Functional interaction between Lurap1 and Xdd1 in CE movements. (A) Xdd1 enhances dorsal convergence defect in MZlurap1 embryos. (B) Statistical analysis of the convergence defect. The extent of convergence is reflected by the angle formed between the line connecting the centre of the embryo to the labelled cells, and the line perpendicular to the dorsal (d) and ventral (v) axis in animal pole view. Bars represent the mean values ± s.d. from three independent experiments using at least 30 embryos in each condition (*, P<0.05; **, P<0.01; Student’s t-test). (C) Xdd1 enhances extension movement defect in MZlurap1 embryos. (D) Statistical analysis of the extension defect. The extent of extension is represented by the angle between the most anteriorly and the most posteriorly labelled cells, with vertex at geometric centre of the embryo. Bars represent the mean values ± s.d. from three independent experiments using at least 30 embryos in each condition (*, P<0.05; **, P<0.01; Student’s t-test). Scale bar: (A,C) 200 μm.
