TOP STORY
Scientists Uncover Navigation System Used by Cancer, Nerve Cells
Researchers have found a ”roving detection system” on the surface of cells that may point to new ways of treating diseases like cancer, Parkinson’s disease and amyotrophic lateral sclerosis (ALS). [Press release from Duke University discussing online prepublication in the Journal of Cell Biology] Press Release | Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
An Extracellular-Matrix-Specific GEF-GAP Interaction Regulates Rho GTPase Crosstalk for 3D Collagen Migration
Researchers searched for mechanisms selectively regulating three-dimensional (3D) cell migration in different matrix environments and discovered a form of ​Cdc42-​RhoA crosstalk governing cell migration through a specific pair of GTPase activator and inhibitor molecules. [Nat Cell Biol] Abstract

Molecular Mobility of Scaffolds’ Biopolymers Influences Cell Growth
Scientists investigated the correlation of fibroblast cell growth on different gelatin scaffolds with their morphological, mechanical as well as surface molecular properties. [ACS Appl Mater Interfaces] Abstract

Investigating the Spatial Distribution of Integrin β1 in Patterned Human Mesenchymal Stem Cells Using Super-Resolution Imaging
Researchers report the distinct recruitment of active integrin beta 1 in human mesenchymal stem cells when they were committed towards the cardiomyogenic lineage on micropatterned surface. [ACS Appl Mater Interfaces] Abstract

Adiponectin Modulates Focal Adhesion Disassembly in Activated Hepatic Stellate Cells: Implication for Reversing Hepatic Fibrosis
Scientists postulate a novel molecular mechanism, whereby adiponectin targets focal adhesion kinase activity and disrupts key features of the fibrogenic response. [FASEB J] Abstract

A Chromatin Modifier Regulates Sertoli Cell Response to Mono-(2-Ethylhexyl) Phthalate (MEHP) via Tissue Inhibitor of Metalloproteinase 2 (TIMP2) Signaling
Researchers report the potential signaling events related to up-regulation of metastasis associated protein 1, a master chromatin modifier, during MEHP-induced Sertoli cells injury. [Biochim Biophys Acta] Abstract

miR-130b Suppresses Prostate Cancer Metastasis through Down-Regulation of MMP2
Using a mouse model, researchers reveal that miR-130b-expressed prostate cancer cells displayed significant reduction in tumor metastasis. Furthermore, they identified and validated matrix metalloproteinase-2 (MMP2) as a direct target of miR-130b. [Mol Carcinog] Abstract

Matrix Metalloproteinase-2 Is Downregulated in Sciatic Nerve by Streptozotocin Induced Diabetes and/or Treatment with Minocycline: Implications for Nerve Regeneration
Scientists show that matrix metalloproteinase-2 (MMP-2) is expressed constitutively in the sciatic nerve in vivo and treatment with minocycline or diabetes leads to downregulation of MMP-2 expression and activity. [Exp Neurol] Abstract

JNK and Akt Signaling Pathways Regulating TNF-α-Induced IL-32 Expression in Human Lung Fibroblasts: Implications in Airway Inflammation
Scientists examined the expression of IL-32 by TNF-α in primary human lung fibroblasts. Human lung fibroblasts were cultured in the presence or absence of TNF-α and/or other cytokines/TLR ligands or various signaling molecule inhibitors to analyze the expression of IL-32 by quantitative RT-PCR and enzyme-linked immunosorbent assay. [Immunology] Abstract

Immunogenicity of Intensively Decellularized Equine Carotid Arteries Is Conferred by the Extracellular Matrix Protein Collagen Type VI
Researchers demonstrate the residual immunogenicity of an extensively decellularized equine carotid artery and identify the involved immunogenic components. [PLoS One] Full Article

Dual-Functioning Phage-Derived Peptides Encourage Human Bone Marrow Cell-Specific Attachment to Mineralized Biomaterials
Researchers aimed to measure apatite binding affinity, human bone marrow stromal cell (hBMSC) adhesion strength, and peptide specificity to hBMSCs when the apatite and cell-specific peptides are combined into a dual-functioning peptide. [Connect Tissue Res] Abstract

Free Cell Stem Cell Poster: Directed Differentiation of ESCs/iPSCs
 
REVIEWS
Bone Tissue Remodeling and Development: Focus on Matrix Metalloproteinase Functions
The authors look at the principal properties of matrix metalloproteinases and their inhibitors, provide an update on their known functions in bone development and remodeling and discuss their potential application to bone bioengineering. [Arch Biochem Biophys] Abstract

Sulfated Sugars in the Extracellular Matrix Orchestrate Ovarian Cancer Development ‘When Sweet Turns Sour’
The authors focus on the various functions of chondroitin sulfate in tumor growth, angiogenesis, dissemination and immunosilencing of ovarian cancer. [Gynecol Oncol] Abstract
