Spatial Transcriptomics Services
Utilize 10x Genomics Visium CytAssist to generate high-resolution spatial gene expression profiles from FFPE or fresh-frozen sections, enabling detailed characterization of tumor microenvironments, neural circuits, and immune microenvironments.
Why Spatial Transcriptomics Matters

Spatial transcriptomics merges spatial gene expression profiling with intact tissue architecture, preserving microanatomical detail and capturing mRNA in situ for comprehensive transcriptome mapping. Using the 10x Genomics Visium CytAssist spatial platform, our high-throughput spatial transcriptomic analysis supports both FFPE spatial transcriptomics and fresh-frozen spatial profiling, delivering spatially resolved transcriptomics data across entire tissue sections.
This approach complements bulk RNA-seq, which measures average expression across all cells, and single-cell RNA-seq, which resolves cellular heterogeneity but requires tissue dissociation, by retaining the exact location of each transcript for accurate in situ analysis.
- Map tumor microenvironment interactions with spatial gene expression profiling to uncover immune exclusion patterns and stromal signaling
- Characterize neural circuit transcriptional programs by identifying cell-type-specific gene signatures in defined brain regions.
- Profile inflammatory cytokine landscapes through spatial transcriptomic immune profiling in diseased or inflamed tissues.
- Correlate histopathology with molecular data by overlaying transcriptomic maps on H&E or immunofluorescence images for integrated histology and gene expression analysis.
Spatial Transcriptomic Platforms
Signios Bio uses the 10x Genomics Xenium and Visium CytAssist spatial platforms for high-resolution spatial gene expression profiling of FFPE, fixed frozen or fresh-frozen tissue sections. CytAssist automates probe transfer and library preparation to ensure consistent capture performance and robust gene detection.
