FIG. 6. Features of the mesentery with expression of SmoM2. (A) Histological analysis shows a two-cell layer thick mesentery in control
embryos that is contiguous with the wall of the gut (arrows). (B) In SmoM2-expressing embryos at Nieuwkoop–Faber Stage 45/46, this
mesentery shows abnormal thickening in many areas (arrows). (C) The mesenchyme in Smo-injected embryos shows intense staining with
an antibody directed against smooth muscle actin. (D) Embryos expressing SmoM2 show much weaker staining. |
