Intravenous injection of MSCs ameliorates EAE. MSCs injected at days 3 and 8 after immunization (▪) halt disease severity compared with controls (▵) (P < .05 from day 17 onward). No differences were observed between controls and mice treated at day 24 after immunization (▴) (A). Administration of MSCs at day 10 (▪) or at day 15 (▴) after immunization, after disease onset, ameliorates EAE (P < .05 from day 22 [*] for mice treated at day 10 and from day 30 [§] for mice treated at day 15 compared with controls [▵] by Mann-Whitney U test) (B). Arrows indicate days of MSC injection.
