Fig. 6. Genetic rescue of the forebrain defects in the Hesx1- deficient
embryos. (A,B) 12.5-dpc wild-type (A) and
Hesx1Cre/Cre (B) embryos. Note the small telencephalic
vesicle and the absence of the eye in the mutant embryo (B).
(C,D) 12.5-dpc
Hesx1Cre/Cre;R26Cond-Hesx1/+ compound embryos.
Note the significant rescue of telencephalic development, but very little (D)
or no rescue (C) of the eye defects. (E,F) 12.5-dpc
Hesx1Cre/Cre;R26Cond-Hesx1/
Cond-Hesx1 compound embryos showing significant rescue of
both telencephalon and eye development.
