Representative images of H and E-stained kidney sections from mice treated with a drug cocktail or control. (A) The control mouse kidney shows moderate to severe aging lesions (scored as a grade 3). Specific lesions include moderate nephropathy characterized by multifocal tubular basophilia (yellow arrows), glomerular atrophy and dilated Bowman’s space (green arrows) and interstitial inflammatory infiltrates (blue arrows). (B) The cocktail treated mouse kidney shows fewer and less severe aging changes (scored as a grade 1), characterized by focal tubular basophilia (yellow arrows). Magnification ×200.
