This research aims to understand the role of tumor cell fusion with lipid-associated macrophages in breast cancer metastasis.
Utilized single-cell transcriptomic analysis to study tumor heterogeneity.
Profiled primary tumors, metastases, and circulating tumor cells from multiple breast cancer patients.
Correlated the presence of tumor-LAM fusion cells with metastatic progression.
Identified a unique EPCAM+ CD68+ TREM2+ tumor subpopulation resulting from fusion of tumor cells with macrophages.
Demonstrated enhanced proliferation and metastasis formation in vitro and in vivo with stable fusion clonal lines.
Revealed involvement of SNX10, ANO6, and CBX3 in mediating tumor–LAM fusion and promoting cancer progression.
