Objectives Properties of cell culture supports obtained from ultrathin multilayer films containing anionic natural polysaccharides ( PS acs) and a synthetic polycation were studied. Materials and methods Supports were prepared via a layer‐by‐layer (LbL) self‐assembly deposition method. Polymers used were: heparin (Hep), chondroitin sulphate ( CS ), hyaluronic acid ( HA ), and ι‐carrageenan (Car) as polyanions, and diazoresin ( DR ) as a polycation. PS ac layers were crosslinked with DR layers by irradiation with UV light absorbed by DR resin. Results DR/PSac films are very efficient cell culture growth supports as found from experiments with human mesenchymal stem cells ( hMSC s). Irradiation of the films resulted in changing zeta potential of outermost layers of both DR and PSac to more negative values, and in increased film hydrophobicity, as found from the contact angle measurements. Photocrosslinking of the supports led to their increased stability. Conclusions The supports allow for obtaining intact cell monolayers faster than when typical polystyrene tissue culture plates are used. Moreover, these monolayers spontaneously detach permitting formation of new cell layers on these surfaces relatively early during culture, compared to cells cultured on commonly used tissue culture plastic.
