During the myelin recovery phase of the MS model (5 wpi), the double-labeling results showed that remyelinated MAG expression was increased in the spinal cord of CKO mice; furthermore, a thicker myelin sheath surrounding almost all axon diameters was observed in the WM of CKO mice than in EGR1fl/fl mice (Fig. S11D–F). Here, MAG is linked to myeloid sarcoma.
