Figure 9. Immunolocalization of alpha smooth muscle actin in the iris and cornea of 1- to 2-month-old mice. The pupillary muscle (pm) is positively stained and easily discerned in the wild-type (WT) and matrix metalloproteinase-9 knockout (MMP-9KO) mice. The altered structure of the iris and adhesions (ad) between the anterior iris and the corneal endothelium resulted in aberrant expression of alpha smooth muscle actin (αSMA) in the transgenic (TG) and TG/MMP-9KO mice. 40X, bar=50 µm.
