Figure 3From: Enhanced cerebrovascular expression of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 via the MEK/ERK pathway during cerebral ischemia in the ratDouble immunofluorescence staining for MMP-9 or TIMP-1 and actin in smooth muscle cells of the middle cerebral artery after MCAO. (A-C) Photographs demonstrating the localization of MMP-9, actin immunostaining, and their co-localization in smooth muscle cells (yellow fluorescence in the merged picture). (D-F) TIMP-1 immunostaining, actin immunostaining, and their co-localization in the smooth muscle cells (white arrows). Scale bar, 50 μm.Back to article page
