the expression of specific peptidergic substances ( related to the molluscan peptide phe-met-arg-phe-nh2 , as described in the accompanying paper ( p. f. copenhaver and p. h. taghert , 1988 , dev . biol . 130 , 70-84 ) commences within the ep cell population only after these migratory phases are complete and can be correlated with the outcome of cellular migration : only neurons that navigate onto the midgut regions of the plexus subsequently exhibit the peptidergic phenotype .
