    摘要: The present invention provides methods of producing a surface with enhanced cell-adhesive properties comprising applying a stress to a polymeric matrix. The strained matrix is then modified by grafting a self-assembled monolayer onto the strained matrix, with the self-assembled monolayer comprising at least one exposed functional group. At least one cell-adhesive molecule can then be coupled to the at least one exposed functional group on the self-assembled monolayer to produce a surface with enhanced cell-adhesive properties.

    摘要: The current invention relates to methods of producing a surface with enhanced cell-adhesive properties comprising treating a pre-formed surface such that at least one intermediate reactive group is exposed on the surface. The exposed intermediate reactive group is then reacted to create a self-assembled monolayer, comprising at least one reactive group. The self-assembled monolayer is created non-mechanically. The reactive group is then coupled to at least one cell-adhesive molecule. The current invention also relates to cell culture devices comprising at least one oxygen-sensing compound and a cell-adhesive molecule.

    摘要: Surfaces useful for cell culture comprise a support to which is bound a CAR material, and, bound to the CAR material, an ECM protein, or a biologically active fragment or variant thereof such as elastin, fibronectin, vitronectin, lamninin, collagen I, collagen III, collagen IV, and collagen VI. Also, optionally present on the surface is an active factor, preferably a polycationic polymer or a biologically active fragment or variant thereof, such as polyethyleneimine (PEI), poly-D-lysine (PDL), poly-L-lysine (PLL), poly-D-ornithine (PDO) or poly-L-ornithine (PLO). This surface is used in cell culture to promote cell attachment, survival, maintenance of function, and/or proliferation of primary liver cells. The invention also relates to methods utilizing this surface, such as methods for attachment, survival, maintenance of function, and/or proliferation of cells. Further disclosed is the use of the surface in cell culture with serum-free medium. Methods of screening using the surface of the invention are also disclosed.
