330-COAST:基于图像的多模态组织切片配准

from 聊聊Sci

该研究介绍了 COAST(连续多组学空间组织对齐)这一新型计算方法,旨在精确对齐连续的多模态组织切片。与需要匹配分子特征的现有方法不同,COAST 仅通过分析与空间数据相关的配对染色图像来实现对齐,从而扩大了其适用范围。它利用一个视觉变换器 (ssDINO) 从这些图像中提取结构信息,以便在不同模态间建立一个共享的坐标框架。对空间转录组学数据集的测试表明,COAST 在保持组织结构的同时,其性能可与既有的单模态工具媲美或超越。此外,该方法还成功应用于整合小鼠肾脏缺血再灌注损伤模型的空间转录组学和代谢组学/脂质组学数据。总而言之,COAST 提供了一个强大且灵活的流程,无需依赖分子特征或预先注释,即可实现关键的多模态空间数据集成。References: Image-guided alignment of consecutive multi-modal tissue slides前往小宇宙评论区与主播互动
