Galactosylated electrospun membranes for hepatocyte sandwich culture

- Electrospun PU membranes were applied for hepatic sandwich culture.
- Galactose was immobilized on PU fibers via UV-crosslinked layer-by-layer deposition.
- Hepatocytes covered by a Gal-membrane formed multi-cellular aggregates.
- Coverage of a Gal-membrane enhanced hepatic albumin-secretion function.
