Fig. 2. Knockdown of Xc-Myc provokes edema and compromises organogenesis.
(A) Embryos injected with Xc-Myc morpholino (Xc-Myc
Mo) at the one-cell stage developed edema in the head and heart region
(white arrows). By stage 45 (right panels) massive edema and
associated defects in organogenesis were obvious in Xc-Myc knockdown tadpoles
(Xc-Myc Mo). (B-D) Histological analysis (stage 37) of Xc-Myc
knockdown embryos revealed profound developmental defects: somites (S), spinal
cord (SC), notochord (N), abdominal cavity (ac), heart (H), pronephros (PN),
dorsal aorta (DA) and cardinal vein (CV). (C) The heart is shown. (D) The
region containing the dorsal aorta and cardinal vein.
