研究人员开发空间转录组生物组织亚结构解析新工具
空间转录组 生物组织 亚结构解析 新工具
2023/1/5
近年来，空间转录组学（Spatial Transcriptomics，简称ST）的突破性进展使得研究人员在全基因组层面测量组织切片中特定空间位点的基因表达信息成为可能，这为研究人员破译组织的空间结构，理解复杂的生物学功能提供了条件。组织切片中具有相似基因表达空间模式的区域形成组织中特异的亚结构（简称为空间域）。精确破译空间域是空间转录组数据解析中最基本和关键的环节。然而，适用于单细胞异质性识别的经...

Protection Mutualisms and the Community: Geographic Variation in an Ant-Plant Symbiosis and the Consequences for Herbivores
Ant-plant mutualism Azteca context
2015/12/10
Protection mutualisms mediate trophic interactions in many systems, but their effects
on the surrounding community are rarely studied. Ant-plant symbioses are classic
examples of protection mutual...
