MedChemExpress mature myotubes

FAPs accounted for the disparity in NMJ regeneration between MAS and TA muscles. (a) AChR and MyHC immunolabelling in <t>myotubes</t> differentiated from MuSCs isolated from MAS or TA muscles. Mature myotubes were treated with or without agrin (100 ng/mL) for 16 h. Scale bar = 50 μm. Graphs in the right panel show the quantifications of differentiation index (upper left), myotube width (upper right), AChR cluster counts normalized to myotube area (lower left), ratio of AChR/myotube area (lower middle) and Chrna1 expression quantified by real‐time quantitative PCR (lower right). n = 3. (b) AChR and MyHC staining of MuSCs single culture and cocultures with different FAPs. Scale bar = 50 μm. Graphs in the lower panel show (from left to right) the quantification of differentiation index, myotube area, AChR cluster density and ratio of AChR/myotube area. n = 3. (c) Schematic of the direct coculture of different FAPs with MAS‐derived MuSCs. (d) Representative images of tdTomato + FAPs and α‐BTX labelled AChRs (green) in recipient MAS and TA muscle. Scale bar = 20 μm. (e) Schematic of the FAPs transplantation assay. (f) Quantification of BTX signals per field. n = 6 mice/group. The data are shown as mean ± SD. Unpaired Student's t test was used in (a, upper right panel). Two‐way ANOVA followed by Tukey's post hoc test was used in (a, lower right panel and f).
