Fig. 5. Inactivating M/Z Ena does not disrupt cell adhesion. F-actin (except
I,J, DE-cad). (A-J) Extended germband. mat-FP4mito and
M/Zena23. Morphology (A-D), cortical actin (E-H) and
DE-cad (I,J) normal. (K,L) Early germband retraction.
mat-FP4mito (L) amnioserosal cells (brackets) do not overlap posterior
epidermis (arrows) to the same extent as wild type (K). Smaller cell size in
mat-FP4mito is probably because of overall smaller size of embryos, because of
defects in nurse cell dumping. (M-P) Germband retraction. (M,N)
Wild-type. Amnioserosa and epidermis maintain close contact throughout
(arrows). (O,P) mat-FP4mito. Arrows, amnioserosa detached from epidermis.
Arrowheads in P, deep segmental grooves. Scale bars: 20 µm.
