As one of the providers of spatial transcriptomic data analysis, CD Genomics uses bioinformatics to help you rapidly and accurately fully characterize tissue and structure at single-cell or subcellular resolution, providing a solid foundation for mechanistic understanding of many biological processes in health and disease. Our high-quality data analysis platform will be used to generate high-quality analysis results in a fast analysis cycle.
Human and animal tissues are composed of heterogeneous cell types that are organized and interact in a highly structured manner. However, bulk and single-cell sequencing technologies remove cells from their original microenvironment, resulting in a loss of spatial information. Spatial transcriptomics combines gene expression profiles with spatial information, allowing researchers to gain insight into the spatial organization and functional relationships of cells within tissues. This innovative approach has revolutionized our understanding of tissue structure, intercellular interactions, and the role of spatial organization in a variety of biological processes. There are various computational approaches to analyze spatial transcriptomic data for various purposes, as well as spatial multimodalomics and its potential for application in disease tissue.

Spatial transcriptome analysis has different applications in various fields of biological research. CD Genomics combines gene expression data with spatial context and aims to provide valuable insights into tissue development, disease pathology and therapeutic strategies.
Developmental biology: elucidating spatially specific gene expression patterns for tissue morphogenesis and cell fate determination. By analyzing gene expression at different developmental stages and spatial locations, researchers can identify the key regulators and signaling pathways involved in tissue patterns and organogenesis.
Tumor biology: characterize tumor heterogeneity, identify different tumor microenvironments, and explore tumor-immune cell interactions. This information can guide the development of targeted therapies and personalized treatment strategies.
Neuroscience: allow researchers to study gene expression within specific brain regions and cell types while retaining spatial information. By combining spatial with transcriptomics and other imaging techniques, researchers can map gene expression patterns to brain atlases, thereby facilitating the identification of cell types and their connectivity.
Plant biology: spatially regulated genes involved in processes such as growth, development and response to environmental stimuli can be identified. This information contributes to the understanding of plant organogenesis, cell differentiation and adaptation mechanisms.
