Interfering with Rab11 function affects DE-Cad levels and border-cell migration. (A) S9 controls the border-cell cluster. (B,C) S9 border cells labelled with slbo-lacZ. (B) Overexpression of UAS-Rab11DN reduces DE-Cad levels and impairs migration. (C) Overexpression of UAS-Rab11DN does not rescue the migration defects or the elevated DE-Cad levels of msn− border cells. (D) Quantification of the border-cell migration phenotype of S10 egg chambers overexpressing UAS-Rab11DN. Small insets in A and B are internal controls of DE-Cad staining. Arrowheads, BCs. Primed letters are magnifications of white boxes. BC, border cell; DE-Cad, Drosophila E-cadherin; msn, misshapen; S9, stage 9; slbo, slow border cells; WT, wild type.
