examined the effect of 89Zr-oxine radiolabeling on cell migration of CAR-T cells using a Boyden chamber assay to measure the response to IL-13Rα2Fc chimeric protein or conditioned medium obtained from IL-13Rα2 positive and IL-13Rα2 negative human glioma cell lines. This evidence concerns the gene IL13RA2 and central nervous system cancer.
