1282-CODA:空间转录组跨样本对齐与差异分析框架

from 聊聊Sci

该研究介绍了一种名为 CODA 的空间转录组学集成分析框架,旨在解决不同样本、不同技术平台间数据对齐与比较的挑战。由于组织处理会导致样本产生非线性形变及有限的空间重叠,CODA 通过在共享的低维潜空间内执行全局仿射对齐、Transformer 特征匹配以及局部非线性优化,实现了跨样本的精准对齐。在此基础上,该工具引入了空间互相关指标,能够系统性地识别在不同实验条件下空间分布保持一致(SCG)或发生显著偏移(SDG)的基因。基准测试表明,CODA 在对齐精度、计算速度和内存效率方面均优于现有方法,能有效揭示与疾病进展及生理调节相关的空间表达模式。此外,该框架支持三维组织架构重构,并证明了空间基因分析结果对网格分辨率和表达水平具有高度的鲁棒性。References:Tan Y, Wang Z, Wang A, et al.
