For the CCK8 proliferation assay, BMSCs (3000 cells per well) were seeded in 96‐well plates and incubated at 37°C with 5% CO2. The plate was subsequently processed with Cell Counting Kit 8 (CCK8) solution (10 μL; Dojindo, Japan) for specified durations (0, 12, 24, 36 and 48 h) at 37°C. Optical density was measured at 450 nm to calculate the percentage of cell viability on a microplate reader (Spectramax, USA).
