用视频预测癌细胞命运,提前10小时就能判断生死。

Understanding Cell Fate Decisions with Temporal Attention

  • 直接从原始视频学细胞命运,不依赖预设特征。
  • 准确率达94%,提前10小时即可可靠预测。
  • 揭示形态与p53信号如何影响细胞生死决策。

理解非遗传因素对细胞命运的影响对开发和改进癌症治疗至关重要,因为基因相同的细胞在相同治疗条件下可能表现出不同结果。本文提出一种深度学习方法,基于化疗处理下癌细胞群体的长期活细胞录像进行细胞命运预测。我们的Transformer模型直接从原始图像序列预测细胞命运,无需依赖预定义的形态或分子特征。除了分类任务,我们还引入了一个全面的可解释性框架,用于解析模型预测所依赖的时间与形态线索。结果显示,仅凭视频即可实现细胞结局预测,模型达到平衡准确率0.94和F1分数0.93。注意力与掩码实验表明,决定命运的信号并非仅存在于轨迹末帧,可靠预测可在事件发生前长达10小时实现。分析揭示了有丝分裂与凋亡序列中预测信息的时间分布差异,以及细胞形态与p53信号在决定细胞命运中的作用。这些发现表明,基于注意力的时序模型不仅实现了精准预测,还提供了关于细胞决策中非遗传决定因素的生物可解释洞察。代码已公开于https://github.com/bozeklab/Cell-Fate-Prediction。

原文摘要 · Abstract (English)

Understanding non-genetic determinants of cell fate is critical for developing and improving cancer therapies, as genetically identical cells can exhibit divergent outcomes under the same treatment conditions. In this work, we present a deep learning approach for cell fate prediction from raw long-term live-cell recordings of cancer cell populations under chemotherapeutic treatment. Our Transformer model is trained to predict cell fate directly from raw image sequences, without relying on predefined morphological or molecular features. Beyond classification, we introduce a comprehensive explainability framework for interpreting the temporal and morphological cues guiding the model's predictions. We demonstrate that prediction of cell outcomes is possible based on the video only, our model achieves balanced accuracy of 0.94 and an F1-score of 0.93. Attention and masking experiments further indicate that the signal predictive of the cell fate is not uniquely located in the final frames of a cell trajectory, as reliable predictions are possible up to 10 h before the event. Our analysis reveals distinct temporal distribution of predictive information in the mitotic and apoptotic sequences, as well as the role of cell morphology and p53 signaling in determining cell outcomes. Together, these findings demonstrate that attention-based temporal models enable accurate cell fate prediction while providing biologically interpretable insights into non-genetic determinants of cellular decision-making.
