TOP STORY

Tenogenic Induction of Human MSCs by Anisotropically Aligned Collagen Biotextiles
A 3D-biotextile was woven purely from collagen. Mesenchymal stem cells (MSCs) seeded in the woven scaffold underwent tenogenic differentiation in the absence of growth factors and synthesized a matrix that is positive for tenomodulin, COMP and type I collagen. [Adv Funct Mater] Abstract

PUBLICATIONS (Ranked by impact factor of the journal)

Interleukin-17 Enhances Immunosuppression by Mesenchymal Stem Cells
Scientists examined the effect of interleukin-17 (IL-17) on mesenchymal stem cells (MSCs) under the influence of inflammatory cytokines. Ironically, IL-17 dramatically enhanced the immunosuppressive effect of MSCs induced by interferon-γ and tumor necrosis factor-α, revealing a novel role of IL-17 in immunosuppression.

Bone Marrow-Derived Clonal Mesenchymal Stem Cells Inhibit Ovalbumin-Induced Atopic Dermatitis
Using an ovalbumin-induced atopic dermatitis (AD) mouse model, researchers investigated whether mesenchymal stem cells (MSCs) can be used as therapeutics in AD. Clonal MSCs suppressed both T- and B-cell activation. [Cell Death Dis] Full Article

Inhibition of B-Cell Proliferation and Antibody Production by Mesenchymal Stromal Cells Is Mediated by T Cells
Scientists show that, both in healthy subjects and in patients, in vitro B-cell proliferation, plasma-cell differentiation and antibody production are inhibited by bone marrow-derived mesenchymal stromal cells (MSCs) when peripheral blood lymphocytes are stimulated with CpG, but not when sorted B cells are cultured with MSCs+CpG. [Stem Cells Dev] Abstract

Cell-Viability and Chondrogenic Differentiation Capability of Human Mesenchymal Stem Cells after Iron-Labelling with Iron Sucrose
Investigators determined effects on cell viability, traceability and chondrogenic differentiation of human mesenchymal stem cells after iron labelling with iron sucrose. [Stem Cells Dev] Abstract

Autologous Platelet Rich Plasma: A Biological Supplement to Enhance Adipose-Derived Mesenchymal Stem Cell Expansion
Adipose-derived mesenchymal stem cells (AT-MSCs) were cultured for ten days in media supplemented with different concentrations of autologous non-activated or thrombin-activated platelet-rich plasma. AT-MSC proliferation, cell phenotype, and multipotency capacity and chromosome stability were assessed and compared to AT-MSCs expanded in a classical medium supplemented with 10% of fetal bovine serum. [Tissue Eng Part C Methods] Abstract

Expansion of Human Mesenchymal Stromal Cells from Fresh Bone Marrow in a 3D Scaffold-Based System under Direct Perfusion
Scientists demonstrate that conventional monolayer culture on plastic dish mesenchymal stromal/stem cell expansion can be entirely bypassed by culturing freshly isolated bone marrow nucleated cells within three dimensional (3D) porous scaffolds in a perfusion-based bioreactor system. [PLoS One] Full Article

Enhanced Osteogenic Differentiation of Mesenchymal Stem Cells on Poly(L-Lactide) Nanofibrous Scaffolds Containing Carbon Nanomaterials
Carbon nanomaterials (CNM) were incorporated into nanofibrous poly(L-lactic acid) scaffolds by thermal induced phase separation. The CNM-containing composite nanofibrous scaffolds were biologically evaluated by both in vitro co-culture of bone mesenchymal stem cells and in vivo implantation. [J Biomed Mater Res A] Abstract

Overexpression of TGF-β1 Enhances Chondrogenic Differentiation and Proliferation of Human Synovium-Derived Stem Cells
Scientists investigated the effect of continuous transforming growth factor (TGF)-β1 overexpression in human synovium-derived mesenchymal stem cells (hSD-MSCs) on immunophenotype, differentiation potential, and proliferation rate. hSD-MSCs were transduced with recombinant retroviruses encoding TGF-β1. [Biochem Biophys Res Commun] Abstract

Neural Differentiation of Mesenchymal Stem Cells Influences Their Chemotactic Responses to Stromal Cell-Derived Factor-1α
Researchers demonstrated that mesenchymal stem cells in varying neural differentiation states display various chemotactic responses to stromal cell-derived factor-1α. [Cell Mol Neurobiol] Abstract

Frozen Adipose-Derived Mesenchymal Stem Cells Maintain High Capability to Grow and Differentiate
Scientists show that adipose-derived stromal cells in serum free media can easily be frozen and stored in liquid nitrogen with retention of 85% of cell viability and 180,890 cell/g yield plus normal proliferative capacity and differentiation potential compared with fresh controls. [Cryobiology] Full Article

A Novel Albumin-Based Tissue Scaffold for Autogenic Tissue Engineering Applications
Using a culture of human mesenchymal stem cells (MSCs) as a model, scientists showed that MSCs can be seeded and grown in the albumin tissue scaffold. Furthermore, the albumin tissue scaffold can support the long-term osteogenic differentiation of MSCs. [Sci Rep] Full Article

REVIEWS

Mesenchymal Stem Cells and Hypoxia: Where Are We?
The authors summarize recent knowledge on the survival of mesenchymal stromal cells (MSCs) under low oxygen conditions of varying duration and severity and to elucidate the mechanisms of MSC resistance/sensitivity to hypoxic impact. [Mitochondrion] Abstract
