Little skate (leucoraja erinacea) pharyngeal arch sequencing stages 22 and 26
This RNA-Seq data was created to identify genes unregulated in the gill arch signalling centre (the gill arch epithelial ridge, GAER) of the little skate (leucoraja erinacea). These libraries are generated from tissues extracted during two stages of development, stage 22 when Shh-signalling has an anterior-posterior patterning role on the gill arch skeleton, and stage 26 when Shh signalling drives proliferation of branchial ray progenitors. The tissues collected include the posterior (shh-expressing) half of gill arch 1 compared to the anterior half as control at stage 22, and the distal tip of the gill arch (GAER) and adjacent non-GAER (as control) gill arch tissue in stage 26 embryos.
