Fig. 7. Immunohistochemistry with anti-VEGF antibody.
Based on immunochemical staining (×400) with an anti-VEGF monoclonal antibody, group 1 and group 2, both of which received an ADSC injections, displayed more noticeable brown-colored staining. In particular, anti-VEGF staining was most pronounced in group 2, in which the ADSCs injection was done immediately before composite graft elevation. (A) Control, (B) group 1, (C) group 2. VEGF, vascular endothelial growth factor; ADSC, adipose-derived stem cell.
