title: Immunohistochemical studies for the neuronal elements in the vomeronasal organ of the one-humped camel.
abstract: The neuronal elements of the vomeronasal organ (VNO) of camel were investigated immunohistochemically. PGP 9.5 labeled the receptor cells in the vomeronasal sensory epithelium, but not the supporting or basal cells. OMP stained some receptor cells, but no immunoreactive signals for OMP were detected in the non-sensory epithelium. PLCβ2 labeled scattered cells in the sensory epithelium and a larger number of cells in the non-sensory epithelium. Double labeling immunohistochemistry revealed that the PLCβ2-positive cells were surrounded by substance P-positive nerve fibers. Collectively, these data suggest that the camel VNO bears, in addition to the mature vomeronasal receptor cells, trigeminally-innervated solitary chemosensory cells which are expected to play a substantial role in the control of stimulus access to the VNO.
