    • A polymer fiber is formed by hydrodynamic spinning. Fluids are forced to flow through a conduit to form a laminar flow comprising three or more layers of generally coaxial fluid flows, at respective flow rates selected to define a cross-section of a tubular middle layer of the fluid flows. The middle layer comprises a cross-linkable polymer precursor. Another layer of the fluid flows comprise a cross-linking agent. The polymer precursor, cross-linking agent and fluids are selected to prevent substantial diffusion of the polymer precursor away from the middle layer, and to allow a portion of the cross-linking agent to diffuse from the another layer into the middle layer to facilitate cross-linking of the polymer precursor in the middle layer to form a tubular polymer layer in a polymer fiber. The polymer layer thus has a cross-section generally corresponding to the cross-section of the middle layer.
    • 聚合物纤维通过流体动力纺丝形成。 流体被迫流过导管以形成包含三层或更多层大体上同轴的流体流的层流,其各自的流速被选择为限定流体流的管状中间层的横截面。 中间层包含可交联的聚合物前体。 流体流的另一层包含交联剂。 选择聚合物前体,交联剂和流体以防止聚合物前体远离中间层的实质性扩散,并且允许一部分交联剂从另一层扩散到中间层以促进交叉 在中间层中连接聚合物前体以在聚合物纤维中形成管状聚合物层。 聚合物层因此具有一般对应于中间层的横截面的横截面。

    • The present invention generally relates to modified substrates such as membranes for use in bioartificial organs, such as bioartificial kidneys, and other applications. Certain aspects are generally directed to a membrane or other substrate modified to facilitate the attachment of cells. In one set of embodiments, the substrate or membrane may be at least partially coated with an adhesive such as 3,4-dihydroxy-L-phenylalanine (DOPA), poly(dopamine), or other adhesive comprising a molecule having a catechol moiety, for example on one side of the membrane or substrate. On at least a portion of the adhesive coated portion of the substrate, a protein may be coated, such as an extracellular matrix protein (for example, a collagen), to which cells such as primary human renal proximal tubule cells may be adhered. Surprisingly, such a dual coating may be used to promote the attachment of such cells to a membrane or other substrate that otherwise may not promote cell adhesion. In certain embodiments, the coating may also facilitate or promote not only cell adhesion, but also cell proliferation and/or differentiation. Such membranes or other substrates may be useful, for example, in bioartificial organs such as bioartificial kidneys, hemodialysis cartridges, bioimplants, biosensors, bioreactors, etc. In certain embodiments, cells may be attached to a membrane or other substrate on only one side, while the other side may be kept free of attached cells.
    • 本发明一般涉及用于生物人造器官例如生物人造肾等的改性底物,例如膜。 某些方面通常涉及修饰以便于细胞附着的膜或其他底物。 在一组实施方案中,基底或膜可以至少部分地涂覆有粘合剂,例如3,4-二羟基-L-苯丙氨酸(DOPA),聚(多巴胺)或包含具有儿茶酚部分的分子的其它粘合剂, 例如在膜或基底的一侧。 在底物的粘合剂涂覆部分的至少一部分上,可以涂覆蛋白质,例如细胞外基质蛋白(例如胶原),细胞如原发性人肾近端小管细胞可以粘附到细胞上。 令人惊奇的是,这种双重涂层可以用于促进这种细胞与膜或其它底物的连接,否则可能不促进细胞粘附。 在某些实施方案中,该涂层还可促进或促进细胞粘附,但也促进细胞增殖和/或分化。 这样的膜或其它底物可用于例如生物人造器官如生物人造肾,血液透析盒,生物移植物,生物传感器,生物反应器等中。在某些实施方案中,细胞可以仅在一侧附着于膜或其它底物, 而另一侧可以保持没有附着的细胞。
