Immunofluorescence staining of actin cytoskeleton and nuclei. hASCs were treated with 2 μM FAK, 15 μM ROCK, or 30 μM ERK inhibitors, and the cytoskeleton was stained with phalloidin (red) and nuclei with DAPI (blue) at day 7. Scale bar 100 μm. BM: basic medium; OM: osteogenic medium; AM: adipogenic medium.
