Fig. 4. Lactacystin inhibition of ventral furrow formation. Time-lapse microscopy
of ventrally-oriented Ubi-GFP.nls embryos. (A) Images from a
time-lapse recording of a mock-injected embryo. (B) Images from a time-lapse
recording of an embryo injected with lactacystin. (C) Images from a time-lapse
recording of an embryo injected with dsRNA to twi and sna.
Shown here is an example of a mildly defective ventral furrow. (D) Images from
a time-lapse recording of an embryo injected with dsRNA to twi and
sna. Shown here is an example of a severely defective ventral
furrow.
