BmMSCs constitutively express GAP-43 protein, and HS and P/PL significantly similarly increased the GAP-43 IF score at day 14 compared to day 0. a Immunofluorescent staining of human myoblast SJCRH30 cells (Pos control; representative of n = 2), day 0 (representative of n = 8 donors), day 14 post-HS (representative of n = 4 donors), and post-P/PL (representative of n = 8 donors) treatment. Image dimensions, 1249 μm × 1102 μm. b Percent GAP-43 positive cells. c Immunofluorescent score. *p < 0.05 vs. day 0 (ANOVA)
