Gene expression of osteogenic markers by MSCs indirectly co-cultured with M0, M1 and M2 macrophages. MSCs were indirectly co-cultured with three types of macrophages and their key osteogenic gene expression was determined by RT-PCR after 3 days (a), 7 days (b) and 14 days (c). Statistical analysis was performed by one-way ANOVA with Dunnett’s post-test. n = 4, *P ≤ 0.05, ** P ≤ 0.01, *** p ≤ 0.001
