Distribution of NPWa-positive neurosecretory cells on V. multiformis. a A schematic representation of V. multiformis. Positions of the following images are indicated. b-e NPWa-positive cells were scattered on aboral (b, c) and oral (d, e) subepithelial surfaces. NPWa-positive cells on the aboral surfaces (b, c) displayed spindle-like or polygonal shapes and some of them had short processes (arrowheads in c), whereas cells on oral surfaces were spherical (d, e). f, g NPWa-positive spherical cells were enriched in the distal tissues of the body. Scale bar, 50 μm (b, d and f) or 10 μm (c, e and g)
