VCAM1 and nonpapillary renal cell carcinoma: The cell-adhesion molecule VCAM1 has reported expression on a subset of pancreatic TECs [43], though in our dataset, it was localized to the same transitional subpopulation of ECs that expressed ACKR1. These UMAP findings confirmed the results of the DEG analysis but also identified differences from previous studies, which could be due to the increased resolution of our enriched EC dataset and ccRCC-specific patterns.
