自动化单细胞成像分析平台,让生物研究高效处理海量活细胞影像数据。

acia-workflows: Automated Single-cell Imaging Analysis for Scalable and Deep Learning-based Live-cell Imaging Analysis Workflows

  • 基于深度学习的模块化图像分析流水线,支持8种分割与追踪方法。
  • 整合代码、依赖、文档与可视化于一个Jupyter Notebook,实现可复现分析。
  • 提供10余个开源应用模板,适合微流控活细胞实验的定量分析。

活细胞成像(LCI)技术可在单细胞层面实现对活细胞时空特征的精细表征,对生命科学研究(从生物医学到生物工艺)至关重要。高通量设置可并行培养数十至数百个细胞,带来稳健且可重复的洞察。然而,每个实验产生的大量LCI数据使这些洞察被掩盖。近年来,先进的深度学习方法在细胞分割与追踪方面取得进展,使大规模数据自动化分析成为可能,为系统研究单细胞动态提供了前所未有的机会。当前的关键挑战在于将这些强大工具整合为易用、灵活且用户友好的分析工作流,以支持生物学研究中的常规应用。本文提出acia-workflows平台,包含三个核心组件:(1) 自动化活细胞成像(acia)Python库,支持模块化设计图像分析流水线,集成八种深度学习分割与追踪方法;(2) 工作流将分析流水线、软件依赖、文档和可视化整合至单一Jupyter Notebook,实现可访问、可复现、可扩展的分析流程;(3) 一系列应用工作流,展示真实场景下的分析与定制能力。具体包括三个工作流,用于分析微流控LCI实验,涵盖生长率比较及在氧气变化下个体细胞动态响应的分钟级定量分析。该平台提供超过十个开源应用工作流,公开获取于https://github.com/JuBiotech/acia-workflows。

原文摘要 · Abstract (English)

Live-cell imaging (LCI) technology enables the detailed spatio-temporal characterization of living cells at the single-cell level, which is critical for advancing research in the life sciences, from biomedical applications to bioprocessing. High-throughput setups with tens to hundreds of parallel cell cultivations offer the potential for robust and reproducible insights. However, these insights are obscured by the large amount of LCI data recorded per experiment. Recent advances in state-of-the-art deep learning methods for cell segmentation and tracking now enable the automated analysis of such large data volumes, offering unprecedented opportunities to systematically study single-cell dynamics. The next key challenge lies in integrating these powerful tools into accessible, flexible, and user-friendly workflows that support routine application in biological research. In this work, we present acia-workflows, a platform that combines three key components: (1) the Automated live-Cell Imaging Analysis (acia) Python library, which supports the modular design of image analysis pipelines offering eight deep learning segmentation and tracking approaches; (2) workflows that assemble the image analysis pipeline, its software dependencies, documentation, and visualizations into a single Jupyter Notebook, leading to accessible, reproducible and scalable analysis workflows; and (3) a collection of application workflows showcasing the analysis and customization capabilities in real-world applications. Specifically, we present three workflows to investigate various types of microfluidic LCI experiments ranging from growth rate comparisons to precise, minute-resolution quantitative analyses of individual dynamic cells responses to changing oxygen conditions. Our collection of more than ten application workflows is open source and publicly available at https://github.com/JuBiotech/acia-workflows.
