TOP STORY
Primary Mesenchymal Stem and Progenitor Cells from Bone Marrow Lack Expression of CD44
Researchers suggest that bone marrow mesenchymal stem cells (MSCs) physiologically lack expression of CD44, highlighting the natural phenotype of MSCs and open new possibilities to prospectively isolate MSCs from the bone marrow. [J Biol Chem] Abstract | Full Article

PUBLICATIONS (Ranked by impact factor of the journal)

Role of Subnano-, Nano- and Submicron-Surface Features on Osteoblast Differentiation of Bone Marrow Mesenchymal Stem Cells
This study systematically controlled titanium surface features from the sub-nano to sub-micron scales and investigated the corresponding effects on stem cell responses, such as integrin activation, cyclins, key transcriptional genes of osteoblast differentiation and osteoblastic phenotype genes. [Biomaterials] Abstract

G-CSF Stimulation of Bone Marrow Mesenchymal Stromal Cells Promotes CD34+ Cell Migration via a Matrix Metalloproteinase-2-Dependent Mechanism

Investigators showed that the granulocyte-colony stimulating factor (G-CSF) receptor is expressed by human bone marrow mesenchymal stromal/stem cells (MSCs) and that G-CSF pre-stimulation of MSCs enhances the in vitro trans-stromal migration of CD34+ cells. [Stem Cells Dev] Abstract

Diverse Effects of Cyclic AMP Variants on Osteogenic and Adipogenic Differentiation of Human Mesenchymal Stromal Cells
Scientists investigated the role of cyclic AMP/protein kinase A signaling in differentiation of human mesenchymal stromal cells. [Tissue Eng Part A] Abstract

Donor Age of Human Platelet Lysate Affects Proliferation and Differentiation of Mesenchymal Stem Cells
Researchers support the notion that aging is associated with systemic feedback mechanisms acting on stem and progenitor cells, and suggest this is also relevant for serum supplements in cell culture: human platelet lysates derived from younger donors facilitate enhanced expansion and more pronounced osteogenic differentiation. [PLoS One] Full Article

Mesenchymal Stem Cells-Derived Interleukin-6 and Vascular Endothelial Growth Factor Promote Breast Cancer Cell Migration
By using a small panel of breast cancer cell lines, researchers analyzed the role of interleukin-6 and vascular endothelial growth factor A in the cross-talk between mesenchymal stem cells and breast cancer cells. [J Cell Biochem] Abstract

Recombinant Human Bone Morphogenetic Protein-2 Released from Polyurethane-Based Scaffolds Promotes Early Osteogenic Differentiation of Human Mesenchymal Stem Cells
Researchers aimed to investigate the pharmacokinetics of recombinant human bone morphogenetic protein-2 (rhBMP-2) from a polyurethane-based porous scaffold and to determine the biological responses of human mesenchymal stem cells to the rhBMP-2 released from those scaffolds. [Biomed Mater]
Abstract

Amelogenin Enhances the Osteogenic Differentiation of Mesenchymal Stem Cells Derived from Bone Marrow
Scientists examined the effect of recombinant human full-length amelogenin on the osteogenic differentiation of cultured human mesenchymal stem cells. [Cells Tissues Organs] Abstract

Effect of Growth Differentiation Factor 5 on the Proliferation and Tenogenic Differentiation Potential of Human Mesenchymal Stem Cells In Vitro
 
Researchers investigated cell proliferation and tenogenic differentiation in human mesenchymal stem cells exposed to different concentrations of growth differentiation factor 5. [Cells Tissues Organs] Abstract
