Figure 3. Microfill perfusion and x-ray micro-CT angiography.
The tumor bearing mice in either the MORAb-004 treated or control group were perfused with sodium nitroprusside containing solution followed by MICROFIL (Carver) injections. The tumors retaining polymerized latex were fixed in formalin then imaged with a X-ray micro-CT system performed by Numira Biosciences, and analyzed using an image analysis software package (Altaview, Numira). Microfill perfusion of animals show extensive neo-vascularization within the tumor of CTRL treated animals A. while MORAb-004 treatment B. reduced the amount of new vessels within the developing tumor.
