OVERVIEW

The Center for Spatial Omics (CSO) at St. Jude, established as part of the 2022-2027 Strategic Plan, is a shared resource that uses advanced spatial omics platforms to study cell interactions and organization in tissues at single-cell resolution while maintaining tissue architecture. The CSO utilizes various spatial omics assays and instrumentation to advance discoveries in catastrophic childhood diseases.

IMPACT

The Center of Spatial Omics (CSO) enables high-resolution, highly multiplexed spatial analysis of gene and protein expression within intact tissues, providing St. Jude investigators with access to molecular information at a scale and level of context not achievable with conventional approaches. The Center uniquely supports simultaneous measurement of hundreds to thousands of RNA targets—up to whole-transcriptome profiling—as well as high-plex protein detection ranging from tens to over a thousand markers in a single experiment. This depth of multiplexing allows comprehensive mapping of cellular states, signaling pathways, and cell–cell interactions within complex tumor and tissue microenvironments. By integrating advanced spatial platforms with expert study design, standardized workflows, and end-to-end analytical support, the center enhances rigor and reproducibility and accelerates high-impact basic, translational, and clinical research across St. Jude.

Data analysis services

Primary processing and pipeline development

  •  Automated, high-performance pipelines for image processing, cell segmentation, and molecular quantification across technologies.

Quality control (QC)

  • Filtering and normalization, monitoring metrics such as feature counts, UMI distributions, and tissue integrity to ensure data reliability.

Cell-type deconvolution and annotation

  • Integration of spatial transcriptomics with single-cell RNA-seq (scRNA-seq) references to resolve cell identities and map their precise locations. This includes both reference-based label transfer and de novo annotation of novel cellular states within the tissue architecture.

Advanced spatial analytics

  • Investigation of the "spatial connectome," including cell-cell interaction analysis, neighborhood/niche identification, and spatial trajectory inference.

Multi-omic integration

  • Computational strategies to merge transcriptomic, proteomic, and epigenetic layers, providing a unified view of the tissue microenvironment.

Interactive visualization and support

  • Delivery of data in user-friendly formats and interactive dashboards, coupled with expert consultation to help investigators interpret complex spatial patterns.
