    • The present invention provides a method of enhancing the efficiency of differentiation of hES cells into cardiomyocytes which method comprises incubating the cells under serem free conditions. The method typically includes providing cells that induce cardiomyocyte differentiation by cell to cell contact. Differentiation to cardiomyocytes can occur via two routes, namely by spontaneous differentiation and by induced differentiation. Without wishing to be bound by theory, the present inventors hypthesise that, in the case of induced differentiation, END-2 cells, for instance, are needed for aggregation to cause local high cell densities and in inducing differentation of nascent mesodern. This second step could be enhanced in any human embryonic stem cell line leading to the prediction that it will work in lines other than hES. In cell lines that undergo sponantaneous differentiation, it is hypothesised that local induction of embryoid bodies in edoderm occurs. Typically for induced differentiation this method will also comprise culturing the hES cell with a cell excreting at least one cardiomyocyte differentiation inducing factor or with an extracellular medium therefrom, under conditions that induce differentiation.
    • 本发明提供了一种提高hES细胞分化为心肌细胞的效率的方法,该方法包括在无细胞条件下孵育细胞。 该方法通常包括提供通过细胞与细胞接触诱导心肌细胞分化的细胞。 通过两种途径发生心肌细胞分化,即通过自发分化和诱导分化。 本发明人不希望受理论的束缚,因此,诱导分化时,例如需要使用END-2细胞进行聚集以引起局部高细胞密度并引起新生中胚层的分化。 在任何人类胚胎干细胞系中可以增强第二步,从而预测它将在除了hES之外的其它线条中起作用。 在经历自发分化的细胞系中,假设发生了edoderm中胚状体的局部诱导。 通常,为了诱导分化,该方法还将包括在诱导分化的条件下,用至少一种心肌细胞分化诱导因子或其细胞外培养基的细胞培养hES细胞。
