Why study the TME with NGS?
The tumor microenvironment (TME) is a complex network of cells, molecules and blood vessels that shapes tumor growth, progression and response to therapy. A key part of this system is the tumor immune microenvironment (TIME), where interactions between tumor cells and immune cells can influence immune activation, suppression and tumor immune evasion. This makes immune cell profiling, including analysis of tumor-infiltrating lymphocytes (TILs), especially important in immuno-oncology research.
Intratumoral heterogeneity within the TME remains a major challenge in tumor profiling and understanding cancer biology. Because the TME is highly dynamic and heterogeneous, its analysis requires sensitive technologies that can resolve its diverse cellular and molecular components. Next-generation sequencing (NGS) provides the depth and resolution needed to capture genomic and transcriptomic complexity and uncover the molecular interactions shaping the TME.
RNA sequencing approaches for TME analysis
RNA-seq provides powerful insights into the cellular and molecular complexity of the TME. By profiling gene expression, researchers can investigate interactions between tumor, immune and stromal cells, identify biomarkers associated with disease progression or treatment response, and gain a deeper understanding of the biological processes that shape the TME.
Depending on the research question, bulk RNA-seq enables tissue-wide transcriptome profiling across large sample cohorts, while single-cell RNA-seq resolves the cellular diversity and functional states that underlie these tissue-level signals. Together, these complementary approaches provide a comprehensive view of the TME across multiple levels of biological resolution.

QIAseq FastSelect has really been phenomenal with the RNA sequencing in my project. The RNA was degraded and almost unusable, but QIAseq FastSelect really removes the ribosomal RNA in these degraded samples and has improved our sequencing libraries.

TCR profiling in the TME
T cell receptor (TCR) profiling reveals how T cells recognize and respond to tumors. Researchers can characterize immune repertoires across cohorts with bulk TCR sequencing or combine TCR profiling with single-cell sequencing to link individual clonotypes to gene expression and functional states.
When combined with bulk or single-cell RNA-seq, TCR profiling provides a more comprehensive view of the tumor microenvironment by integrating immune repertoire information with transcriptomic data. This integrated approach helps researchers investigate immune repertoire diversity, monitor clonal expansion, identify biomarkers of immunotherapy response and gain deeper insights into the mechanisms underlying anti-tumor immunity, treatment resistance and immune-oncology research.
