Substance P-like immunoreactive trigeminal ganglion cells supplying the cornea.
Trigeminal ganglion cells supplying the cornea were traced with intra-axonally transported horseradish peroxidase and, subsequently studied for the presence of substance P-like immunoreactivity. Approximately 0%-30% of trigeminal ganglion cells contained immunoreactive substance P. These cells were of a small size (15-50 micrometers in diameter) and were distributed throughout the ganglion. The ganglion cells supplying the cornea were of a relatively small size as well but were confined to the anteromedial part of the ganglion. Some of these cells were found to contain immunoreactive substance P.
