rps genes are dynamically expressed in development. a Expression of all five rps genes examined was observed in the stage 10 gastrula, stage 16 neural folds, and migrating CNC at stage 20–22. b Each gene was widely detected in the developing head at later stages (28–40), including all the pharyngeal arches, brain, eyes and ears. rps17, 19 and 29 were also robustly detected in the ventral mesoderm, while rps7 was particularly defined in somites. With the exception of rps7, transcripts of all mRNAs were detected in the dorso-lateral plate mesodermal region where the pronephros and hypaxial muscle will form. c Red lines labeled a*, b* and c* in diagrams of stage 10 and 28 embryos represent the planes of section shown in a and b
