Human organ chip models recapitulate FRC-driven high endothelial venule differentiation, immune recruitment, and cancer-induced disruption.
High endothelial venules (HEVs) are specialized post-capillary venules that gate lymphocyte entry into lymph nodes, yet human in vitro models that capture their specialization remain limited. Here, we develop a perfusable human HEV-on-chip in which blood endothelial cells (BECs) form an engineered microvessel within a...
