Tissue VEGF levels and capillary density. Tissue VEGF levels were significantly increased in neointestinal cysts containing VEGF-loaded microspheres compared to those with empty microspheres. (n=5) (*p<0.002) Immunohistochemical staining of PECAM-1 (CD31) in submucosal and muscular layers of neointestinal cysts containing (A) empty microspheres and (B) VEGF-loaded microspheres (100X magnification, representative images). Quantification of capillary density demonstrated a significantly increased capillary density in B than A. (n=5/group, *p<0.0001)
