Oligosyndactyly mice (ROP Os/+) are a radiation-induced mutant strain with reduced glomerular number and increased glomerular size. We found that they develop glomerulosclerosis. At 3 mo, ROP Os/+ mice had diffuse mesangial expansion by light microscopy, whereas their +/+ littermates did not. Electron microscopic morphometry revealed a twofold increase in mesangial areas but no changes in the thickness of glomerular basal laminae. Mean glomerular volume was increased 1.8-fold. Cell number and thymidine labeling index were increased 1.3- and 2.4-fold, respectively. The amount of glomerular type IV collagen and tenascin but not laminin was increased by immunofluorescence microscopy. mRNA levels in microdissected glomeruli were measured by competetive reverse transcription-polymerase chain reaction and corrected for cell number. alpha 1-Chain type IV collagen and tenascin mRNAs were increased 3.2-fold and 1.8-fold, whereas laminin B1 mRNA levels were not. The levels of 72-kDa collagenase mRNA were increased 1.6-fold. Transforming growth factor-beta 1 mRNA levels were elevated 1.8-fold, but platelet-derived growth factor-B mRNA levels remained normal. This is the first analysis of glomerular molecular and cellular changes in a model of congenital nephron reduction.
