As life sciences enter the era of precision biology, spatial genomics and transcriptomics are transforming our ability to decode gene expression not just at the molecular level, but also within the physical context of cells and tissues. Unlike traditional genomics, which often loses spatial data through tissue homogenization, spatial biology technologies preserve the architectural layout of tissues, unlocking new insights in oncology, neuroscience, and developmental biology.
Spatial genomics and transcriptomics is typically segmented into three major workflows, spatial imaging, spatial sequencing, and spatial analysis; each playing a distinct role in enabling this next generation understanding of cellular biology. Across Asia, Europe, and the U.S., major biotech firms and research institutions are actively building solutions across these verticals to drive scientific and clinical progress.

Illustration 1: Spatial Genomics and Transcriptomics Market Overview
Spatial imaging technologies form the visual foundation of spatial genomics by pinpointing where specific RNAs, proteins, or other molecules reside within complex tissues. Laser Capture Microdissection (LCM) pioneered this precision, enabling targeted sampling of cells for downstream analysis. Organizations like Thermo Fisher Scientific and Leica Microsystems offer sophisticated LCM platforms tailored for spatial research. Immunohistochemistry (IHC) and Fluorescent In-Situ Hybridization (FISH) remain powerful tools for visualizing protein and gene expression in situ, with companies such as Agilent Technologies and Bio-Techne advancing multiplexed staining and detection methods. High-resolution microscopy, now enhanced by companies like Zeiss and Olympus, enables deep imaging of tissue structures, while spatial barcoding technologies, like those from 10x Genomics, allow researchers to tag thousands of RNA molecules within a defined spatial framework. Together, these imaging tools establish the groundwork for spatially resolved molecular atlases.
Where imaging leaves off, spatial sequencing steps in, capturing high-dimensional transcriptomic data linked directly to tissue location. Next-Generation Sequencing (NGS) platforms, when combined with spatial barcoding, have enabled true tissue-wide spatial transcriptomics; here, 10x Genomics Visium platform is a market leader, making it possible to map whole transcriptomes at cellular resolution. Fluorescent In-Situ Sequencing (FISSEQ), developed through partnerships like those at Harvard’s Wyss Institute, integrates direct RNA sequencing within tissue sections, merging microscopy and sequencing into a single workflow. Emerging methods such as in-vivo transcription capture and microtomy-based sequencing are also gaining ground, with startups like Cartana (acquired by 10x Genomics) and institutions like Broad Institute pushing innovations that reduce the complexity and increase the scalability of spatial sequencing. These technologies allow scientists to build spatial gene expression maps that are revolutionizing fields like tumor microenvironment profiling and brain tissue mapping.
The surge of spatial data generated through imaging and sequencing workflows has driven rapid innovation in computational biology. Advanced spatial analysis tools are essential for extracting meaningful patterns from high-dimensional datasets. Nanostring Technologies, with its GeoMx Digital Spatial Profiler, has integrated powerful data visualization capabilities that allow researchers to explore gene expression across entire tissue sections. Meanwhile, companies like Akoya Biosciences and bioinformatics groups such as Seurat Labs are leading the development of AI-powered clustering algorithms, spatial heatmaps, and 3D reconstruction software that enable researchers to interpret cell-to-cell communication, gene expression gradients, and spatial heterogeneity with unprecedented clarity. Spatial analysis has become crucial not just for basic research, but also for translational applications such as biomarker discovery, immune-oncology profiling, and digital pathology integration.
