Injectable and Thermo-Sensitive PEG-PCL-PEG Copolymer/Collagen/n-HA Hydrogel Composite for Guided Bone Regeneration
A novel three-component biomimetic hydrogel composite was successfully prepared in this study, which was composed of triblock PEG-PCL-PEG copolymer, collagen and nano-hydroxyapatite (n-HA). [Biomaterials] Abstract

Estradiol Protects the Dermal Hyaluronan/Versican Matrix during Photoaging by Release of Epidermal Growth Factor from Keratinocytes
Researchers aimed to explore the molecular mechanisms mediating the effects of estrogen on hyaluronan-rich extracellular matrix during photoaging. [J Biol Chem] Abstract

O-Linked LacdiNAc-Modified Glycans in Extracellular Matrix Glycoproteins Are Specifically Phosphorylated at the Subterminal GlcNAc
In searching for mammalian proteins modified with O-linked LacdiNAc, researchers identified six positive species among nine endogenous and recombinant O-glycoproteins, which were extracellular matrix, or matrix-related proteins. [J Biol Chem] Abstract

Effects of Cryopreservation, Decellularization and Novel ECM Conditioning on the Quasi-Static and Time-Dependent Properties of the Pulmonary Valve Leaflet
The stress-strain, relaxation and creep behavior of the ovine pulmonary valve leaflet was investigated under planar-biaxial loading conditions to determine the effects of decellularization and a novel post-decellularization extracellular matrix (ECM) conditioning process. [Acta Biomater] Abstract

Granzyme B Cleaves Decorin, Biglycan and Soluble Betaglycan, Releasing Active Transforming Growth Factor-β1
Researchers’ objective was to identify proteoglycan (PG) substrates of granzyme B (GrB) and examine the ability of GrB to release PG-sequestered transforming growth factor-β1 into the extracellular milieu. [PLoS One] Abstract

Increased Fibrosis and Interstitial Fluid Pressure in Two Different Types of Syngeneic Murine Carcinoma Grown in Integrin β3-Subunit Deficient Mice
Scientists show that αVβ3 expressed by stromal cells is involved in the control of interstitial fluid pressure, extracellular volume and collagen scaffold architecture in experimental murine carcinoma. [PLoS One] Abstract

Survival of Cord Blood Hematopoietic Stem Cells in a Hyaluronan Hydrogel for Ex Vivo Biomimicry
A hyaluronic acid scaffold has been used for the first time to maintain long-term cultures of CD34⁺ hematopoietic cells obtained from human cord blood. [J Tissue Eng Regen Med] Abstract

Integrin-Mediated Adhesion of Human Mesenchymal Stem Cells to Extracellular Matrix Proteins Adsorbed to Polymer Surfaces
Researchers have investigated the ability of human bone marrow derived stem cells to adhere to extracellular matrix proteins, including fibronectin and vitronectin which are present in plasma and serum. [Biomed Mater] Abstract

American CryoStem, PGen to Develop Stem Cells for Wound Healing
American CryoStem and Protein Genomics (PGen) have agreed to work together to develop cellular therapies for the wound healing and other regenerative markets. [Genetic Engineering & Biotechnology News]
