MSCs adopt a contracted shape after 2 days of culture. Scanning electron micrographs of MSCs cultured on the NW scaffold (a), with focal adhesion points forming around the NWs (b). Representative images of approximately 20 cells. c F-actin fluorescence staining of MSCs on the NW scaffold. The cell area is of 1628 ± 145 µm2, as determined by F-actin staining (n = 50 cells). d Immunofluorescence staining of the focal adhesion protein vinculin. Arrows in a denote filopodia around the cell periphery; arrows in c and d denote the aggregation of actin and vinculin in highly localized spots, respectively.
