摘要 Abstract

中文摘要
全转录组空间分析在回答复杂生物学问题方面的潜力,常常受到其庞大的计算和分析需求的制约。随着细胞、样本和检测通量(plex)数量的增加,这些计算挑战叠加,形成瓶颈,减缓了发现的步伐。此外,这些复杂数据集通常需要专业的数据分析专长,可能进一步减缓从“数据到洞见”的过程。为弥合这一鸿沟,我们创建了一种新的分析范式,使分析专长较少的生物学家和研究人员能够直接与其数据交互,以快速、对话式且易于使用的工作流进行深入的假设驱动分析。在本演示中,我们讨论了重新构想的AtoMx®空间信息学平台(SIP)中即将推出及正在开发的三项进展,并重点介绍在一个公开可用的结肠腺癌FFPE WTX样本中发现的结果。首先,我们重新设计了架构,目标是将生物学置于核心地位,使研究人员能够快速观察、提出假设并迭代学习。其次,一个敏捷的计算引擎,利用在>10亿个空间解析单细胞上训练的基础模型,自动完成细胞注释,将分析时间从数天缩短至数小时。第三,该工作流生成一个精心整理的汇总表格包,其体积比完整数据集小数千倍,但远比人工生成的提示更为丰富。一旦LLM摄入该数据包,即可回答关于该数据集的各种问题,例如“肿瘤细胞中哪些通路具有空间可变性?”或“T细胞在该组织中所处的空间背景是什么?”我们将此方法应用于结肠样本(412,052个细胞)。我们的基础模型自动完成了细胞分型和空间域分配,为分析奠定了基础。随后我们应用了LLM对话工作流。初始查询快速识别出占主导地位的促肿瘤信号(EGFR、TGF-beta、MAPK)以及降低的促凋亡TRAIL通路。随后一个“对话式”查询以寻找分子驱动因素,识别出显著的MIF(肿瘤)与CD74(TAM)配体-受体相互作用,为所观察到的MAPK活性提供了直接的机制联系。整个工作流从自动细胞分型到机制洞见迅速完成,并生成了所有可重现的图表,展示了一个无需专家级编码能力的完整“分析到可视化”流程。总之,AtoMx® SIP成功弥合了复杂空间数据与生物学洞见之间的鸿沟。这一新范式使全转录组分析大众化,使研究人员无需深厚的计算专长即可进行快速、迭代、假设驱动的发现。

The potential of whole-transcriptome spatial analysis to answer complex biological questions is often hindered by the sheer weight of its computational and analytical demands. As the number of cells, samples, and plex increases these computational challenges are compounded resulting in bottlenecks that slow the pace of discovery. Moreover, these complex datasets often require specialist data analysis expertise that can further slow “data-to-insight”. To bridge this gap, we created a new analysis paradigm that enables biologists and researchers with less analytical expertise to interact with their data directly, performing deep hypothesis-driven analysis in a rapid, conversational and accessible workflow. In this presentation we discuss three advancements arriving in the reimagined AtoMx ® Spatial Informatics Platform (SIP) and in development and highlight results found in a publicly available colon adenocarcinoma FFPE WTX sample. First, we have redesigned the architecture with the goal of putting biology front and center, allowing researchers to quickly observe, hypothesize, and learn iteratively. Second, an agile computational engine, leveraging a foundational model trained on >1 billion spatially-resolved single cells, automates cell annotations, reducing analysis time from days to hours. Third, this workflow creates a carefully-curated package of summary tables, thousands of times smaller than a full dataset, but far richer than a human-generated prompt. Once an LLM ingests this package, it stands ready to answer diverse questions about the dataset, e.g. “what pathways are spatially variable in tumor cells?”, or “what are the spatial contexts T cells inhabit in this tissue?” We applied this approach to the colon sample (412,052 cells). Our foundational model automated cell typing and spatial domain assignment, providing the basis for the analysis. We then applied the LLM chat workflow. An initial query rapidly identified the dominant pro-tumoral signatures (EGFR, TGF-beta, MAPK) and reduced pro-apoptotic TRAIL pathway. A follow-up “conversational” query for molecular drivers identified a significant MIF (tumor) to CD74 (TAM) ligand-receptor interaction, providing a direct mechanistic link to the observed MAPK activity. This entire workflow from automated cell typing to mechanistic insight was completed rapidly and generated all reproducible figures, demonstrating a complete analysis-to-visualization pipeline that does not require expert coding abilities. In conclusion, the AtoMx ® SIP successfully bridges the gap between complex spatial data and biological insight. This new paradigm democratizes whole-transcriptome analysis, enabling researchers to conduct rapid, iterative, hypothesis-driven discovery without deep computational expertise.
