Cells from these RMPAhigh or RMPAlow gliomas were co-stained with APC-conjugated mAb against CD45 (for labeling infiltrating immune cells [45]) or CD105 (for labeling immature proliferating vessel endothelial cells [46]), and one of the PE-conjugated mAb for RTK. Here, PTPRC is linked to central nervous system cancer.
