1228-GEMINI:记录细胞动态历史的基因编码组装体

from 聊聊Sci

这项研究介绍了一种名为 GEMINI 的基因编码细胞活动记录系统,它利用蛋白质自组装技术在活细胞内构建出类似“树轮”的微型存储装置。该系统能将细胞的生理信号和转录动态转化为同心圆状的荧光图案,从而实现对细胞历史的高精度回溯分析。相较于传统的线性记录器,GEMINI 的球状生长模式不仅减少了对细胞功能的机械干扰,还使成像读数更加自动化且不受细胞方向影响。实验证明,该技术能以小时级的时间分辨率记录炎症反应和神经元活动,并能准确反映信号强度的差异。通过在小鼠异种移植模型和大脑中的应用,研究者成功绘制了组织内部复杂的时空信号图谱。总而言之,GEMINI 为研究复杂组织在发育、疾病及再生过程中的细胞动态规律提供了一种功能强大的新型工具。References:Yan Y, Lu J, Li Z, et al.
