Immunogold electron microscopy also shows dendritic and postsynaptic Smo and Ptch1 in glomeruli of the adult cerebellar granular layer. a–c Smo labeling (arrowheads) is seen in the dendritic claws (d) of granule cells that surround the mossy fiber terminal (mf). Some Smo labeling is associated with spinules (asterisks). d, e Similarly, Ptch1 labeling is also seen in the dendritic claws and spinules. Arrows indicate attachment plaques. Scale bars, 100 nm
