Identification of BMSCs, BMSC‐exos and osteoblasts. A, observation of BMSC morphology; B, BMSC morphology after adipogenic induction; C, BMSC morphology after osteogenic induction; D, BMSC surface antigens were detected by flow cytometry; E, BMSC‐exos were identified by a TEM; F, exosome diameter was measured by NTA; G, expression of CD36 and Alix was detected by Western blot analysis; H, expression of exosomal miR‐206 was assessed using RT‐qPCR; I, observation of osteoblast morphology; J, osteoblasts were identified by ALP staining; N = 3; *, P < .05 vs the NC group; the measurement data were expressed as mean ±standard deviation, one‐way ANOVA was used for comparisons among multiple groups, and Tukey's post hoc test was used for pairwise comparisons after one‐way ANOVA
