Ectopic expression of LCN2 promotes neuronal migration in the spinal cord of zebrafish embryos. The her4:egfp-injected control embryo (A) or her4:lcn2:egfp-injected embryo (B) was labeled with an anti-Hu antibody to detect neurons at 24 hpf. Arrowheads indicate neurons near the egfp-expressing cells (A) or lcn2:egfp-expressing cells (B). Dotted lines indicate midline of the spinal cord. All images are transverse sections of zebrafish spinal cord, dorsal to top.
