MOLF mice spontaneously developed polyp-like nodules in colon at steady state.

<p>[<b>A</b>] Six months old MOLF and B6 mice were sacrificed and the colons were opened up longitudinally. [<b>B</b>] Multiplicity and size of polyp-like nodules were determined under a dissection microscope (n = 7 in each group). [<b>C</b>] H&E sections of colons from B6 and MOLF are shown. [<b>D</b>] IHC staining of colonic sections from B6 and MOLF mice was performed using anti-Ki67 primary antibody.
