用AI一次成像识别两个细胞结构,让显微镜实时观察更准更快。

Interpretable deep learning illuminates multiple structures fluorescence imaging: a path toward trustworthy artificial intelligence in microscopy

  • 通过注意力机制和亮度自适应层,从单图同时预测两个细胞结构。
  • 相比传统方法,成像质量提升30%以上,成像速度翻倍。
  • 模型结果可解释,适合需要可信AI的生物医学研究者。

活细胞中多亚细胞结构的成像对理解细胞动态至关重要。然而,传统的多色序列荧光显微技术存在显著成像延迟且可标记的结构数量有限,严重限制了实时活细胞研究的应用。本文提出自适应可解释多结构网络(AEMS-Net),一种深度学习框架,能仅凭一张图像同时预测两个亚细胞结构。该模型通过整合注意力机制与亮度自适应层,对染色强度进行归一化并突出关键图像特征。借助科尔莫戈罗夫-阿诺德表示定理,模型将学习到的特征分解为可解释的一元函数,增强了复杂亚细胞形态的可解释性。我们证明AEMS-Net实现了线粒体与微管间相互作用的实时记录,所需成像流程仅为传统序列通道方式的一半。显著地,该方法相比传统深度学习方法在成像质量上提升超过30%,建立了一种新的长期、可解释的活细胞成像范式,推动了对亚细胞动态的探索能力。

原文摘要 · Abstract (English)

Live-cell imaging of multiple subcellular structures is essential for understanding subcellular dynamics. However, the conventional multi-color sequential fluorescence microscopy suffers from significant imaging delays and limited number of subcellular structure separate labeling, resulting in substantial limitations for real-time live-cell research applications. Here, we present the Adaptive Explainable Multi-Structure Network (AEMS-Net), a deep-learning framework that enables simultaneous prediction of two subcellular structures from a single image. The model normalizes staining intensity and prioritizes critical image features by integrating attention mechanisms and brightness adaptation layers. Leveraging the Kolmogorov-Arnold representation theorem, our model decomposes learned features into interpretable univariate functions, enhancing the explainability of complex subcellular morphologies. We demonstrate that AEMS-Net allows real-time recording of interactions between mitochondria and microtubules, requiring only half the conventional sequential-channel imaging procedures. Notably, this approach achieves over 30% improvement in imaging quality compared to traditional deep learning methods, establishing a new paradigm for long-term, interpretable live-cell imaging that advances the ability to explore subcellular dynamics.
