Abstract: The present disclosure provides a method for producing a cell-culturing polyvinyl alcohol-based nanofiber structure, the method comprising: electrospinning an electrospun solution to form a nanofiber mat, wherein the electrospun solution contains polyvinyl alcohol (PVA), polyacrylic acid (PA) and glutaraldehyde (GA); crosslinking the nanofiber mat via a hydrochloric acid (HCl) vapor treatment; and treating the crosslinked nanofiber mat with dimethylformamide (DMF) solvent to crystallize the nanofiber mat.

Abstract: Disclosed is a nanofiber-based long-term primary hepatocyte culture system and a culture method, wherein the primary hepatocyte culture system has an advantage that it can culture cells in three-dimensions in vitro to maintain the original physiological activity of low proliferative primary hepatocytes for a long time by co-culturing indirectly by separating primary hepatocytes and hepatic non-parenchymal cells with a support consisting of nanofibers therebetween without direct co-culture.
