MOESM1 of SP, CGRP changes in pyridoxine induced neuropathic dogs with nerve growth factor gene therapy

Additional file 1: Figure S1. Nerve growth factor (NGF) immunostaining of the dorsal root ganglion (DRG) in the vehicle-treated (A), and NGF gene-treated (B) groups at 4 weeks after 1 week of pyridoxine injection. In the vehicle-treated group, NGF immunoreactive neurons are not detectable in the DRG. In the NGF gene-treated group, NGF immunoreactive neurons are abundantly observed in the DRG. Scale bar = 50 μm
