Fig. 6. TEM images of neuroepithelial cells (NECs) in (A) the filament of O.
mykiss and (B) the lamella of C. auratus. Lower left-hand insets
(areas indicated by broken red boxes) show the presence of dense-cored
vesicles (arrowheads). Note the proximity of NECs in both A and B to a red
blood cell (RBC), as well as a nerve (N) and the basal lamina (BL) in A. The
NEC of the goldfish lamella (B) is also juxtaposed to a pillar cell (pc) and
near the ambient environment (H2O). Scale bars, 500 nm.
