FHL2 is necessary for Bzb-induced β-catenin nuclear enrichment in MM-MSCs. Cells were treated with 2 nM Bzb for 24 h, and the expression of β-catenin was measured by Western blot (A, B). Immunofluorescence microscopy with antibody specific for β-catenin (red) and nuclei (DAPI, blue) were used to show the localization (C). Scale bars = 20 µm. OBI, osteogenic induction medium.
