Note that the Santa Cruz antibody (C-19) labels neuronal nuclei in in the latter (inset), indicating non-specific staining. B, C, Axotomy induced reporter expression in sensory (DRG), sympathetic (stellate ganglion, SG), & motoneurons 4 d after injury.

A, Cryosections from injured DRG (inset) & distal sciatic nerve from the same mouse processed for ATF3 immunohistochemistry (Novus NBP1-85816). B, Punctate staining in the nerve proved to be non-specific fluorescence of leukocytes (note non-nuclear signal in the absence of primary antibody). C, In intact sciatic nerves, cells morphologically identical to Remak cells had at some point undergone recombination. D, Following injury, their numbers increased. E, This was attributable to their proliferation in the injured nerve (as opposed to ATF3 induction & subsequent recombination).
