Structure	Level	Pattern	Image	Note
TS21: spinal cord lateral wall	Strong	Regionally restricted	1D , 1C	Expressed in the dorsal funiculus where central fibers of dorsal root ganglion neurons elongated. Some positive cell bodies were seen in the dorsal spinal cord.

Structure	Level	Pattern	Image	Note
TS23: spinal cord dorsal horn	Present	Regionally restricted	1F , 1E	Expressed mainly on the collateral fibers of dorsal root ganglion neurons, although some positive cell bodies were weakly stained.

Structure	Level	Pattern	Image	Note
TS28: dorsal root ganglion	Present		2A	Data was summarized in Fig. 3, average area of positive neurons was significantly smaller that that of negative neurons.

Structure	Level	Pattern	Image	Note
TS28: spinal cord dorsal horn	Present	Regionally restricted	2B	Expressed in the fibers, not the cell bodies. Expressed in superficial layers.
