[Abstract]  Our protocol describes a simple procedure for isolating stromal cells from lymph nodes (LN). LN are disrupted then enzymatically digested with collagenase and dispase to produce a single cell suspension that can be stained with fluorescently labelled antibodies and analysed by flow cytometry. This protocol will enable identification of fibroblastic reticular cells (FRC), lymphatic endothelial cells (LEC), blood endothelial cells (BEC) as PNAd+ BEC that form LN high endothelial venules (HEV). This method can be applied to examine LN stromal cell responses during inflammatory events induced by infections or immunologic adjuvants and to subset most leukocytes found in LN. [摘要]  我们的方案描述了从淋巴结(LN)分离基质细胞的简单过程。 LN被破坏,然后用胶原酶和分散酶酶消化以产生可以用荧光标记的抗体染色的单细胞悬浮液并通过流式细胞术分析。 该方案能够识别形成LN高内皮小静脉(HEV)的PNAd + BEC的成纤维细胞网状细胞(FRC),淋巴内皮细胞(LEC),血液内皮细胞(BEC)。 该方法可以用于检测由感染或免疫佐剂诱导的炎症事件期间的LN基质细胞反应,并且在LN中发现大多数白细胞。
【背景】淋巴结(LN)由间充质和内皮基质细胞的复杂网络构成。这些包括成纤维细胞网状细胞(FRCs),淋巴内皮细胞(LECs)和血液内皮细胞(BECs)。这些基质细胞组织了LN的复杂微结构,使得能够支持免疫细胞迁移,体内平衡,耐受性和细胞相互作用,以引发对病原体和肿瘤的免疫应答。我们已经表明,LN基质细胞可以响应于炎症信号而增殖和扩张,并且将免疫细胞募集到伴随感染的LN中(Gregory等,2017)。这些基质细胞也可以显着调节其转录程序以应对感染,从而支持持续的免疫应答。该方案使稳定状态和疾病期间LN的基质细胞亚群可靠地分离。这使得LN基质细胞的表型,功能,遗传或表观遗传学研究揭示了它们如何有助于组织体内平衡和免疫应答。
