FHL2 expression is upregulated during Bzb-induced osteoblast differentiation of MM-MSCs. (A) Alizarin red staining was performed to show the osteoblast activity of differentiated MM-MSCs. (B) MM-MSCs were treated with indicated concentrations of Bzb for 7 days, and alkaline phosphatase index (API) was measured. (C) The protein level of FHL2 was evaluated by Western blot analysis after 24 h at indicated concentrations of Bzb. (D) FHL2 and osteoblast markers Runx2, ALP, and Col 1A1 mRNA expression was determined by quantitative RT-PCR at day 7. Results are expressed as mean ± SD (n = 3). **p < 0.01 vs. controls, ***p < 0.001 vs. controls.
