Fig. 7. Essential role of Src-induced Arm/TCF activity in tracheal cell
adhesion. (A-F) Time-lapse observations of
btl>GFP-moesin (A-D,F) or btl>
Cat-GFP
(E) in control (B), btl>TCF
N (C),
btl>Src42AACT (A,D), btl>Src42AACT;

N (F) embryos. (A) Metastasis-like behavior of
tracheal cells expressing Src42AACT. Cells numbered 1 and 2
detached from one branch and reattached to an adjacent branch. (B-E)
Src42AACT and TCF
N synergistically caused a strong cell
dissociation phenotype. Asterisk in E indicates the autofluorescence of yolk.
Original movies for A,B,D and F are presented as Movies 8, 9 in the
supplementary material. (G) Model of the dual function of Src42A on
E-cadherin. Scale bar in B: 50 µm for B-D,F; 25 µm for E; 10 µm for
A.
