  Fig. 1. Spatial expression of Xversican mRNA in early Xenopus laevis embryos. (A) Xversican maternal transcript is distributed in the animal pole blastomeres of the blastula stage embryo (st. 6). (B,C) During gastrulation (st. 10.5 and 12.5 respectively) the mRNA is localized in the gastrulating dorsal axial mesoderm (arrows). (D) Dorsal view of a midneurula stage embryo (st. 16): the expression can be detected in the paraxial mesoderm (arrow) and in the midline of neural plate (arrowhead). (D Frontal view of the embryo shown in (D) exhibiting Xversican transcript in the eye field (e). (D) Vibratome transverse section of the embryo in (D) revealing the presence of Xversican mRNA in the notochord (arrow), in the medial ventral domain of the neural plate (np) and in the paraxial mesoderm (pm). (E) Dorsal view of late neurula stage embryo (st. 18). Xversican is detectable in the premigratory trunk NCC (arrowheads) and in the lateral plate mesoderm (arrow). (F, F At stage 22, Xversican transcript is still present in the trunk NCC (arrowheads) and appears in the cardiac field (cf), pronephrus (p) and pronephric ducts (pd). (F Vibratome sagittal section reveals the labelling in the floor plate of the neural tube (arrow) and the down regulation of Xversican in the forming somites (so).
