Comparison of the activities of MMP-1, -2, and -9 in HUVECs. MMP activity measured by collagen zymography for HUVECs cultured for 24 h. (A) Collagen zymography. (B) Densitometric analysis of MMP-1, -2, and -9 activity in HUVECs. Control, HUVECs on the collagen film; 5 min, HUVECs on the denatured collagen film treated with collagenase for 5 min; 15 min, HUVECs on the denatured collagen film treated with collagenase for 15 min. N = 3.
