- 요약Innate immune cells constitute the majority of the tumor microenvironment (TME), where they mediate both natural anti-tumor immunity and immunotherapy responses. While single-cell Tand B-cell receptor sequencing has provided fundamental insights into the clonal dynamics of human adaptive immunity, the lack of analogous diverse sequences has precluded similar analysis of innate immune cells. Here, we developed a method leveraging somatic mitochondrial mutations to reconstruct clonal lineage relationships between single cells across donor-matched native human tissues. We jointly sequenced single-cell transposase-accessible chromatin and mitochondrial DNA (mtscATAC-seq) to profile 124,958 cells from matched tumor, non-involved lung tissue (NILT), and peripheral blood of early-stage non-small cell lung cancer (NSCLC) patients, as well as 93,757 cells from matched tumor and peripheral blood of ovarian cancer patients, enabling unbiased lineage and epigenetic analysis of thousands of immune cell clones across tissue sites and cancer types. By resolving clonal populations across innate immune subtypes, we demonstrated that TME-resident myeloid subsets, including macrophages and type 3 dendritic cells (DC3), are clonally linked to both circulating and tissue-infiltrating monocytes. Interestingly, we identified distinct DC-biased and macrophage-biased myeloid clones, enriched in the tumor and NILT, respectively, and found that their circulating monocyte precursors exhibit distinct epigenetic profiles, suggesting that myeloid differentiation fate may be predetermined before TME infiltration. These results delineate the clonal pathways of intratumoral myeloid cell recruitment and di!erentiation in human cancer and suggest that remodeling of the tumor myeloid compartment may be peripherally programmed.
