From: Subdivision of arthropod cap-n-collar expression domains is restricted to Mandibulata
Chelicerate cap-n-collar orthologs are expressed throughout the germ band. (A) Stage 11 embryo of the harvestman Phalangium opilio in lateral view. Po-cnc (488-bp anti-sense probe) is expressed throughout the germ band, including in all prosomal appendages. (B) Same embryo as in (A) in ventral view. (C) Stage 15 embryo of P. opilio in ventral view. Po-cnc continues to be expressed throughout the germ band. Expression is additionally detected in the coxapophyses (arrowheads). (D) Expression of Cs-cnc in the scorpion embryo. Cs-cnc is detected throughout the germ band, including in the eye fields, all prosomal and opisthosomal appendages, and in the metasoma (tail). (A’-D’) Counterstaining of embryos shown in (A-D) with Hoechst. bl, book lung; ch, chelicera; ef, eye field; lb, labrum; L1-L4, leg 1-leg 4; mt, metasoma; p, posterior end; pe, pectine; pp, pedipalp. Scale bars are 200 μm for (A-C) and 500 μm for (D).
