Immunohistochemical staining of the ileal
mucosa. A cryostat section from IBD SAMP1/Yit and age matched control
AKR/J mice was stained with monoclonal antibodies 500-A2, ER-MP-23, and
Gr-1 that recognise CD3-ε, tissue macrophages, and granulocytes,
respectively. CD3-ε positive cells, tissue macrophages, and
granulocyes were more abundant in the IBD lesion in SAMP1/Yit (B,D,F)
than in age matched control AKR/J mice (A,C,E). Original magnification,
×100.
