The P values were calculated using 1-way ANOVA with Tukey’s multiple-comparison test. A P value < 0.05 was considered significant. Data are shown as the mean ± SEM, and symbols represent individual fibers ( D ) or individual mice ( E ).

    Figure Lengend Snippet: ( A – C ) H&E and immunofluorescence staining of muscle sections from WT ( A ; n = 4), Tlr4 –/– ( B ; n = 5), and Ticam1 –/– mice ( C ; n = 5) at 4 dpi. Immunofluorescence staining showing eMyHC-labeled (red) regenerating muscle fibers and Hoechst-stained (blue) nuclei. The boxed areas are shown at higher magnification (×4) in the panels to the right. H&E staining and the corresponding immunofluorescence images represent the same field. Scale bars: 100 μm.

    Article Snippet: For the evaluation of muscle regeneration, sections were stained with anti-mouse embryonic myosin heavy chain (eMyHC) (catalog 22287-1-AP; Proteintech) and corresponding Alexa Fluor 594 secondary antibody (catalog A-11012; Thermo Fisher Scientific) to visualize regenerating fibers.
