Figure 3.

Defective periaxonal spacing in Mag / Cgt / mutants. Myelinated axons of (a) wild-type; (b) Mag−/−; (c) Cgt−/−; and (d) Mag−/−Cgt−/−spinal cords were surveyed for a uniform periaxonal space. Normally formed periaxonal spaces are seen in all genotypes, except for the MAG/CGT mutant. Normal intercellular spacing is highlighted by arrowheads in a and in b, where the MAG mutant lacks a periaxonal cytoplasmic collar. Bar, 200 nm.
