چکیده

Understanding the cell migration on micropatterned polymers, as well as their orientation is a critical issue in tissue engineering, since it is the preliminary step in the blood vessel formation. In this paper, we derive an agent-based model to describe the migration and the orientation of endothelial cells seeded on bioactive micropatterned polymers. The model is obtained thanks to the experimental observations, and it provides numerical results that are quantitatively in accordance with the experimental data.

Il s’agit en effet de la première étape pour la formation de vaisseaux sanguins. Dans cet article, nous avons établi un modèle d’agent décrivant la migration et l’orientation de cellules endothéliales dispersées sur des plaques composées de polymères bioactifs. Ce modèle est basé sur des considérations expérimentales et nous avons pu obtenir des résultats quantitativement en accord avec ces experiences.

Geometrical Microfeature Cues for Directing Tubulogenesis of Endothelial Cells

Angiogenesis, the formation of new blood vessels by sprouting from pre-existing ones, is critical for the establishment and maintenance of complex tissues. Angiogenesis is usually triggered by soluble growth factors such as VEGF. However, geometrical cues also play an important role in this process. Here we report the induction of angiogenesis solely by SVVYGLR peptide micropatterning on polyme...

Micropatterned structural control suppresses mechanotaxis of endothelial cells.

Vascular endothelial cell migration is critical in many physiological processes including wound healing and stent endothelialization. To determine how preexisting cell morphology influences cell migration under fluid shear stress, endothelial cells were preset in an elongated morphology on micropatterned substrates, and unidirectional shear stress was applied either parallel or perpendicular to...

Anti-angiogenic Effects of Metformin, an AMPK Activator, on Human Umbilical Vein Endothelial Cells and on Granulation Tissue in Rat

Objective(s)Metformin is well known for activation of AMP-activated protein kinase (AMPK). AMPK activation inhibits mammalian target of rapamycin (mTOR) as a key signaling process in cell proliferation. Recent epidemiological studies demonstrate that metformin lowers the risk for several types of cancer in diabetic patients. Concerning the critical role of angiogenesis in the incidence and prog...

تمایز سلول‌های دندریتیک مشتق از مونوسیت بر روی لایه‌ای از سلول‌های اندوتلیال به‌عنوان لایه تغذیه‌کننده

Background: The innate and adaptive immune responses are dependent on the migration of leukocytes across endothelial cells. Dendritic cells (DCs) play an important role in the initiation of cellular immune responses during their migration from tissues into the lymph nodes where they interact with endothelial cells of lymphatic vessels. We investigated the effect...

O 7: KCNK2 Regulates the Nanoscale Formation of Immune Docking Structures on Brain Endothelial Cells Under Autoinflammatory Conditions

KCNK2 was previously shown to regulate immune-cell trafficking into the central nervous system (CNS). Kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the CNS. An upregulation of the cellular adhesion molecules ICAM1 and VCAM1 on brain endothelial cells in K...
