MMP-2 plays a key role in basement membrane degradation and in the migration of proliferating smooth muscle cells after vascular injury. Because low flow and shear stress have been related to the localization and progression of intimal hyperplasia, we hypothesized that flow conditions modulate in vivo MMP-2 transcription and activity in a model of injury-induced intimal thickening.
