Xenium Spatial Transcriptomics of Head and Neck Single Cell Carcinoma

ABSTRACT: Recent work has shown that the spatial organization of immune responses is a critical determinant of anti-tumor immunity. Here, we profiled ten head and neck squamous cell carcinoma (HNSCC) patient tumors and one ameloblastoma tumor using Xenium V1 spatial transcriptomics. The 10X genomics human multi-tissue and cancer gene expression panel targeting 377 genes was used in combination with 100 custom Xenium probes targeting patient-specific CDR3 regions of T cell receptors (TCRs) in T cells, additoinal T cell specific genes, HPV oncoprotein genes, and tumor genes of interest. This enabled the detection of 477 transcripts within each tumor sample at a single-cell resolution. For seven of the ten HNSCC samples, different tissue sections run on different days were analyzed as technical replicates. Together, these findings introduce a scalable platform for spatial clonal T cell analysis and provide new insight into the spatial relationship of cells within the HNSCC tumor microenvironment.

Distinct cellular and spatial niches within the inflamed synovium of childhood arthritis [xenium]

Project description:Precision use of targeted therapies is urgently needed to improve long-term clinical outcomes for children affected by inflammatory arthritis, known as Juvenile Idiopathic Arthritis. Progress has been obstructed by a lack of understanding of the cellular basis of joint inflammation in children, given the difficulties in obtaining and studying synovial tissue itself. To this end, we combine single-cell RNA-sequencing, multiplexed immunofluorescence imaging and spatial transcriptomics to define the cellular and transcriptomic landscape of the synovium in children with Juvenile Idiopathic Arthritis. We identify spatial niches of resident and infiltrating cell populations that correlate with the degree of inflammation, and gene programs associated with arthritis severity. Combined with analyses of synovial fluid and peripheral blood from the same children, we distinguish differences in cellular composition, signalling pathways and transcriptional programs across anatomical compartments. Whilst we identify several pathogenic populations shared with adult-onset arthritis, our analyses highlight increased vascularity of the inflamed developing joint and TGFb-driven stromal subsets that upregulate expression of disease risk-associated genes. Overall, these findings illustrate the need for treatment algorithms informed by a tissue-based classification of arthritis. Slides were prepared, processed, imaged and underwent post-run staining according to Xenium (10X Genomics) protocols: “CG000580 Rev C”, “CG000582 Rev D”, “CG000584 Rev B” and “CG000613 Rev A”, according to manufacturer’s instructions. For gene detection, slides hybridized with probes from the predesigned Xenium Human Multi-Tissue and Cancer Gene Expression and hMulti_v1 design (chemistry v1: 10x Genomics), consisting of 377 genes was used.

Single-cell RNA-sequencing of HNSCC-infiltrating T cells

Project description:This study examines the T cell landscape in head and neck squamous cell carcinoma (HNSCC) using single-cell RNA sequencing combined with T cell receptor and protein profiling. By analyzing tumor-infiltrating T cells from 28 patients, we identified diverse T cell subsets, characterized their transcriptional states, and mapped their clonal dynamics. These findings provide a detailed view of the immune microenvironment in HNSCC and offer insights into T cell-mediated immunity and potential targets for immunotherapy and are patient-matched to PBMC TCR sequencing and Xenium spatial transcriptomics in separate GEO submissions.

A Single-Cell Atlas Of Human Pediatric Liver Reveals Age-Related Hepatic Gene Signatures

Project description:To investigate the spatial dynamics of immune cells in the liver, particularly myeloid cells, we utilized the Xenium spatial transcriptomics platform to examine gene zonation patterns in pediatric and adult livers. We explored the expression of 477 genes in two pediatric and three adult livers (one adult sampled 3 times, for a total of 7 Xenium samples). Our analysis revealed significant zonation of gene expression within Kupffer cells (KC-like). The zonation of KC-like marker genes suggests that the differential gene expression observed in the dissociated pediatric liver map may be due to shifts in the spatial organization of KC-like cells in the pediatric liver. These findings underscore the importance of spatial transcriptomics in understanding age-related differences in immune cell behavior within the liver and provide new insights into the complex spatial dynamics of myeloid cells in pediatric versus adult livers.

Xenium data for a comparison of spatial transcriptomics technologies for medulloblastoma cryosections

Project description:10X Genomics Xenium data from human Medulloblastoma samples. The data was acuired in the course of a study performing a comparison of four imaging-based ST methods – RNAscope HiPlex, Molecular Cartography, MERFISH/Merscope, and Xenium – together with sequencing-based ST (Visium). These technologies were used to study cryosections of medulloblastoma with extensive nodularity (MBEN), a tumor chosen for its distinct microanatomical features. Our analysis reveals that automated imaging-based ST methods are well suited to delineating the intricate MBEN microanatomy, capturing cell-type-specific transcriptome profiles. We devise approaches to compare the sensitivity and specificity of the different methods together with their unique attributes to guide method selection based on the research aim. Furthermore, we demonstrate how reimaging of slides after the ST analysis can markedly improve cell segmentation accuracy and integrate additional transcript and protein readouts to expand the analytical possibilities and depth of insights. This study highlights key distinctions between various ST technologies and provides a set of parameters for evaluating their performance. Our findings aid in the informed choice of ST methods and delineate approaches for enhancing the resolution and breadth of spatial transcriptomic analyses, thereby contributing to advancing ST applications in solid tumor research.

Spatial transcriptomic analysis of human dorsoal root ganglia neurons [Xenium]

Project description:Xenium platform was used for the spatial transcriptomic analysis of human DRG neurons, 100 marker genes were selected as the customized probe panel and hybridized to fresh frozen hDRG sections. Manual segmentation of each neuron soma was performed, based on expressions of pan-neuronal marker gene PGP9.5, satellite glia cell marker FAB7B, and the corresponding H.E. staining. In total, 1340 neurons were identified (excluding 75 region-of-interest with poor or unclear neuronal soma morphology in H & E staining) and clustered into 16 groups. The 16 clusters were assigned as different cell types based on marker genes expression.
