TOP STORY

The Generation of 3D Tissue Models Based on Hyaluronan Hydrogel-Coated Microcarriers within a Rotating Wall Vessel Bioreactor  ShareThis
Researchers designed a microcarrier bead coated with a synthetic extracellular matrix composed of a disulfide-crosslinked hyaluronan and gelatin hydrogel for 3D tissue engineering, that allows for enzyme-free cell detachment under mild reductive conditions (i.e. by a thiol-disulfide exchange reaction).

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Dissecting the Molecular Architecture of Integrin Adhesion Sites by Cryo-Electron Tomography
Findings clarify the internal architecture of focal adhesions at molecular resolution, and provide insights into their scaffolding and mechanosensory functions. [Nat Cell Biol]

Proangiogenic Scaffolds as Functional Templates for Cardiac Tissue Engineering
Researchers established a foundation for spatially controlled cardiac tissue engineering by providing discrete compartments for cardiomyocytes and stroma in a scaffold that enhances vascularization and integration while controlling the inflammatory response. [Proc Natl Acad Sci U S A]

Radially Aligned, Electrospun Nanofibers as Dural Substitutes for Wound Closure and Tissue Regeneration Applications
The paper reports the fabrication of scaffolds consisting of radially aligned poly(epsilon-caprolactone) nanofibers by utilizing a collector composed of a central point electrode and a peripheral ring electrode. [ACS Nano]

Mineralized Human Primary Osteoblast Matrices as a Model System to Analyze Interactions of Prostate Cancer Cells with the Bone Microenvironment
Researchers show that growth of prostate cancer cells on matrices produced by primary human osteoblasts mimics key features of prostate cancer bone metastases and thus is a suitable model system to study the tumor/bone micro-environment interaction in this disease. [Biomaterials]

Tocotrienols Have Potent Antifibrogenic Effects in Human Intestinal Fibroblasts
Tocotrienols exert multiple effects on human intestinal fibroblast, reducing cell proliferation, enhancing programmed cell death through apoptosis and autophagy, and decreasing extracellular matrix production. [Inflamm Bowel Dis]

Interleukin-18 Induces EMMPRIN Expression in Primary Cardiomyocytes via JNK/Sp1 Signaling, and MMP9 in Part via EMMPRIN, and Through AP-1 and NF-KappaB Activation
Results suggest that the elevated expression of IL-18 during myocardial injury and inflammation may favor extracellular matrix metalloproteinase inducer (EMMPRIN) and MMP induction, and extracellular matrix degradation. [Am J Physiol Heart Circ Physiol]

Cell-Derived Matrix Enhances Osteogenic Properties of Hydroxyapatite
In vitro-derived extracellular matrix mimics the native bone matrix, enhances the osteogenic properties of the hydroxyapatite microparticles, and might modulate the local inflammatory response in a bone repair-favorable way. [Tissue Eng Part A]

Guiding Epithelial Cell Phenotypes with Engineered Integrin Specific Recombinant Fibronectin Fragments
The studies demonstrate the importance of synergy in regulating epithelial cell phenotype relevant to tissue engineering as well as the utility of engineered integrin-specific extracellular matrix fragments in guiding cell phenotype. [Tissue Eng Part A]



INDUSTRY NEWS


NSF Funds Innovative Approach to Biomimetic Nanofiber Bone Regeneration
Funded by the National Science Foundation, Dr. Hongjun Wang, a professor in the Department of Chemistry, Chemical Biology and Biomedical Engineering at Stevens Institute of Technology and his collaborators have developed a revolutionary “bottom-up” approach for reconstructing intricate bone tissue with the potential to form hierarchical cortical bone. [Stevens Institute of Technology Press Release]

Tissue Regenix Secures CE Mark for dCELL® Vascular Patch
Tissue Regenix announced that it has received European CE Marking for its dCELL® Vascular Patch. [Tissue Regenix Group Press Release]

Panel Recommends Defining Select Agents by DNA Sequence
The way to bring synthetically designed genomes that could be potentially as deadly as known pathogens under regulation, according to a new National Academies report, is to develop a new system of defining select agents based on DNA sequences. [ScienceInsider]

Free Access to U.S. Research Papers Could Yield $1 Billion in Benefits
A new economic analysis finds that making taxpayer-funded scientific papers freely available would yield more than $1 billion in benefits to the U.S. economy over 30 years–five times the costs of archiving the papers. [ScienceInsider]
