Figure 7

Immunofluorescence of cells cultured on cPU membrane for 2 d (a) and 14 d (b). Anti-vimentin was used as the primary antibody and appears in the cytoplasm as green fluorescence. The nucleus is blue from DAPI staining. The seeding density was 4 × 10⁴ cells/mL. Image (3) is an overlay of images (1) and (2). Scale bar 50 μm.
