when grown in monolayer culture at low density and with the addition of serum, cartilage cells dedifferentiate or are overgrown by fibroblast-like cells. the aim of this study was to optimize the cultivation of chondrocytes in monolayer culture and to slow down their transformation or their overgrowth by fibroblast-like cells. the interaction between chondrocytes and cartilage-specifc matrix is...

Platelet adhesion and activation are mediated by integrin αIIbβ3 clustering, which is crucial for the hemostatic function of platelets. In an activated state, integrins provide connection between extracellular matrix actin cytoskeleton through a variety cytoplasmic proteins, such as talin. Here, droplet-based microfluidics applied to generate cell-sized giant unilamellar vesicles (GUVs) with de...

The hallmarks of leukocyte adhesion deficiency (LAD) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. These molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. Over las...

It is well known that Arginine-Glycine-Aspartic acid (RGD) and Asparagine-Glycine-Arginine (NGR) peptides preferentially bind to integrin receptors and aminopeptidase Nrespectively and these two receptors play important roles in angiogenesis. Therefore ketoprofenas a non-selective cox Inhibitor was conjugated with linear RGD and NGR to take advantageof targeting capability of these two motifs a...

Fibronectin coating increases implant biocompatibility by enhancing surface endothelializationviaintegrin-mediated binding.

ABSTRACT Integrin-mediated cell–extracellular matrix (ECM) interactions play crucial roles in a broad range of physiological and pathological processes. Kindlins are important positive regulators integrin activation. The FERM-domain-containing kindlin family comprises three members, kindlin-1, kindlin-2 kindlin-3 (also known as FERMT1, FERMT2 FERMT3), which share high sequence similarity (ident...

Abstract Rapid migration of mesenchymal stem cells (MSCs) on device surfaces could support in vivo tissue integration and might facilitate vitro organoid formation. Here, polydopamine (PDA) is explored as a biofunctional coating to effectively promote MSC motility. It hypothesized that PDA stimulates fibronectin deposition this way enhances integrin-mediated capability. The random directional c...

While much work has been done in the design of biomaterials to control integrin-mediated adhesion, less emphasis put on functionalization materials with cadherin ligands. Yet, cell–cell contacts combination cell–matrix interactions are key driving embryonic development, collective cell migration, epithelial mesenchymal transition, and cancer metastatic processes, among others. This review focus...
