Stages of BMSCs observed in culture. Permeabilised serum-starved BMSCs immunofluorescently stained with F-actin (red) and α-tubulin (green) and DNA counter-stained with DAPI (blue). Scale bar = 10 μm. Representative BMSC stages observed are immotile, polarised, and actively motile. F-Actin filaments accumulate at the leading edge in polarised BMSCs. Actively motile BMSCs display an accumulation of F-Actin and α-tubulin at the cell edge orientated in the direction of movement. Isotype controls, mouse and rabbit (Thermo Fisher Scientific), demonstrate specificity of staining. BMSC bone marrow-derived stromal cell, DAPI 4′,6-diamidino-2-phenylindole. (PNG 558 kb)
