    MIT 团队用 AI 模型 IRIS 解码细胞通信语言

    MIT 与 Whitehead 研究所团队开发出神经网络模型 IRIS,能识别不同信号通路在细胞基因活动中留下的独特“指纹”,并据此推断细胞在胚胎发育各阶段接收过哪些信号。相关成果 9 月 8 日发表于 Nature Methods,IRIS 借助迁移学习可跨细胞类型工作,甚至能预测未曾见过的细胞类型。研究者用小鼠胚胎原肠胚期单细胞验证了该模型,并据此预测出促进肺发育的信号组合,经小鼠胚胎实验证实。

    searchers employed IRIS to identify signals needed to create a cell type critical for lung development, the model predicted that activating a specific signaling pathway would encourage lung-specific development. Experiments in mouse embryos confirmed the model’s prediction. By identifying the precise combinations of signals that drive lung cell development, they can more reliably generate accurate, lab-grown models of lung tissue. “In these ways, IRIS is helping us decode the language cells use
