Live/ Dead cytotoxicity viability assay at days 3 (a, b, c), 7 (d, e, f), and 14 (g, h, i).

<p>Staining also suggested directed growth of the cells on the 3D-printed scaffold in parallel with the struts. Staining highlights pattern of clustered growth on the scaffolds (e, f, h, i). Scale bar = 100μm.
