Figure 5. Immunohistochemical staining against different mucins in conjunctivas. In immunohistochemical stainings (100X), both transgenic mice and control mice expressed the normal patterns of Muc1 (A and B). The expression of MUC5AC (G,H) and MUC2 (C,D) decreased in transgenic mice. The intensity of MUC4 immunostaining increased in transgenic mice (E,F).
