MDK was overexpressed and positively correlated with MVD in NPC. a Representative images of immunohistochemical staining for MDK in NPC specimens and healthy control. Magnification, × 20. b Examination of MDK expression in the NPC tissues with different clinical stage. c A high expression of MDK was significantly associated with a poor OS. d Representative images of immunohistochemical staining for MVD with low or high levels of MDK in stage 1 and stage 4 NPC tissues. e A positive correlation between MDK expression and MVD in NPC tissues. **, P < 0.01
