Commercial cell-based skin regenerative products are highly expensive, carry the risk of rejection and require a long cell culture period to manufacture. This work describes the synthesis of bilayer films from poly(globalide) (PGl) and regenerated cellulose nanofibers (rCNFs) and their use as a cell-free scaffold to support keratinocyte attachment and proliferation. The method is simple, eco-friendly (as the cellulose precursor is obtained from agricultural waste) and of low cost. The rCNFs were produced by acid hydrolysis and PGl was obtained via enzymatic ring-opening polymerization. The bilayer films were synthesized by layer-by-layer casting at ambient temperature. All the films showed a well-defined interface between PGl and cellulose. The produced rCNF/PGl bilayer films showed cell metabolic activity far superior in comparison with pristine PGl regarding the keratinocyte growth, which illustrates the potential use of these materials in skin tissue engineering.
