VEGFA and geroderma osteodysplastica: The sequential increase of VEGF and b-FGF concentrations in the normal group, the GD patient group, or inactive GO patient group, and the active GO patient group suggests that VEGF and b-FGF may play a role in GO through the recruitment of the effector leukocytes into the inflamed tissue sites, thus orchestrating the immune response at the site of inflammation.
