    • An article for culturing cells (100) includes a substrate (110) on which cells can be cultured. The substrate has a base surface. An array of projections (200) extends from the base surface. The projections have a height of about 1 micrometer to about 100 micrometers, and have a gap distance along the major surface from center to center between neighboring projections of about 10 micrometers to 80 micrometers. A plurality of arrays of projections may extend from the surface with gaps in the base surface between the arrays. Hepatocytes cultures on such microprojection array substrates maintained in vivo like morphology and membrane polarity. Hepatocytes co-cultured with helper cells on such substrates tended to grow in the area of the arrays, while the helper cells tended to grow in the areas between the arrays.
    • 用于培养细胞(100)的制品包括其上可培养细胞的底物(110)。 基板具有基面。 突起(200)的阵列从基面延伸。 突起具有约1微米至约100微米的高度,并且在约10微米至80微米的相邻突起之间的中心至中心的主表面具有间隙距离。 多个突起阵列可以从阵列之间的基部表面中的间隙从表面延伸。 在这样的微喷射阵列基板上的肝细胞培养物保持体内,如形态和膜极性。 与这种底物上的辅助细胞共培养的肝细胞趋向于在阵列区域中生长,而辅助细胞趋向于在阵列之间的区域中生长。
