Fig. 2. Regulation of El and Noc at early stages. (A)
dppGal4-driven expression of the Wg-pathway inhibitor
GSK3/Shaggy (Sgg) in an early third instar wing disc. Anti-El staining
(purple) is reduced in the dpp expression domain (GFP, green). (B)
dppGal4-driven expression of Wg in a late second instar
wing disc. El staining is ectopically induced in body wall regions in a
non-autonomous manner close to the dpp expression domain. (C)
dppGal4-driven expression of the Wg-pathway inhibitor
GSK3/Shaggy in an early third instar leg disc. El is reduced in the
dpp expression domain (arrow). (D) dppGal4-driven
expression of the Dpp-pathway inhibitor Brinker (Brk) in an early third instar
leg disc. El is reduced in the dpp expression domain (arrow).
