摘要
En 中文
空间转录组学(ST)将基因表达数据与细胞的时空组织及其相关的组织学相结合,为组织生物学提供了前所未有的见解。虽然现有方法纳入了基于位置或组织学信息,但没有一种方法能在统一框架内完全协同基因表达、组织学特征和精确的空间坐标。此外,这些方法在多样数据集和条件下往往表现出不一致的性能。在此,我们介绍了stImage,一个开源的R软件包,为ST分析提供了全面且灵活的解决方案。通过生成深度学习衍生的组织学特征并提供54种整合策略,stImage无缝地结合了转录组谱、组织学图像和空间信息。我们通过多个数据集展示了stImage的有效性,强调了其利用诊断图指导用户选择最合适整合策略的能力。我们的结果表明,stImage能够优化ST,持续提升生物学见解,并加深我们对组织结构的理解。stImage可免费获取于https://github.com/YuWang-VUMC/stImage。
