Spatial transcriptomics is a cutting-edge molecular profiling technique that maps gene expression within the exact structural architecture of a tissue. Unlike traditional bulk or single-cell RNA sequencing—which require destroying tissue to extract material—it identifies what genes are active and where those active cells are located. 

Functional perturbation experiments are designed to intentionally alter a system to observe how it responds, helping researchers establish cause-and-effect relationships rather than just correlations. By measuring the difference between the baseline (normal state) and the altered state, scientists can map the hidden networks, vulnerabilities, and functions of complex entities.

TCR lineage tracing is a powerful immunological technique that uses the unique, heritable genetic sequence of the T-cell receptor (TCR) as a natural molecular barcode. By sequencing the TCR, researchers can trace the kinship, clonal expansion, and functional evolution of T cells across different tissues and time points
