NT3P75-2 overexpression enhances the growth of BMSCs in vitro. a Representative images of green fluorescence protein (GFP) in BMSCs after infecting with lentiviruses (GFP, NT3, or NT3P75-2) at 3 days post-infection (n = 3). b The counting data of percent of GFP-positive BMSCs in different groups. c NT3 expression levels in BMSCs after infecting with lentiviruses (GFP, NT3, or NT3P75-2) were analyzed by western blot, and the statistical data was also presented (#P < 0.05, ***P < 0.001 by one-way ANOVA followed by Bonferroni’s multiple comparison test, n = 3). d NT3 concentrations of cellular supernatant in BMSCs after infecting with lentiviruses (GFP, NT3, and NT3P75-2) were assessed by ELISA (#P < 0.05, ***P < 0.001 by one-way ANOVA followed by Bonferroni’s multiple comparison test, n = 6). e The cell growth of BMSCs after infecting with lentiviruses (GFP, NT3, or NT3P75-2) was measured by CCK8 assays (#P < 0.05, ###P < 0.001, **P < 0.01, ***P < 0.001 by two-way ANOVA followed by Bonferroni’s multiple comparison test, n = 6)
