039-扰动细胞和组织图谱:因果生物学基础模型

04 Aug 2025

Description

这些研究聚焦于细胞和组织生物学的因果基础模型,旨在通过高通量扰动筛选和人工智能/机器学习(AI/ML)技术来理解复杂的分子回路。文章讨论了诸如Perturb-seq和光学池化筛选(OPS)等实验方法如何从单一表型读取发展到高内容、多模态的读数,从而能更全面地捕捉细胞状态。随着实验规模的扩大和计算能力的增强,特别是在处理非线性遗传相互作用方面,现在有可能构建能够预测未测试扰动结果的生成模型。最终,这些进展为创建一个全面的扰动细胞图谱奠定了基础,该图谱将补充现有的观测性人类细胞图谱,并统一我们对基因、细胞和组织运作方式的理解,从而推动生物学和医学的发现。References: Rood J E, Hupalowska A, Regev A.
