Fig. 2. Expression of Xsl-1 RNA. All embryos are pictured with the anterior to the left unless otherwise noted (B,E,K). Stages 12 (A–C) and 17 (D–E) are shown from dorsal views (A,D), frontal views (B,E), where dorsal is to the top of the frame, and as saggital sections (C,F). Stages 24 (G), 28 (H), 33 (I,L,M), and 37 (J,N) are shown as lateral views. Panel K is a transverse section of a stage 37 embryo at approximately the level of fourth trunk somite. High magnification views of a cleared stage 33 embryo are pictured in L (anterior) and M (posterior). A high magnification view of expression in the pronephros, somites, and neural tube of a cleared stage 37 embryo is seen in N. Further description of the arrows and arrowheads can be found in Section 1. |
