Spatial transcriptomics offers a revolutionary approach to understanding the tumor microenvironment (TME) in solid tumors by preserving the spatial context of gene expression, which is crucial for comprehending the interactions between various cell types, such as cancer cells, immune cells, fibroblasts, and endothelial cells. By integrating high-throughput sequencing and imaging technologies, spatial transcriptomics maps gene expression patterns within tissue sections, providing a high-resolution view of gene activity across the TME. This technique enables clinicians to study tumor heterogeneity, trace the lineage of cancer cells, and identify spatially resolved biomarkers essential for developing effective immunotherapies. By offering insights into tumor evolution, immune evasion, and therapeutic resistance, spatial transcriptomics holds great promise for improving the diagnosis, treatment, and prognosis of solid tumors, ultimately leading to better patient outcomes.
