Coexpression of parvalbumin and secretin receptor mRNA in cells in the cerebellar cortex. A,B, In these consecutive sections, parvalbumin immunoreactivity and in situ hybridization signals were colocalized in Purkinje cells and some neurons in the molecular layer. The arrows indicate two corresponding neurons in the two sections. C, In another consecutive section, GFAP-immunopositive cell bodies were mainly confined in the granule cell layer and did not colocalize with cells labeled in the in situ hybridization. Scale bar, 20 μm. GL, Granule cell layer; ML, molecular layer;P, Purkinje cell layer.
