Phenotype Image Detail
Caption Scanning electron micrographs of glomeruli made at different magnifications, with the wild-type (+/+) mice shown in the left three panels and Ptprotm1Wig/Ptprotm1Wig (-/-) mice shown in the right three panels. The major processes seen in homozygous mutant mice were broader, wider, and less distinct than the narrower, more well-defined major processes seen in the wild type mice. The overall structure of the mutant podocytes is more amoeba-like compared with the octopus-like structure of the wild type (x3,000, top panels). At high power the foot processes of the wild type mice can be seen to be regular and fingerlike in appearance in contrast to the broader, shorter (more toelike) foot processes found in the mutant mice. (x10,000, bottom panels).
