Fig. 1

Tibia fractures were created in 8 to 10-week-old SMA9 mice. Tamoxifen was injected on −1 and 0 DPF, and samples were collected for flow cytometry on 0 (unfractured periosteum), 4 and 10 DPF (fractured tibias). Two intact or fractured tibias were pooled for each sample, n = 3 for each group. a Representative dot plots for SMA9 cells and PDGFRβ+ cells gating in periosteal callus 4 DPF by flow cytometry. b SMA9 and c PDGFRs expression was analyzed within live, non-hematopoietic (CD45/Ter119/CD31)− cells. Values are expressed as mean ± s.e.m. *p < 0.05, **p < 0.01, ***p < 0.001. Statistical test: One-way ANOVA with Tukey’s post hoc test (b) and two-way ANOVA with Tukey’s post hoc test (c).
