Detection of MMP-2 and MMP-9 gelatinase activity in cell lysate (A) and supernatant (B) of fibroblasts and SCC-25 cells by combined gelatinase zymography. 1–2: fibroblast control, 3–4: SCC-25 control, 5–6: fibroblast co-culture, 7–8: SCC-25 co-culture. Densitometry of MMP-2 and MMP-9 gelatinase zymography (C–F). C and D represent the densitometry of pro-MMP-9 (C) and active MMP-9 (D) bands in cell lysates. E and F show the densitometry of pro-MMP-2 (E) and active MMP-2 (F) form from supernatants.
