TOP STORY
Bone Marrow Stromal Cells Create a Permissive Microenvironment for Myeloma Development: A New Stromal Role for Wnt Inhibitor Dkk1
Researchers’ results demonstrate novel roles of bone marrow stromal cells (BMSCs) and BMSC-derived Dkk1 in the pathogenesis of multiple myeloma in vivo. [Cancer Res] Abstract

PUBLICATIONS (Ranked by Impact Factor of the Journal)

Atmospheric Oxygen Inhibits Growth and Differentiation of Marrow-Derived Mouse Mesenchymal Stem Cells via a p53 Dependent Mechanism: Implications for Long-Term Culture Expansion
Herein, researchers demonstrate that exposure to atmospheric oxygen rapidly induced p53, TOP2A and BAX expression and mitochondrial reactive oxygen species generation in primary mouse mesenchymal stem cells resulting in oxidative stress, reduced cell viability and inhibition of cell proliferation. [Stem Cells] Abstract

Enhanced Apoptosis and Senescence of Bone Marrow-Derived Mesenchymal Stem Cells in Patients with Systemic Lupus Erythematosus
In this study, scientists aimed to investigate whether apoptosis and senescence of systemic lupus erythematosus bone marrow mesenchymal stem cells were dysregulated. [Stem Cells Dev] Abstract

Up-Regulation of miR-22 Promotes Osteogenic Differentiation and Inhibits Adipogenic Differentiation of Human Adipose Tissue-Derived Mesenchymal Stem Cells by Repressing HDAC6 Protein Expression
Here, microRNA-22 (miR-22) was found to regulate adipogenic and osteogenic differentiation of human adipose tissue-derived mesenchymal stem cells in opposite directions. [Stem Cells Dev] Abstract

Migration of Human Mesenchymal Stem Cells under Low Shear Stress Mediated by MAPK Signaling
In this study, researchers examined the effect of shear stress on human mesenchymal stem cell migration and the role of mitogen-activated protein kinases (MAPKs) in their migration. [Stem Cells Dev] Abstract

Combined Effect of Osteopontin and BMP-2 Derived Peptides Grafted to an Adhesive Hydrogel on Osteogenic and Vasculogenic Differentiation of Marrow Stromal Cells
The objective of this work was to investigate the combined effect of grafting the peptide corresponding to amino acid residues 162-168 of osteopontin and the peptide corresponding to amino acid residues 73-92 of bone morphogenetic protein-2 (BMP-2) to an RGD-conjugated inert hydrogel on osteogenic and vasculogenic differentiation of bone marrow stromal cells. [Langmuir] Abstract

GSK3 Inhibitor-BIO Regulates Proliferation of Immortalized Pancreatic Mesenchymal Stem Cells (iPMSCs)
To determine whether the small molecule 6-bromoindirubin-30-oxime (BIO), a glycogen synthase kinase 3 (GSK3) inhibitor, is involved in controlling the proliferation of iPMSCs, researchers examined the effect of BIO on iPMSCs. [PLoS One] Abstract

Cooperation of Epac1/Ras-Related Protein 1/Akt and PKA in Prostaglandin E2-Induced Proliferation of Human Umbilical Cord Blood Derived Mesenchymal Stem Cells: Involvement of c-Myc and Vascular Endothelial Growth Factor Expression
Researchers investigated the relationship between the exchange protein directly activated by cAMP (Epac1) and protein kinase A (PKA) during prostaglandin E2-induced human umbilical cord blood-derived mesenchymal stem cells proliferation and its related signaling pathways. [J Cell Physiol] Abstract

Recapitulation of Mesenchymal Condensation Enhances In Vitro Chondrogenesis of Human Mesenchymal Stem Cells
Researchers hypothesized that ‘priming’ human mesenchymal stem cells to recapitulate mesenchymal condensation events prior to inducing differentiation would enhance their subsequent chondrogenic properties. [J Cell Physiol] Abstract
