Interestingly, tissue inhibitor of matrix metalloproteinase 1 (TIMP-1) was also upregulated at every time point (P < 0.0005 by two-way ANOVA (n = 5)) and to a much greater degree than either MMP-2 or MMP-9 (Figure 7F).

(B) Quantification using fluorescence thresholding confirms the immunohistochemical results and shows that DyW mice have elevated fibronectin expression at each time point (P < 0.01 by t-test (n = 3)). Though this expression decreased with age, fibronectin remained persistently upregulated throughout postnatal development. Bar = 50 m.Mehuron et al.
