在这里，我们提出了一种用于人类多能干细胞（hPSC）的稳健、快速且可扩展的心肌细胞分化方案。使用这种大规模方法衍生的心肌细胞可以提供足够的细胞数量，使其在人类心血管疾病建模、高通量药物筛选和潜在的临床应用中有效使用。

本实验的总体目标是将人类多能干细胞分化为具有高效率和可重复性的心肌细胞。该方案可以在生物反应器中放大，也可以修改以区分对单细胞培养敏感的细胞系。这种方法可以帮助回答使用人类诱导多能干细胞进行心脏病建模中的关键问题。

该技术的主要优点是成本效益高，并且对人胚胎和诱导多能干细胞都具有很高的效率、可重复性和适用性。我们今天的演示者是 Hananeh Fonoudi，她目前是 Victor Chang 心脏研究所的博士生，他从 Royan 研究所来到我们这里。包被前，使用清洁刷和蒸馏水彻底清除带有玻璃摆锤的 100 毫升旋转瓶中的任何灰尘或培养残留物。
