Electronic Theses and Dissertations
The sea lamprey is a basal lineage vertebrate and an invasive species in the Great Lakes. It possess a diffuse chemosensory system with microvillous solitary chemosensory cells (SCCs) located on papillae along the gill pore, oral disc and tail. The objectives of this study were to assess the abundance of SCCs across life stages, and to characterize the innervation and biochemical properties. At all three locations, SCCs were most abundant in the spawning stage compared to earlier life stages, suggesting a role during reproduction. Prominent calretinin and 5-HT labeling show homology to previously identified taste cells and to SCCs in …
