In Vitro Microvessels for the Study of Angiogenesis and Thrombosis
Scientists engineered living microvascular networks in three-dimensional tissue scaffolds and demonstrated their biofunctionality in vitro. [Proc Natl Acad Sci USA] Abstract | Press Release

High-Throughput Cellular Screening of Engineered Extracellular Matrix Based on Combinatorial Polyelectrolyte Multilayer Films
Researchers developed a combinatorial method to generate coatings that self assemble from solutions of polyelectrolytes in water, layer by layer, to produce a polyelectrolyte multilayer coating that has enabled high-throughput screening for cellular biocompatibility. [Biomaterials] Abstract

Confluence Switch Signaling Regulates ECM Composition and Plasmin Proteolytic Cascade in Keratinocytes
Scientists demonstrated that confluence dependent-signaling orchestrates not only growth-inhibition and differentiation but also controls extracellular matrix (ECM)-proteolysis and basement membrane formation. [J Cell Sci] Abstract

Oriented Lamellar Silk Fibrous Scaffolds to Drive Cartilage Matrix Orientation: Towards Annulus Fibrosus Tissue Engineering
By offering the combined effect of cell/matrix alignment and chondrogenic support, the developed silk fibroin scaffolds with precise fiber orientation in lamellar form represent a suitable substrate for tissue engineering of the annulus fibrosus part of intervertebral disc. [Acta Biomater] Abstract

Proteomic Analysis of α4β1 Integrin Adhesion Complexes Reveals α-Subunit-Dependent Protein Recruitment
Researchers report the isolation of ligand-induced adhesion complexes associated with wild-type α4β1 integrin, an activated α4β1 variant in the absence of the α cytoplasmic domain and a chimeric α4β1 variant with α5 leg and cytoplasmic domains, and the cataloguing of their proteomes by MS. [Proteomics] Abstract

Prostaglandins but Not Leukotrienes Alter Extracellular Matrix Protein Deposition and Cytokine Release in Primary Human Airway Smooth Muscle Cells and Fibroblasts
Increasing evidence suggests that eicosanoids may directly mediate remodeling. Researchers assessed whether these substances could alter extracellular matrix proteins and the inflammatory profiles of primary human airway smooth muscle cells and fibroblasts. [Am J Physiol Lung Cell Mol Physiol] Abstract

Beta3 Integrin Modulates Transforming Growth Factor Beta Induced (TGFBI) Function and Paclitaxel Response in Ovarian Cancer Cells 
Scientists suggest that different extracellular matrix components use distinct signaling mechanisms in ovarian cancer cells and in particular, that TGFBI preferentially interacts through a beta3 integrin receptor mediated mechanism to regulate the response of cells to paclitaxel-induced cell death.

Extracellular Matrix Constituents Interfere with Newcastle Disease Virus Spread in a Solid Tissue and Diminishes Its Potential Oncolytic Activity
The results of this study indicate that the extracellular matrix acts as a barrier to virus spreading within solid tumor tissues and that this restriction must be overcome to achieve effective oncolysis with Newcastle disease virus. [J Gen Virol] Abstract

Comparison of Decellularization Techniques for Preparation of Extracellular Matrix Scaffolds Derived from Three-Dimensional Cell Culture
Scientists developed a method to prepare cultured cell-derived extracellular matrix scaffolds by combining three-dimensional cell culture, decellularization, and selective template removal. [J Biomed Mater Res A] Abstract
