Morphological characterization of HAEC and cell circularity. Confocal fluorescence microscopy (CFM) images of HAECs at D2 on flat silicon (a and b), MacroPSi (c and d), and NAA (e) modified with Col and Fn. Cells were stained with NucGreen for the nucleus and Phalloidin for actin filaments. The circularity of HAEC at D2 on MacroPSi and NAA substrates Col- and Fn-functionalized (f)
