Abstract

Understanding the diversity of gastrointestinal (GI) immune cells, especially in the muscularis propria, is crucial for understanding their role in the maintenance of enteric neurons and smooth muscle and their contribution to GI motility. Here, we present a detailed protocol for isolating single immune cells from the human gastric muscularis propria. We describe steps for tissue preservation, dissection, and dissociation of the muscularis propria. We then detail procedures for magnetic sorting of CD45 cells and single-cell RNA sequencing (scRNA-seq) analysis. For complete details on the use and execution of this protocol, please refer to Chikkamenahalli et al..

摘要

了解胃肠道(GI)免疫细胞的多样性,特别是在固有肌层中的多样性,对于理解它们在维持肠神经元和平滑肌中的作用以及它们对 GI 运动的贡献至关重要。在这里,我们提供了一个从人胃固有肌层中分离单个免疫细胞的详细方案。我们描述了组织保存、解剖和固有肌层解离的步骤。然后,我们详细介绍了 CD45 细胞的磁分选和单细胞 RNA 测序(scRNA-seq)分析的步骤。有关此方案的使用和执行的完整详细信息,请参阅 Chikkamenahalli 等人的研究。
