    • A bioreactor for three-dimensional culture of liver cells is disclosed. The device is characterized by the use of textile vasculatures. A model and method for optimizing vasculature parameters is also disclosed. Liver acinar structure and physiological parameters are mimicked by sandwiching cells in the space between the two innermost woven textile hollow fibers, and creating radial flow of media from an outer compartment, through the cell mass compartment, and to an inner compartment. The theoretical optimum hydraulic permeability for the two innermost semi-permeable membranes is determined based on physiological hepatic sinusoidal blood flow and pressures. Experimental studies using a flow rate and pressure monitoring systems in conjunction with phase-contrast velocity-encoded MRI confirm theoretical results. Novel woven vascular tubes with optimum hydraulic permeability are disclosed for culturing hepatocytes in the multi-coaxial bioreactor.

    • The present invention is directed to materials and reactor systems having humidity and/or gas control. The material may have high oxygen permeability and/or low water vapor permeability. In some cases, the material may have sufficient permeance and/or permeability to allow cell culture to occur in a chip or other reactor system using the material. In certain embodiments, the material may be positioned adjacent to or abut a reaction site within a chip or reactor; in other embodiments, the material may be positioned such that it is in fluidic communication with the reaction site. The material may also be porous and/or transparent in some cases. In one set of embodiments, the material include a polymer that is branched, and/or contains bulky side groups that allow the polymer to have a more open structure. In some cases, the material may include two or more layers. Each layer may have a desired property, which may include, for example, permeability, transparency, cytophilicity, biophilicity, hydrophilicity, or a structural feature. In some embodiments, the material may be chosen so as to promote cell growth within the chip or reactor.
    • 本发明涉及具有湿气和/或气体控制的材料和反应器系统。 该材料可能具有高的透氧性和/或低水蒸气渗透性。 在一些情况下,该材料可具有足够的渗透性和/或渗透性,以允许细胞培养在使用该材料的芯片或其它反应器系统中发生。 在某些实施方案中,材料可以位于与芯片或反应器内的反应位置相邻或邻接的位置; 在其它实施方案中,材料可以被定位成使其与反应部位流体连通。 在某些情况下,材料也可以是多孔的和/或透明的。 在一组实施方案中,材料包括分支的聚合物和/或包含允许聚合物具有更开放结构的庞大的侧基。 在一些情况下,材料可以包括两层或更多层。 每个层可以具有期望的性质,其可以包括例如渗透性,透明度,细胞毒性,生物亲和力,亲水性或结构特征。 在一些实施方案中,可以选择材料以促进芯片或反应器内的细胞生长。

    • The invention features modular chambers for culturing cells in which the volume of a chamber can be adjusted without compromising the seal or sterility of the chamber. The invention is based on the principle that the volume of a chamber formed between two plates sandwiching a compressible gasket and a substantially incompressible stop can be adjusted using a gasket that forms a fluid-tight seal between the plates at a plurality of levels of compression. The invention enables the culture of cells between substantially parallel and rigid plates in which a relatively large volume can be used to seed the cells and the holdup volume reduced for perfusion without opening or otherwise disassembling the system to compromise its liquidtightness and sterility. The new closed, modular and scalable cell-culturing chamber can be thus perfused and used to culture cells (e.g., hepatocytes) with high levels of cell function in organ (e.g., liver) assist systems, for production of cells, for production of cell-derived products, such as proteins or viruses, or for systems to treat biological liquids to remove toxins, such as ammonia, add cell-synthesized products, or both.
    • 本发明提供了用于培养细胞的模块化室,其中可以调节室的体积而不损害室的密封或不可靠性。 本发明基于这样的原理,即可以使用在多个压缩水平下在板之间形成流体密封的垫圈来调节形成在夹住可压缩垫圈的两个板和基本上不可压缩的止挡件之间的腔室的体积。 本发明使得能够在基本上平行的和刚性的板之间培养细胞,其中可以使用相对较大体积的细胞来种植细胞,并且减少用于灌注的保留体积,而不打开或以其他方式分解系统以损害其液体密度和不育。 因此可以将新的封闭的,模块化和可扩展的细胞培养室灌注并用于培养器官(例如肝)辅助系统中具有高水平细胞功能的细胞(例如肝细胞),用于细胞的产生,用于生产细胞 或衍生的产品,如蛋白质或病毒,或用于处理生物液体以除去毒素(如氨),添加细胞合成产物或两者的系统。
