Figure Lengend Snippet: BMSCs-derived exosomes promoted osteogenic differentiation in hFOB1.19 cells via activation of the Wnt/β-catenin signaling pathway. ( A ) ALP staining was performed to assess osteogenic differentiation in each group; ( B ) Alizarin red S staining was performed to detect the mineralized area in each group; Relative mRNA and protein levels of RUNX2, OCN, OPN, Osterix, and ALP in each group were analyzed by ( C ) RT-qPCR and ( D ) Western blot; ( E ) Western blot was performed to detect the protein levels of Wnt1, β-catenin, GSK3β, and Cyclin D1 in each group. Data are presented as mean ± SD ( n = 3 independent biological replicates). *** p < 0.001 vs. the BMSCs-PBS group, ### p < 0.001 vs. the BMSCs-Exo group.
