Project description:C57BL/6 mouse lymph node stromal cells were isolated for scRNA-seq, more than 2x104 cells were run on the 10X Chromium Controller (10X Genomics) to partition single cells with uniquely barcoded beads and processed for sequencing library preparation using the Chromium Single Cell 3’ Reagent Kit. cDNA libraries were sequenced on a NovaSeq 6000 sequencing system. 4 x 103 cells per sample were captured on the 10X Chromium chip. 5-10 x 104 reads/cell were obtained with characterization of 2-3 x 103 transcripts/cell.

Project description:Tissue structure of the lymph node (LN) is supported by the network of stromal cells of mesenchymal origin, which is suggested to contribute to various immunological processes. In order to identify stromal cell–derived factors that regulate immune function, we performed gene expression profiling of stromal cells freshly isolated from collagenase digested mouse LNs, cultured stromal cell lines, and embryonic fibroblasts as a mesenchymal control.

In order to identify stromal cellM-bM-^@M-^Sderived factors that regulate immune function, we performed gene expression profiling of stromal cells freshly isolated from collagenase digested mouse LNs, cultured stromal cell lines, and embryonic fibroblasts as a mesenchymal control. Total RNAs extracted from the CD45-CD31-podoplanin+VCAM-1+ stromal cell fraction was sorted from enzymatically digested mouse LNs, cultured stromal cell lines stimulated with or without lymphotoxin (LTM-NM-2R agonistic antibody), and mouse embryonic fibroblasts (MEFs) were used for microarray analysis to assess relative gene expression.

Project description:Despite their key role in immunity our understanding of primary and secondary lymphoid stromal cell heterogeneity and ontogeny remains limited. Here, using genome-wide expression profiling and phenotypic and localization studies, we identify a functionally distinct subset of BP3-PDPN+PDGFRβ+/α+CD34+ stromal adventitial cells in both lymph nodes and thymus that is located within the perivascular niche surrounding PDPN-PDGFRβ+/α-Esam-1+ITGA7+ pericytes. In re-aggregate organ grafts adult CD34+ adventitial cells gave rise to multiple thymic and lymph node mesenchymal subsets including pericytes, FRC-, MRC- and FDC-like cells, the development of which was lymphoid environment dependent. During thymic ontogeny pericytes developed from a transient population of BP3-PDPN+PDGFRβ+/α+CD34-/lo anlage-seeding progenitors that subsequently up-regulated CD34 and we provide evidence suggesting that similar embryonic progenitors give rise to lymph node mesenchymal subsets. These findings extend the current understanding of lymphoid mesenchymal cell heterogeneity and highlight a role of the CD34+ vascular adventitia as a potential ubiquitous source of lymphoid stromal precursors in postnatal tissues. To comprehensively study the differences and similarities between mesenchymal stromal subsets in the thymus and lymph nodes, global gene expression analysis was performed on sorted PDPN-, BP-3-PDPN+ and BP-3+PDPN+ PDGFRb+ lymph node mesenchymal cells (LNMC) as well as PDPN- and BP-3-PDPN+ PDGFRb+ thymic mesenchymal cells (TMC) from 2 w old mice by microarray. Total RNA was prepared from TMC and LNMC (pooled inguinal, brachial and axillary LN) subsets sorted from 3 (TMC) and 10-11 (LNMC) 2 weeks old mice per experiment. Isolated RNA from 3 individual experiments was amplified and prepared for hybridization to the Affymetrix Mouse Gene 1.1 ST Array at a genomics core facility: Center of Excellence for Fluorescent Bioanalytics (KFB, University of Regensburg, Germany)

Project description:Fate mapping and scRNA sequencing reveal origin and diversity of lymph node stromal precursors

Project description:Lymph node (LN) stromal cells play a crucial role in LN development and in supporting adaptive immune responses. However, their origin, differentiation pathways, and transcriptional programs are still elusive. Here, we used lineage-tracing approaches and single-cell transcriptome analyses to determine origin, transcriptional profile, and composition of LN stromal and endothelial progenitors. Our results showed that all major stromal cell subsets and a large proportion of blood endothelial cells originate from embryonic Hoxb6+ progenitors of the lateral plate mesoderm (LPM), whereas lymphatic endothelial cells arise from Pax3+ progenitors of the paraxial mesoderm (PXM). Single-cell RNA sequencing revealed the existence of different Cd34+ and Cxcl13+ stromal cell subsets and showed that embryonic LNs contain proliferating progenitors possibly representing the amplifying populations for terminally differentiated cells. Taken together, our work identifies the earliest embryonic sources of LN stromal and endothelial cells and demonstrates that stromal diversity begins already during LN development.

Project description:Using a mouse model of breast cancer that develops spontaneous lymph node metastasis, we performed high-resolution single-cell RNA sequencing (scRNA-Seq) of the primary tumor and TDLN to measure how cancer cells adapt to the dynamic lymph node microenvironment. To understand the dynamic change of lymph node microenvironment after cancer cell invasion, we also compared the gene-expression alteration between naive lymph node and TDLN at single-cell level.
