WebThe scaffold-free architecture accommodated close interactions between cancer epithelial cells and stromal fibroblasts and the self-assembly of HUVECs into capillary-like networks. The authors further assessed the efficacy of well-established chemotherapeutics using the 3D printed model, including the VEGF inhibitor sunitinib. WebOct 26, 2024 · Third, perivascular fibroblasts are much more abundant than pericytes, and are associated with both arterial and venous ISVs in similar numbers unlike pericytes. Finally, perivascular fibroblasts are positioned abluminal to pericytes and appear more globular with numerous shorter processes that extend around the endothelium.
WebThe capillary lumen is lined by a single layer of endo-thelial cells. Separated by the basement membrane, capillary EC are covered by pericytes that stretch out with long dendrite-like processes to physically contact EC. The image summarizes the most established markers of pericytes, some of the key regulators of pericyte function, the

WebSep 20, 2016 · Vascular pericytes, an important cellular component in the tumor microenvironment, are often associated with tumor vasculatures, and their functions in cancer invasion and metastasis are poorly understood. Here we show that PDGF-BB induces pericyte-fibroblast transition (PFT), which significantly contributes to tumor invasion and …
Pericytes (formerly called Rouget cells) are multi-functional mural cells of the microcirculation that wrap around the endothelial cells that line the capillaries throughout the body. Pericytes are embedded in the basement membrane of blood capillaries, where they communicate with endothelial cells by means of both direct physical contact and paracrine signaling. The morphology, distributi…
