SCIENCE NEWS

Scientists Develop New Way to Grow Adult Stem Cells in Culture
Researchers have found that growing muscle stem cells on a specially developed synthetic matrix that mimics the elasticity of real muscle allows them to maintain their self-renewing properties. [Press release from the Stanford University School of Medicine discussing online prepublication in Science]

Engineering Could Give Reconstructive Surgery a Face-Lift
Researchers applied an engineering design technique called topology optimization. The approach uses extensive 3D modeling to design structures that need to support specific loads in a confined space. [Press release from the University of Illinois discussing online prepublication in the Proceedings of the National Academy of Science USA]

A New Generation of Biological Scaffolds
Researchers have been working on ways of producing biological scaffolds, derived from natural human or animal tissues that will not be rejected by a patient’s immune system and can be repaired and renewed like normal tissue. The technique developed by the Leeds group removes the cells from natural tissues to leave a biological scaffold which can be regenerated by the patient’s own cells.

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Substrate Elasticity Regulates Skeletal Muscle Stem Cell Self-Renewal in Culture
Unlike muscle stem cells (MuSCs) on rigid plastic dishes, MuSCs cultured on soft hydrogel substrates that mimic the elasticity of muscle self-renew in vitro and contribute extensively to muscle regeneration when subsequently transplanted into mice and assayed histologically and quantitatively by noninvasive bioluminescence imaging. [Science]

The Extracellular Matrix Molecule Hyaluronic Acid Regulates Hippocampal Synaptic Plasticity by Modulating Postsynaptic L-Type Ca2+ Channels
Observations unveil a previously unrecognized mechanism by which the perisynaptic extracellular matrix influences use-dependent synaptic plasticity through regulation of dendritic Ca2+ channels. [Neuron]

Topological Optimization for Designing Patient-Specific Large Craniofacial Segmental Bone Replacements
Topological optimization for designing facial bone tissue replacements might improve current clinical methods and provide essential enabling technology to translate generic bone tissue engineering methods into specific solutions for individual patients. [Proc Natl Acad Sci U S A]

Modular Enzymatically Crosslinked Protein Polymer Hydrogels for In Situ Gelation
Biomaterials that mimic the extracellular matrix in both modularity and crosslinking chemistry have the potential to recapitulate the instructive signals that ultimately control cell fate. Toward this goal, modular protein polymer-based hydrogels were created through genetic engineering and enzymatic crosslinking. [Biomaterials]

Preserved Extracellular Matrix Components and Retained Biological Activity in Decellularized Porcine Mesothelium
Decellularized mesothelium is a sheet material with a combination of strength and biological activity that may have many potential applications in surgical repair and regenerative medicine. [Biomaterials]

Extracellular Matrix of Glioblastoma Inhibits Polarization and Transmigration of T Cells: The Role of Tenascin-C in Immune Suppression
Researchers demonstrate in this study that the extracellular matrix produced by tumors can directly regulate T cell migration. [J Immunol]

Combinatorial Extracellular Matrices for Human Embryonic Stem Cell Differentiation in 3D
Researchers investigated the effects of combinatorial extracellular matrix (ECM) proteins on controlled human embryonic stem cell differentiation. Varying ECM compositions in 3D markedly affects cell behavior, and optimal compositions of ECM hydrogels are identified that facilitate specific-lineage differentiation of stem cells. [Biomacromolecules]

Lack of Collagen XVIII/Endostatin Exacerbates Immune-Mediated Glomerulonephritis
Results suggest that collagen XVIII/endostatin preserves the integrity of the extracellular matrix and capillaries in the kidney, protecting against progressive glomerulonephritis. [J Am Soc Nephrol]

Collagen/Heparin Coating on Titanium Surface Improves the Biocompatibility of Titanium Applied as a Blood-Contacting Biomaterial
This article deals with improving the endothelial progenitor cell compatibility and hemocompatibility of titanium by coating an extracellular matrix-like film with heparin and collagen by a layer-by-layer self-assembly technique. [J Biomed Mater Res A]

A Novel Composite Construct Increases the Vascularization Potential of PEG Hydrogels Through the Incorporation of Large Fibrin Ribbons
Distribution of large fibrin ribbons throughout poly(ethylene glycol) (PEG) hydrogels provide a potential mechanism for vascularization of a well-established biomaterial without inherently changing its desirable properties. [J Biomed Mater Res A]

Fibronectin and Laminin Promote Differentiation of Human Mesenchymal Stem Cells Into Insulin Producing Cells Through Activating Akt and ERK
Researchers report adding extracellular matrix proteins such as fibronectin or laminin enhances pancreatic differentiation with increases in insulin and Glut2 gene expressions, proinsulin and insulin protein levels, and insulin release in response to elevated glucose concentration. [J Biomed Sci]
