Expression of netrin-1 and its receptor Unc5c in the mouse embryo. A, At E10.5, netrin-1 is expressed in the floor plate (FP) and dermamyotome (DM). B, A higher-magnification view of the floor plate in A. C, At E11.5, netrin-1 expression in the floor plate continued. D, A higher-magnification view in C. E, At E10.5, the netrin receptor Unc5c is expressed in the DRG neurons (dashed circle), dermamyotome, epidermis (EP), and ventral horn (VH). F, A higher-magnification view of the DRG region in E. G, At E11.5, Unc5c expression continued in DRG neurons (dashed circle). H, A higher-magnification view of G. SC, Spinal cord; LFP, lateral floor plate; MFP, medial floor plate. Scale bars: A–E,G,H, 100 μm; F, 50 μm.
