KDM6B decreased the M1/M2 ratio and promoted BMSC osteogenic differentiation in the BMSCs–BMDMs coculture system. (a) RT-qPCR and WB analyses were performed to analyze the effect of KDM6B and its inhibitor GSK-J4 on the expression of BMAL1 in BMDMs. (b) Flow cytometry was used to detect the effects of KDM6B and its inhibitor GSK-J4 on macrophage polarization. (c) Statistical results of flow cytometry. (d) Immunofluorescence of macrophage polarization and statistical analysis (scale bar: 100 μm). (e) BMDMs or BMSCs were added to the upper or lower chambers of the Transwell plates, and the BMSCs in the lower chamber were osteogenically induced. The osteogenic differentiation of BMSCs in the lower chamber was evaluated via ALP staining or Alizarin Red S staining (scale bar: 100 μm).
