    摘要： Surfaces useful for cell culture comprise a support to which is bound a CAR material, and, bound to the CAR material, collagen VI or a biologically active fragment or variant thereof and, optionally, one or more other ECM proteins (or fragments or variants thereof) such as elastin, fibronectin, vitronectin, tenascin, laminin, entactin, aggrecan, decorin, collagen I, collagen III, and collagen IV. Also, optionally present on the surface is one or more polycationic polymers, such as poly-D-lysine or poly-D-ornithine. This surface is used in cell culture to promote cell attachment, survival, and/or proliferation of a number of different cell types such as (a) liver cells (e.g., HepG2 tumor cells, and a newly discovered line of rat liver epithelial stem cells) (b) osteoblasts, such as the murine cell line MC3T3 cell line and (c) primary bone marrow cells. Kits comprising the surfaces and additional reagents are also disclosed.

    摘要： A high throughput method is provided for identifying agents capable of producing a desired biological response in whole cells. The method includes the steps of providing receptacles having a culture surface; placing different mixtures of single agents into selective ones of the receptacles according to a statistical design; and immobilizing the mixtures of single agents to the culture surface. The method further includes contacting the immobilized agents with the whole cells; and acquiring data which is indicative of a desired biological response in the contacted cells. The method also includes using statistical modeling of the acquired data to determine which mixtures of single agents and/or which single agents in these mixtures are effective in producing the desired biological response in the contacted cells.

    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, laminin, 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, and/or proliferation of primary liver cells. The invention also relates to methods utilizing this surface, such as methods for attachment, survival, 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.
