Distribution pattern of the Acr-Hox2-5, Hox7 and Post2 transcription products in mid-trochophore larvae of Acanthochitona crinita. Anterior faces up. Autofluorescence (grey) and specific transcription product distribution (yellow). Left column: single sagittal section. Middle and right column: ventral and ventro-lateral whole mount clipping plane projection. Transcripts of Acr-Hox2 are present sub-epidermally. Acr-Hox3 is ventrally expressed in sub-epidermal cell layers. Acr-Hox4 transcripts are present in the epidermal and sub-epidermal cell layers. Transcripts of Acr-Hox5 are present sub-epidermally. The posterior ring of Acr-Hox7 transcription products is present in sub-epidermal cell layers. Acr-Post2 transcription products accumulate in epidermal and sub-epidermal cell layers. ao apical organ, mo mouth opening, pt prototroch, rs radula sac, st stomatodaeum, trb trochoblast(s)
