EphrinB2 controls grouping of MN into LMC divisions. A/ Transverse vibratome sections of E13 control (a) and EfnB2 ^cKO (b) embryos were immunostained to detect Foxp1 (red) and Islet1 (blue). B/ Schematic representation of the image analyses used for quantification (a, b). Quantification of the surface of overlap in images from control and EfnB2 ^cKO embryos (n = 4 embryos per genotype) C/ Quantification of the distance to the nearest neighbor of the same identity in LMCm and LMCl of control and EfnB2 ^cKO embryos (n = 4 embryos per genotype). Error bars indicate s.e.m.; **P < 0.01; ns = non significant (unpaired two-sample t-tests). Scale bars: 50 μm
