Abstract
Microporous bacterial cellulose/potato starch BC/PS composites composed of a compact upper surface and transparent lower surface were fabricated by an in situ method by adding PS into the culture medium The special structure formation mechanism was explored Compared with original BC a locally oriented surface morphology was observed when the concentration of PS in the culture media was above 10 Many more free spaces were made after modification with pore size reaching 40 μm An obvious cell ingrowth tendency was observed on the porous surface of BC/PS composites as the starch content increased while most of musclederived cells could only proliferate on the surface of original BCs In vivo implantation showed the transparent fibrous lower side of BC/PS composites was much easier for neovascularization and no obvious sign of inflammation was observed
