50 Tumor–Myeloid Multicellular Programs Reveal ECM-Associated Macrophage Polarization in ccRCC
Abstract Background Clear cell renal cell carcinoma (ccRCC) is characterized by a highly heterogeneous tumor immune microenvironment. However, how tumor-intrinsic programs shape immune cell states remains incompletely understood. We aimed to identify multicellular programs (MCPs) linking tumor and immune compartments a...
