Morphological and Molecular Characterization of Human Gingival Tissue Overlying Multiple Oral Exostoses
MMP-2 activity. (a) Representative SDS-zymography and (b) bar graphs showing MMP-2 activity in serum-free cell culture supernatants of fibroblasts from healthy and overgrown gingivae after densitometric analysis of immunoreactive and lytic bands. Data are expressed as densitometric units and are for samples run in duplicate. .
