Spatial transcriptomics technologies have revolutionized our understanding of complex diseases by enabling researchers to map the cellular composition of tissues in a spatially resolved manner. This dataset roundup delves into two significant studies that utilize spatial transcriptomics to explore breast cancer and oral squamous cell carcinoma (OSCC), offering groundbreaking insights into their cellular ecosystems.

This dataset is crucial for advancing our understanding of breast cancer because it provides detailed single-cell and spatially resolved transcriptomics analysis. This comprehensive examination reveals the cellular heterogeneity within breast tumors, offering insights into the various cell types and their interactions, which can influence disease progression and treatment response. The study's immunophenotyping using CITE-seq uncovers immune cell profiles, including novel macrophage populations linked to clinical outcomes. By examining stromal-immune niches, the dataset enhances our knowledge of antitumor immune regulation and the spatial organization of different cell types in the tumor microenvironment. Additionally, it identifies nine distinct clusters (ecotypes) with unique cellular compositions and clinical outcomes, contributing valuable information for personalized treatment strategies. Overall, this transcriptional atlas of breast cancer cellular architecture is a foundational resource for understanding the complex ecosystem of the disease and informing future research and therapeutic approaches.

The dataset being presented in this study integrates Spatial Transcriptomics (ST) and Spatial Metabolomics (SM) techniques to provide a comprehensive and detailed landscape of oral squamous cell carcinoma (OSCC) tissues, specifically those derived from oral submucous fibrosis (OSF). By examining the transcriptomic and metabolomic profiles within OSCC tissues, the study reveals the complex interactions and progression patterns of the disease, from in situ carcinoma to partial epithelial-mesenchymal transition (pEMT), and ultimately, a cancer-associated fibroblast-like phenotype.
Through this integration, the dataset uncovers the intricate relationships between tumor cells, fibroblasts, and immune cells, as well as their impact on the tumor microenvironment.
One of the most significant findings of the dataset is the identification of major metabolic reprogramming in OSCC, particularly within the polyamine metabolism pathway. The abnormal expression of key enzymes involved in polyamine metabolism is shown to drive this metabolic reprogramming, which may subsequently reshape the tumor microenvironment and influence disease progression. This dataset is essential for advancing our understanding of OSCC and the complex molecular events underpinning its development, as well as for guiding the discovery of potential therapeutic targets and interventions.
Insights into OSCC
These datasets not only deepen our understanding of complex diseases like breast cancer and OSCC but also illustrate the power of spatial transcriptomics in uncovering novel insights that can drive therapeutic innovations. As we continue to unravel the spatial and molecular intricacies of diseases, we pave the way for more effective and personalised treatment strategies.
