| PUBLICATIONS (Ranked by impact factor of the journal) | Rotational Motion during Three-Dimensional Morphogenesis of Mammary Epithelial Acini Relates to Laminin Matrix Assembly Investigators performed multidimensional live-cell imaging analysis to track the morphogenetic process starting from a single cell to the development of a multicellular, spherical structure composed of polarized epithelial cells surrounding a hollow lumen. [Proc Natl Acad Sci USA] Abstract Structural Integrity, Extracellular Matrix Components and Immunogenicity of Decellularized Laryngeal Scaffold with Preserved Cartilage Scientists constructed a decellularized, whole, laryngeal scaffold with preserved chondrocytes using perfusion techniques and evaluated the immunogenicity of the decellularized scaffold in vitro and in vivo in a rat model. [Biomaterials] Abstract Engineering an In Situ Crosslinkable Hydrogel for Enhanced Remyelination The authors aimed to engineer an injectable biocompatible hydrogel system as a supportive niche to provide a regeneration permissive microenvironment for transplanted oligodendrocyte progenitor cells to survive, functionally differentiate, and remyelinate central nervous system lesions. [FASEB J] Abstract Azithromycin Increases In Vitro Fibronectin Production through Interactions between Macrophages and Fibroblasts Stimulated with Pseudomonas aeruginosa Researchers have previously demonstrated that azithromycin polarizes macrophages towards an alternatively activated phenotype, thereby blunting inflammation associated with infection. Because this phenotype is pro-fibrotic, it’s important to evaluate azithromycin’s consequential effects upon fibroblast function and extracellular matrix protein production. [J Antimicrob Chemother] Abstract Elastin, A Novel Extracellular Matrix Protein Adhering to Mycobacterial Antigen 85 Complex Investigators report that the extracellular matrix components, elastin and its precursor derived from human aorta, lung, and skin, serve as binding partners of Ag85 from mycobacterium tuberculosis. [J Biol Chem] Abstract | Full Article Bioactive Polyacrylamide Hydrogels with Gradients in Mechanical Stiffness Researchers proposed a novel, single step method for the production of polyacrylamide hydrogels with a gradient in mechanical properties. [Biotechnol Bioeng] Abstract Curcumin Targets Fibroblast-Tumor Cell Interactions in Oral Squamous Cell Carcinoma Co-culture of periodontal ligament fibroblasts (PDLs) and SCC-25 oral squamous carcinoma cells (OSCC) results in conversion of PDLs into carcinoma-associated fibroblasts (CAFs) and induces epithelial-to mesenchymal transition of OSCC tumor cells. Investigators hypothesized that Curcumin targets this dynamic mutual interaction between CAFs and tumor cells. [Exp Cell Res] Abstract Fibroblast Growth on Micro- and Nanopatterned Surfaces Prepared by a Novel Sol-Gel Phase Separation Method To test the effect of varying the supporting surface structure on cell growth, investigators applied a novel sol-gel phase separation-based method to prepare micro- and nanopatterned surfaces with round surface structure features. Growth characteristics and morphology of primary human dermal fibroblasts were found to be significantly modulated by the microstructure of the substrate. [J Mater Sci Mater Med] Abstract Chondrocyte-Alginate Constructs with or without TGF-β1 Produces Superior Extracellular Matrix Expression than Monolayer Cultures A study using chondrocytes isolated from rabbit knee articular cartilage expanded in vitro as monolayer and chondrocyte-alginate constructs was conducted. Immunohistochemical evaluation and extracellular matrix distribution was examined with or without transforming growth factor (TGF-β1) supplement to determine the ability of cells to express major chondrogenic proteins in these environments. [Mol Cell Biochem] Abstract Design of Bioactive Electrospun Scaffolds for Bone Tissue Engineering Scientists aimed to produce polycaprolactone (PCL) and PCL/gelatin fibrous scaffolds by electrospinning to engineer functional bone by the careful reproduction of the native microenvironment of the natural tissue.

| SCIENCE NEWS | To Revert Breast Cancer Cells, Give Them the Squeeze While the traditional view of cancer development focuses on the genetic mutations within the cell, researchers conducted pioneering experiments that showed that a malignant cell is not doomed to become a tumor, but that its fate is dependent on its interaction with the surrounding microenvironment.

| INDUSTRY NEWS | Organovo Partners with Autodesk Research to Develop 3D Bioprinting Software Organovo Holdings, Inc., a creator and manufacturer of functional, three-dimensional (3D) human tissues for medical research and therapeutic applications, is working together with researchers at Autodesk, Inc. to create the first 3D design software for bioprinting. The software will represent a major step forward in usability and functionality for designing three-dimensional human tissues, and has the potential to open up bioprinting to a broader group of users. [Organovo Holdings, Inc.] Press Release New Facility Will Bridge Research and Stem Cell Therapies The University of Rochester Medical Center has opened the doors on a new facility that will enable researchers to create, study, and ultimately use stem cells and their offspring in early-phase experimental human therapies. The Upstate Stem Cell cGMP Facility was created with $3.5 million in support from the Empire State Stem Cell Board. [University of Rochester Medical Center] Press Release |
