MMP9, MUC4, and EGFR co-localization in glioblastoma tissues. (A) MMP9 and MUC4 concomitant vascular expression in representative glioblastoma case. Co-localization of both proteins is observed in the vascular areas with double immunofluorescence. (B) EGFR and MUC4 concomitant expression in vascular areas in representative case of glioblastoma observed by immunohistochemistry and immunofluorescence. Co-localization of both proteins is observed with double IF. RBC red blood cells, white arrows indicate co-localization. Magnification, 20–40 ×.
