下丘脑控制基本的社会行为和内环境平衡功能。然而,下丘脑核团的细胞结构,包括不同类型细胞的分子同一性、空间组织和功能,还知之甚少。在这里,我们开发了一种基于成像的原位细胞类型识别和映射方法,并将其与单细胞RNA测序相结合,创建了小鼠下丘脑视前区的分子注释和空间分辨细胞图谱。我们描绘了大约100万个细胞,鉴定了大约70个具有不同神经调节特征和空间组织特征的神经元群体,并定义了在雄性和雌性小鼠的社会行为中激活的特定神经元群体,为行为回路的机械研究提供了一个高分辨率的框架。所描述的方法为在不同组织和生物体中建立细胞图谱开辟了一条新的途径。单细胞原位基因表达谱揭示了小鼠下丘脑视前区神经元的分子同一性、空间组织和功能。
The hypothalamus controls essential social behaviors and homeostatic functions. However, the cellular architecture of hypothalamic nuclei, including the molecular identity, spatial organization, and function of distinct cell types, is poorly understood. Here, we developed an imaging-based in situ cell type identification and mapping method and combined it with single-cell RNA-sequencing to create a molecularly annotated and spatially resolved cell atlas of the mouse hypothalamic preoptic region. We profiled ~1 million cells, identified ~70 neuronal populations characterized by distinct neuromodulatory signatures and spatial organizations, and defined specific neuronal populations activated during social behaviors in male and female mice, providing a high-resolution framework for mechanistic investigation of behavior circuits. The approach described opens a new avenue for the construction of cell atlases in diverse tissues and organisms. In situ gene expression profiling of single cells reveals the molecular identity, spatial organization and function of neurons in the mouse hypothalamic preoptic region.
