Naproxen Induces Type X Collagen Expression in Human Bone Marrow Derived Mesenchymal Stem Cells through the Upregulation of 5-Lipoxygenase
Researchers determined the effect of naproxen on type X collagen protein expression and investigated the intracellular signaling pathways that mediate naproxen induced type X collagen gene expression in normal and osteoarthritis mesenchymal stem cells. [Tissue Eng Part A] Abstract

Regeneration of Uterine Horns in Rats Using Collagen Scaffolds Loaded with Human Embryonic Stem Cell-Derived Endometrium-Like Cells
Scientists aimed to efficiently generate endometrium-like cells from human embryonic stem cells and to use these cells with collagen scaffold to repair uterine damage. [Tissue Eng Part A] Abstract

Functional Nucleus Pulposus-Like Matrix Assembly by Human Mesenchymal Stromal Cells Is Directed by Macromer Concentration in Photocrosslinked Carboxymethylcellulose Hydrogels
Researchers evaluated the influence of carboxymethylcellulose macromer concentration on bulk hydrogel properties and nucleus pulposus-like matrix elaboration by human mesenchymal stromal cells. [Cell Tissue Res] Abstract

Low-Intensity Pulsed Ultrasound Activates Integrin-Mediated Mechanotransduction Pathway in Synovial Cells
Scientists examined the mechanotransduction pathway via the integrin/mitogen-activated protein kinase (MAPK) pathway in low-intensity pulsed ultrasound exposure on the synovial membrane cells. A possible integrin/MAPK pathway was examined by immunofluorescence and Western blotting analysis with antibodies targeting specific phosphorylation sites on intracellular signaling proteins. [Ann Biomed Eng] Abstract

Healing of a Xenogeneic Collagen Matrix for Keratinized Tissue Augmentation
Scientists evaluated histologically the healing of a xenogeneic collagen matrix used to augment the width of keratinized tissue around teeth. [Clin Oral Implants Res] Abstract

Viability of Chondrocytes Seeded onto a Collagen I/III Membrane for Matrix-Induced Autologous Chondrocyte Implantation
Researchers aimed to determine the effect of handling the membrane during matrix-induced autologous chondrocyte implantation surgery on the viability of implanted chondrocytes. [J Orthop Res] Abstract

Ureic Clearance Granule, Alleviates Renal Dysfunction and Tubulointerstitial Fibrosis by Promoting Extracellular Matrix Degradation in Renal Failure Rats, Compared with Enalapril
Researchers demonstrate the effects and mechanisms of uremic clearance granules on renal dysfunction and tubulointerstitial fibrosis by regulating extracellular matrix degradation and transforming growth factor-beta1/Smad signaling activity in vivo, compared with enalapril. [J Ethnopharmacol] Abstract

LRP4 Induces Extracellular Matrix Productions and Facilitates Chondrocyte Differentiation
Scientists found that lipoprotein receptor-related protein 4 (LRP4) induced gene expressions of extracellular matrix proteins of type II collagen, aggrecan, and type X collagen, as well as production of total proteoglycans in ATDC5 cells, whereas LRP4 knockdown had opposite effects. [Biochem Biophys Res Commun] Abstract

Soluble Biglycan as a Biomarker of Inflammatory Renal Diseases
Biglycan, generated by activated macrophages, can enter the circulation and its elevated levels in plasma and renal parenchyma correlate with unfavorable renal function and outcome. The authors focus on the critical role of soluble biglycan in inflammatory signaling in various renal disorders. [Int J Biochem Cell Biol] Abstract
