Figure 4From: Matrix metalloproteinase 9 contributes to gut microbe homeostasis in a model of infectious colitisPost-infectious goblet cell hyperplasia occurs in MMP-9−/−mice. (A) Representative histology demonstrating goblet cells stained positive (red) for PAS in MMP-9+/+ and MMP-9−/− colonocytes. (B) Quantitative analysis shows similar numbers of goblet cells in WT and MMP-9−/− mice at 10d PI. A significant increase in goblet cells was observed in MMP-9−/− mice at 30d PI. *P<0.05 compared to WT-infected animals. N = 3–5.Back to article page
