Figure 2From: Matrix metalloproteinases and their inhibitors in canine mammary tumorsZymographic assay of gelatinase activity in malignant (M) mammary neoplasia, in benign (B) mammary neoplasia and in the control (C). Bands corresponding to latent and active forms of MMP-9 and to latent and active forms of MMP-2 were observed in carcinomas (M), while bands corresponding to latent forms of MMP-9 and MMP-2 were observed in adenomas (B). HT1080 fibrosarcoma cells (C) were used as the control for pro-MMP-9, pro-MMP-2 and active form of MMP-2.Back to article page
