Development of the protoscolex nervous system. A. 5-HT-IR and FMRFa-IR in the early stages of protoscolex development. Abbreviations are as in Figure 6 and sp, sucker primordium. The asterisk marks a 5-HT-IR cell in an unusual position, perhaps in the developing mtc. Note also some supernumerary 5-HT-IR cells with low signal levels next to the lateral ganglia. B. AcTub-IR in late protoscolex development. S1, S2, S3, S4 are stages 1 to 4, respectively. Bars represent 20 μm.
