TOP STORY
Mesenchymal-Stem-Cell-Induced Immunoregulation Involves FAS-Ligand-/FAS-Mediated T Cell Apoptosis
Researchers showed that in mice, systemic infusion of bone marrow mesenchymal stem cells induced transient T cell apoptosis via the FAS ligand-dependent FAS pathway and could ameliorate disease phenotypes in fibrillin-1 mutated systemic sclerosis and dextran-sulfate-sodium-induced experimental colitis.

Bone Marrow-Derived Mesenchymal Stem Cells Promote Colorectal Cancer Progression through Paracrine Neuregulin 1/Human Epidermal Growth Factor Receptor 3 Signaling
Bone marrow-derived mesenchymal stem cells migrate to primary tumors and drive tumor progression. Researchers aimed to identify the molecular mechanisms associated with these heterotypic cellular interactions and analyze their relevance in colorectal cancer. [Gut] Abstract

Adult and Umbilical Cord Blood-Derived Platelet-Rich Plasma for Mesenchymal Stem Cell Proliferation, Chemotaxis, and Cryo-Preservation

To compare the ability of various platelet-rich plasma (PRP) products to stimulate proliferation of human bone marrow (BM), rat BM and compact bone-derived mesenchymal stem cells, cells were cultured in serum-free media for four and seven days with varying concentrations of PRP, platelet-poor plasma, or combinations of recombinant mitogens. [Biomaterials] Abstract

Equal Modulation of Endothelial Cell Function by Four Distinct Tissue-Specific Mesenchymal Stem Cells
Scientists demonstrated that tissue-resident mesenchymal stem cells isolated from four distinct tissues have equal capacity to modulate endothelial cell function, including formation of vascular networks in vivo. [Angiogenesis] Abstract

Control of Mesenchymal Lineage Progression by MicroRNAs Targeting the Skeletal Gene Regulators Tricho-Rhino-Phalangeal Syndrome 1 and Runt-Related Transcription Factor 2

Investigators suggested a program of multiple microRNAs controls mesenchymal lineage progression by selectively blocking differentiation of osteoblasts and chondrocytes to control skeletal development. [J Biol Chem] Abstract

Human Amniotic Mesenchymal Stem Cell-Derived Induced Pluripotent Stem Cells May Generate a Universal Source of Cardiac Cells
Researchers investigated the reprogramming efficiency of partially pluripotent human amniotic mesenchymal stem cells (hAMSCs) to generate hAMSC-derived induced pluripotent stem cells (MiPSCs), immunomodulatory properties of the hAMSCs and MiPSCs, and cardiac differentiation potential of the MiPSCs. [Stem Cells Dev] Abstract


Differentiation-Dependent Secretion of Proangiogenic Factors by Mesenchymal Stem Cells
Researchers hypothesized that the proangiogenic potential of mesenchymal stem cells was dependent upon their stage of osteogenic differentiation. [PLoS One] Abstract

Resveratrol Mediated Modulation of Sirt-1/Runx2 Promotes Osteogenic Differentiation of Mesenchymal Stem Cells: Potential Role of Runx2 Deacetylation
This study determined whether activation of Sirt-1 by the phytoestrogen resveratrol affects osteogenic differentiation. [PLoS One] Abstract

Tubular Perfusion System Culture of Human Mesenchymal Stem Cells on Poly-L-Lactic Acid Scaffolds Produced Using a Supercritical Carbon Dioxide-Assisted Process
Scientists investigated how scaffold microstructure influences human mesenchymal stem cell behavior in a perfusion bioreactor system. [J Biomed Mater Res A] Abstract

Functional Interaction between Mesenchymal Stem Cells and Spiral Ligament Fibrocytes
To elucidate the mechanism of spiral ligament fibrocyte (SLF) repair and to determine the contribution of transplanted mesenchymal stem cells (MSCs) in this model, researchers investigated the mutual effects on differentiation and proliferation between MSCs and SLFs in a coculture system. [J Neurosci Res] Abstract

[New Webinar] Discover How to Reduce Variability in Primary Neuron Cultures with NeuroCult SM

FDA Approves Votrient® for Treatment of Patients with Certain Types of Advanced Soft Tissue Sarcoma
GlaxoSmithKline plc announced that the U.S. Food and Drug Administration (FDA) has approved Votrient® for the treatment of patients with advanced soft tissue sarcoma who have received prior chemotherapy. Soft tissue sarcomas constitute a group of rare cancers arising from mesenchymal cells. [PR Newswire]
