Movie 1.

αTcat is expressed at myelin incisures in sciatic nerve. Low- and high-magnification Z-stacks (0.25μm steps; 10μm depth) of sciatic nerve sections from Ctnna3^WT and Ctnna3^{KO (GFP/GFP)} were reconstructed in 3D using Imaris. Immunofluorescence staining of myelin incisures by αTcat (magenta) and F-actin (cyan). DNA labeling by Hoechst (gray).
