Fig. 7. Large axons are hypomyelinated in the Ebf2^-/- sciatic nerve. (A) Toluidine Blue-stained transverse semi-thin section of a wild-type sciatic nerve at postnatal day 30. (B) Section of a P30 Ebf2-null sciatic nerve that corresponds to that in A. Note reduced myelin thickness of sample large caliber Ebf2^-/- axons indicated by arrowheads in B, in comparison with Ebf2^+/+ fibers of similar sizes in A. Scale bar: 10 µm.
