Average clinical grades (a) and inverted screen hang times (b) of MuSK- and CFA-immunized mice with or without dental follicle mesenchymal stem cell (DFMSC) treatment. MuSK-immunized mice treated with DFMSC (MuSK-SC) showed significantly reduced clinical grades and increased screen hang time than non-treated mice. Asterisks only denote significant differences between MuSK and MuSK-SC groups as calculated by post hoc analysis. *p < 0.05; **p < 0.01 by Kruskal–Wallis and Dunn’s post hoc test or ANOVA and Tukey’s post hoc test, as required. Vertical bars indicate standard errors. Note that in Fig. 4a, the values of CFA and CFA-SC groups overlap since the average clinical grade for both groups is 0 (no disease) at all time points
