Localization of aortic cells in the nodose ganglion by HRP retrograde transport in the cat.

Localization of the aortic cells in the nodose ganglion was attempted in the cat using retrograde axonal transport of horseradish peroxidase (HRP). Following dissection of the aortic nerve from the vago-aortic trunk, the cut ends of the aortic fibers were immersed in a HRP solution for 23--46 h. Labelled cells were found in the nodose ganglion and were located mainly in the medial border of the ganglion.
