CB₂ receptor immunostaining and quantification in DM-affected dogs. Representative photomicrographs for CB₂ receptor immunostaining using DAB (A) and its quantification (B) in the grey matter of the ventral horn in T7-T10 spinal cord sections of DM-affected and age-matched control dogs. Values are expressed as means±s.e.m. for 5-6 animals per group. Boxed region in DM dog image is shown enlarged in panel below. Data were analysed using the unpaired Student's t-test (*P<0.05 compared with control animals). Scale bars: 150 µm and 50 µm (enlargement). Arrows indicate CB₂ receptor-positive cells.
