Tg(Fp:Gal4FF), and Tg(UAS:Myc-vangl2) transgenes induce mosaic expression of Myc-Vangl2 in the floor plate.
(A-C′) Dorsal views of the hindbrain in Tg(Fp:Gal4FF); Tg(UAS:GFP); Tg(UAS:Myc-vangl2); Tg(isl1:GFP) embryos stained with anti-MYC antibody to label Myc-Vangl2-expressing cells (A-C, red) and anti-GFP antibody to label UAS:GFP-expressing cells and isl1:GFP-expressing branchiomotor neurons (A′-C′, green). The UAS:GFP transgene is expressed at all ages in floor plate cells (A′-C′, arrows). Gal4FF induces mosaic expression of the UAS:Myc-Vangl2 transgene in the floor plate (A-C, arrows). The isl1:GFP transgene is expressed in FBM neurons (A′-C′, white arrowheads), and in the trigeminal and vagal motor neurons (B′,C′, black arrowheads). Asterisks (A′-C′) indicate Gal4FF-driven expression of the UAS:GFP transgene in the otic vesicle, trunk muscles, and skin. The Gal4FF driver does not induce UAS:GFP expression in branchiomotor neurons.
