Assessment of frozen muscle samples of MuSK- and CFA-immunized mice with or without dental follicle mesenchymal stem cell (DFMSC) treatment by immunofluorescence studies showed reduced neuromuscular junction (NMJ) IgG and C3 deposit proportions in MuSK-immunized mice with DFMSC treatment (a). Representative pictures of muscle sections stained for C3 and IgG (green fluorescence) and bungarotoxin (BTx) for colocalization of the NMJs (red fluorescence) (magnification for all, ×100). The immunofluorescence data represent one of 5 sections for each mouse (b). Asterisks only denote significant differences between MuSK and MuSK-SC groups as calculated by post hoc analysis. *p < 0.05; **p < 0.01 by ANOVA and Tukey’s post hoc test. Vertical bars indicate standard errors
