VEGF Induce Vasculogenic Mimicry of Choroidal Melanoma through the PI3k Signal Pathway

Figure 1

Positive VEGF expressions of VM in CM specimens (200×). (a) The expression of VEGF was significantly higher in CM than in the negative control, especially along the VM compared to the stromal cells. (b) The IOD of VEGF was significantly higher in CM than in the negative control (p=<0.001). (c) CD34-negative and PAS-positive channels were considered as VM (yellow arrows).
