CELL:Allen发布单细胞分辨率的小鼠3D脑图谱

2020-05-08 MedSci原创 MedSci原创

最近的大规模合作正在产生小鼠大脑中的细胞类型和连接的主要研究,收集了大量跨模式、空间尺度和脑区的数据。这些数据的成功整合需要一个标准的三维参考图集。

最近的大规模合作正在产生小鼠大脑中的细胞类型和连接的主要研究,收集了大量跨模式、空间尺度和脑区的数据。这些数据的成功整合需要一个标准的三维参考图集。

最近,研究人员提出的艾伦小鼠脑共同坐标框架(CCFv3)就是一个这样的资源。

在1675只年轻的成年C57BL/6J小鼠中,通过整合高分辨率的平面内序列双光子断层扫描图像与100μm的z-sampling技术,研究人员构建了一个具有10μm体素分辨率的平均模板大脑。

然后,使用多模态参考数据,研究人员直接对整个大脑进行了三维细分,标记了每一个脑室,包括43个等皮层区域及其分层、329个皮层下灰质结构、81个纤维束和8个脑室结构。

CCFv3可用于分析、可视化,整合多模态和多尺度的三维数据集,并可公开访问(https://atlas.brain-map.org/)。
