Break through the barriers that once hindered spatial analysis of gene expression in formalin-fixed paraffin-embedded (FFPE) tissue sections and unveil the hidden insights within your samples with Visium Spatial Gene Expression for FFPE. By merging the advantages of histological techniques with the vast throughput and investigative capabilities of RNA sequencing in FFPE tissue samples, Visium Spatial Gene Expression for FFPE enhances traditional pathologist-led analysis. Profile RNA expression across entire tissue sections with high resolution, encompassing more than 18,000 genes in human and mouse FFPE samples, to gain spatial insight into gene expression patterns.
Visium HD empowers a new era of spatial discovery, enhancing proven whole transcriptome spatial analysis with single cell–scale resolution, enabling continuous tissue coverage, and delivering best-in-class data with innovative probe-based chemistry and a Visium CytAssist-enabled workflow.

Figure 1. Spatial quantification of gene expression in bins
Space Ranger is used to count the UMI for each gene on every bin, obtaining a bin-gene expression matrix for the sample. After performing data QC, the figure below shows the distribution of UMI per gene across the spatial regions of the tissue.

Figure 3. t-SNE and UMAP dimensionality reduction of differentially expressed genes
The top 4 differentially expressed genes of each cluster are displayed in several ways. The figure presents the t-SNE and UMAP dimensional reduction visualization of differentially expressed genes.
