摘要

摘要

En 中文
细胞的三维(3D)形态源自复杂的细胞及环境相互作用,可作为细胞状态和功能的指示器。本研究采用深度学习来发现形态表征并理解细胞状态。本研究引入了MorphoMIL,一种结合了几何深度学习和基于注意力的多实例学习(multiple-instance learning)的计算流程,用于分析3D细胞和细胞核形态。我们使用3D点云输入,在单细胞和群体水平上捕捉形态学特征,并考虑表型异质性。我们将这些方法应用于超过95,000个经临床相关及细胞骨架调控的化学和遗传扰动处理的黑色素瘤细胞。该流程准确预测了药物扰动和细胞状态。我们的框架揭示了与扰动相关的细微形态变化、与信号活动相关联的关键形状,以及对细胞状态异质性的可解释性见解。MorphoMIL表现出卓越的性能,并在多样化数据集上具有良好的泛化能力,为药物发现中的可扩展、高通量形态学分析铺平了道路。该论文透明同行评审过程的记录包含在补充信息中。
