Fig. 2. Whole-mount in situ hybridization using XMLP antisense RNA. Maternally expressed XMLP was present in cleave stages (A,B). Afterwards signals were found in the ectoderm and mesoderm of gastrula stages in (C,D). A sagittal section of stage11.5 is shown in (D). However, at neurula stage, signals were no longer evenly distributed and were restricted to neural ectoderm only (E,F,G). Subsequently, XMLP transcripts could be found in the neural folds at early tailbud stage and presumptive brain area only (H,I,M). The sagital section of (I) is shown in (J) and (K), while (L) shows a transversal section of (I). In later stages XMLP was expressed in ectoderm derivatives and pronephros during stage 27 to 34, (N,O,Q). (P) shows a transversal section of stage 34 (ac, archenteron; bt, blastocoel; bv, brain ventricle; ed, ectoderm; en, endoderm; hm, head mesenchyme; mc, mesencephalon; md, mesoderm; nc, notochord; ne, neural ectoderm; nt, neural tube; pn, pronephros; rc, rhombencephalon; sc, spinal chord).
