Images

	Blue channel shows Calca expression; green channel shows Htr3a-EGFP expression.
	Green channel shows Htr3a-EGFP expression.
	Blue channel shows Calca expression.

Results Notes

Expression of Htr3a-EGFP transgene and Calca (CGRP) is noted in the lumbar-sacral dorsal root ganglion (EMAPA:16668). EGFP expression is present, strong, and visible in single neuronal cell bodies of the ganglion, as well as axons. Calca is present, weak, and visible in single neuronal cell bodies of the ganglion.
