Fig. 3. Engrailed expression fades in srt7E4 embryos.
(A) En expression in the non-paternally rescued
srt7E4 embryos at stage 9. The expression of En has been
lost from many of the target cells that normally express En in response to Wg
signaling in the ventral epidermis. (B) En expression in paternally
rescued srt7E4 embryos at stage 9 is indistinguishable
from wild type. Paternal rescue, embryo orientation and data collection from
three optical sections are exactly as described in
