DmVav induces defects in the migration of caudal visceral mesodermal cells (cmv; A–C) and in tracheal development (D–F). Embryos expressing wild type DmVav (Vavwt), DmVav (Δ1–207, VavΔCH-AC) or the constitutively active version of DmRac1 (RacV12) were stained using anti-HA (A–C) or 2A12 (D–F) antibodies, mounted, and photographed.
