Surface characterization of the collagen scaffolds and analysis of cell viability. (a) Representative FESEM pictures showing the surface structure of the different hydrogenated scaffolds (without cells). (b) Live/dead staining of primary human fibroblasts cultivated for 3, 7, and 14 days on the collagen scaffolds (green = vital cells; red = dead cells).
