    Surface-modified bacterial nanofibrillar PHB scaffolds for bladder tissue repair
    (Taylor and Francis Ltd., 2016) Karahaliloǧlu, Z.; Demirbilek, M.; Şam, M.; Saǧlam, N.; Mizrak, A. K.; Denkbaş, E. B.
    The aim of the study is in vitro investigation of the feasibility of surface-modified bacterial nanofibrous poly [(R)-3-hydroxybutyrate] (PHB) graft for bladder reconstruction. In this study, the surface of electrospun bacterial PHB was modified with PEG- or EDA via radio frequency glow discharge method. After plasma modification, contact angle of EDA-modified PHB scaffolds decreased from 110 � 1.50 to 23 � 0.5 degree. Interestingly, less calcium oxalate stone deposition was observed on modified PHB scaffolds compared to that of non-modified group. Results of this study show that surface-modified scaffolds not only inhibited calcium oxalate growth but also enhanced the uroepithelial cell viability and proliferation.
