Model Hirano bodies detected as eosinophilic inclusions in 3 month old R26CT-CRE mice. Paraffin embedded brain sections from 3 month old R26CT and R26CT-CRE mice were dewaxed and stained with Gill's hematoxylin and counterstained with eosin. 3 month old R26CT mice show no rod-shaped eosinophilic inclusions in the pyramidal cells of the hippocampus or cerebral cortex. 3 month old R26CT-CRE mice show no inclusions in the cerebral cortex, but contain rare eosinophilic inclusions in CA1 pyramidal cells of the hippocampus indicated by the arrow. Scale bars represent 20, 50, or 500 μm.
