ResumoA monoclonal antibody, termed JD1, was generated that bound to a subset of the nerve cells in the hypostome and tentacles of Hydra oligactis. Using a whole-mount technique the spatial pattern of the subset of nerve cells and their processes could be clearly visualized using indirect immunofluorescence. The subset largely corresponds to the epidermal sensory cells. Using the same technique the development of the pattern during head regeneration and budding was examined. The appearance of the nerve cells coincides with the formation of both the tentacles and hypostome. When head regeneration does not occur, JD1+ cells do not appear suggesting the differentiation of JD1+ cells is an integral event in head formation dependent on antecedent patterning processes.
