    • A three-dimensional microwell system that supports long term pluripotent cell culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured pluripotent cells remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel®-coated, tissue culture-treated polystyrene dishes. Microwell-cultured pluripotent cells maintain pluripotency, differentiating to each of the three embryonic germ layers. Pluripotent cell aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain pluripotent cell growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct pluripotent cell differentiation by generating monodisperse EBs of a desired size and shape. Cardiomyocyte-rich EBs are obtained from pluripotent cells cultured in microwells of defined size and shape.
    • 描述了支持长期多能细胞培养和形成均质胚状体(EB)的三维微孔系统。 微培养的多能细胞在培养物中保持存活和未分化数周,并在传播至经Matrigel®涂覆的组织培养处理的聚苯乙烯培养皿时保持未分化的复制。 微孔培养的多能细胞保持多能性,与三个胚胎胚层分化。 可以将从微孔释放的多能细胞聚集体传代为未分化复制或分化为单分散EB。 在三维中约束多能细胞生长的能力有利地提供了更有效,可重复的未分化细胞的培养,高通量筛选,以及通过产生所需大小和形状的单分散EB来引导多能细胞分化的能力。 富含心肌细胞的EB是从在规定尺寸和形状的微孔中培养的多能细胞获得的。
