  Fig. 2. Spatial distribution of Xversican mRNA during branchial arches development. In each panel dashed lines indicate the level of the sections. (A) Lateral view of a tailbud stage embryo (st. 26) showing Xversican expression in the head region. (A Horizontal vibratome section highlighting Xversican transcript in the cranial mesenchyme (arrow). In brown, the immunolabelling for 12/101 antibody shows the head somites. (A) Horizontal vibratome section showing Xversican expression in the endoderm of the pouches. (B,BB) At stage 37 Xversican mRNA is expressed by the cranial NCC migrated into the branchial arches (B horizontal section) as confirmed by the expression of the NCC marker XSox9 in (B). (C,CC) Later in development (st. 41) Xversican transcript remains expressed in chondrogenic precursor cells as shown in the horizontal section in (C compared to the expression of XSox9 in (C). In each panel roman numbers indicate respectively the first, second and third/fourth branchial arches. nt, neural tube.
