Phenotype Image Detail
Image
Caption A and B: Kidney sections from 4 week old mice, stained with hematoxylin and eosin. Wild-type kidney (A) and Actn4tm1Mrpk/Actn4tm1Mrpk (Actn4-deficient) kidney (B) photographed at x10 magnification. C and D: At higher magnification (x40), glomerular abnormalities are clearly visible in the mutant mouse (D), but not in the wild-type littermate (C). The mutant kidney shows focal and segmental glomerulosclerosis (FSGS), with protein in tubules and areas of glomerular capillary collapse. A diseased glomerulus is indicated by an arrow (labeled "G"). A tubule filled with proteinaceous material is also indicated by an arrow (labeled "T"). E and F: Kidney sections from 10 week old mice, stained with H & E. E: Wild-type kidney. F: mutant kidney. The mutant kidney shows extensive disease, with sclerosed glomeruli, dilated tubules with proteinaceous material, and disrupted architecture. G: Gross appearance of wild-type (left) and mutant (right) kidneys from 10 week old mice.
