loading . . . Mapping heterogeneity in the tumor microenvironment of renal cell carcinoma through single-cell omics Renal cell carcinoma (RCC) outcomes are shaped by a complex tumor microenvironment (TME), where malignant cells represent only a minority of the tissue. Recent advances in single-cell technologies â including single-cell RNA sequencing, single-nucleus RNA sequencing, single-cell assay for transposase-accessible chromatin sequencing, single-cell T-cell receptor sequencing, and imaging mass cytometry â have uncovered the cellular, regulatory, and spatial heterogeneity of RCC. Here, we synthesize insights from these approaches to define diverse CD8+ T-cell subsets and exhaustion trajectories, as well as the origins, phenotypic diversity, and functional states of other immune cells including tumor-associated macrophages, dendritic cells, natural killer cells and cancer-associated fibroblasts. Together, these findings highlight the transformative potential of single-cell technologies to unravel TME complexity, identify biomarkers of therapeutic response, and guide precision immunotherapy in RCC. http://dlvr.it/TPc4Gj
