What is Visium?

The Visium platform, developed by 10x Genomics, enables the profiling of the entire transcriptome of fresh and formalin fixed paraffin-embedded (FFPE) tissues. FFPE preservation can damage RNA, posing a challenge for transcriptomic research. However, Visium Spatial Gene Expression for FFPE overcomes this obstacle by providing high-resolution and sensitive spatial profiling of the entire transcriptome of human FFPE tissue sections. Moreover, Visium for FFPE is compatible with IF and allows for protein co-detection in addition to H&E staining.

The Visium Spatial Gene Expression method is utilized in genomics research to investigate the patterns of gene expression in tissues, taking into account their spatial information. The procedure involves using a slide-based platform to capture the spatial organization of RNA molecules within the tissue.

Initially, tissue sections are secured onto a slide and then treated to maintain the RNA molecules' original positions. Following this, barcoded oligonucleotides are introduced to the tissue sections, which attach to the RNA molecules and enable their identification during sequencing.

Once the tissue sections are ready, the RNA molecules undergo sequencing. The data obtained is then analyzed to ascertain the gene expression levels and their spatial distribution within the tissue. This knowledge can offer valuable insights into different biological processes, including tissue development, cellular interactions, and disease pathology.

How Does Visium Work?

How Does Visium Work? Spatial LifeStrands

The Visium Spatial Gene Expression for FFPE workflow measures RNA levels in intact, formalin-fixed paraffin-embedded (FFPE) tissue sections, using probes targeting the whole transcriptome.

Visium gene expression slide is covered with spatial spots which contains location information.

Spatial primers are attached to gene targeting probes in the elongation step. Thus, merging expression and spatial information

Those elongated sequences are read by next generation sequencing and map back to their original spots.

Initial H&E and IF stainings could be merged with spatial transcriptomics results using the Space Ranger-Data Visualization tool.

Space Ranger counts oligo ligation events to build the feature-barcode matrix.

As a consequence, if the probe is hybridized to a transcript with a variant, that variant will not be present in the sequencing data. The probe design avoids known SNPs.
