<p>Cross sections of representative cellulose scaffolds stained with Masson’s Trichrome (A-C). After 1 week post-implantation, the magnification of region of interest in (A), see inset, show the lack of collagen structures inside the collagen scaffold (D, G). As fibroblast cells start to invade the scaffold, collagen deposits inside the cellulose scaffold can be sparsely observed after 4 weeks (E, H). Concomitant with the observation of activated fibroblast (spindle shaped cells) inside the cellulose scaffold, collagen network is clearly visible inside the cavities after 8 weeks (F, I). Scale bars: A-C = 1mm, D-F = 100μm and G-I = 20μm. * = collagen fibers; black arrows = cellulose cell wall; white arrow = fibroblast.</p
