Bovine aortic smooth muscle cells (BAOSMCs) cultured in fibrous gelatin. a Immunofluorescent staining of cell nuclei (DAPI, white) and cytoskeletal actin filaments (F-actin, red) showing cell confluence on the surface of a free-floating fibrous gelatin scaffold. Gelatin fibers show as light gray in the DAPI channel; scale bar in the top panel is 200 μm, bottom three panels are 50 μm. b BAOSMCs on and below the scaffold surface, showing cells infiltrating the scaffold volume. Scale bar is 50 μm
