EAE Induction and Clinical Evaluation:

In addition, the mice received 200µg of pertussis toxin (List Biological Laboratories) intravenously on the day of, and 2 days after, peptide immunization. Individual animals were graded according to clinical severity as follows: grade 0, no abnormality; grade 1, limp tail; grade 2, limp tail and hind limb weakness; grade 3, partial hind limb paralysis; grade 4, complete hind limb paralysis; as previously described.

Tracer injection:

Five days before being killed, the animals (rats) were injected into the sciatic nerve (11 bilaterally, 30 unilaterally) with a 1% wt per vol solution of the transganglionic tracer CTB (List Biological Laboratories, Campbell, CA) using a 36-ga NanoFil syringe. The sciatic nerve was exposed as described above and 1 µl was injected into each the tibial and common peroneal branches bilaterally (4 µl total).

Treatment of EAE by DiD-Labeled MSCs:

MOG₃₅₅₅ peptide (MEVGWYRSPFSRVVHLYRNGK, Peptron, Korea) was used to induce chronic EAE in C57BL/6 mice [18]. Briefly, 200 µg of MOG₃₅₅₅ diluted in 200 µL PBS and emulsified with 200 µL incomplete Freunds adjuvant (Gibco, Germany) and 1mg/mL heat inactivated mycobacterium tuberculosis (Difco, USA) in PBS was injected subcutaneously. After MOG₃₅₅₅ administration, 200ng pertussis toxin (List Biological Laboratory, USA) was injected intraperitoneally on the day of immunization and two days later. …
