Unlocking the Power of Spatial Transcriptomics and Single-Nuclei RNA Sequencing with S2 Genomics’ Singulator Platform
Spatial transcriptomics and single-nuclei RNA sequencing (snRNA-seq) have emerged as powerful tools for understanding the complex landscape of cellular heterogeneity and interactions within tissues. These technologies provide unprecedented insights into the spatial organization of gene expression, revealing how different cell types communicate and function within their microenvironment. However, traditional single-cell RNA-seq (scRNA-seq) methods often face limitations, such as bias towards overrepresenting immune cell types, hindering a comprehensive understanding of tissue complexity.
Overcoming Challenges in Tissue Dissociation
One of the major challenges in single-cell and single-nuclei genomics is the tissue dissociation process itself. Manual dissociation methods can be time-consuming, technically demanding, and prone to introducing biases in cell type representation. Additionally, these methods may trigger stress responses in cells, altering their gene expression profiles and confounding downstream analyses. To address these challenges, researchers need standardized and reproducible methods that ensure unbiased and efficient tissue dissociation.

S2 Genomics’ Singulator platform offers a cutting-edge solution for automated tissue dissociation and single-cell/nuclei isolation. By automating the dissociation process, the Singulator platform minimizes the risk of cell type bias and stress responses, ensuring the generation of high-quality, representative single-cell and single-nuclei suspensions. The platform’s compatibility with various downstream applications, including snRNA-seq and spatial transcriptomics, makes it a versatile tool for diverse research needs.
Case Study: Unraveling the Tumor Microenvironment with the Singulator Platform
In a recent study published in Nature Biotechnology, Haviv et al. (2024) utilized the Singulator platform to investigate the complex cellular landscape of the tumor microenvironment. By combining snRNA-seq data generated from tissues processed by the Singulator platform with spatial transcriptomics, the researchers were able to identify distinct immune cell populations within the tumor and their spatial localization (Figure 1b). This research demonstrates the power of integrating snRNA-seq with spatial transcriptomics to uncover the nuances of cellular interactions in complex biological systems.
