TOP STORY

Dual Origin of Mesenchymal Stem Cells Contributing to Organ Growth and Repair
By using genetic lineage tracing, researchers show that some pericytes differentiate into specialized tooth mesenchyme-derived
cells—odontoblasts—during tooth growth and in response to damage in vivo. [Proc Natl Acad Sci USA]

SCIENCE NEWS

Helping the Heart Help Itself
Some stem cells in the bone marrow, called c-kit+ cells, appear capable of stimulating adult stem cells already present in the heart to repair the damaged tissue. [Press release from Harvard University discussing online prepublication in Cell Stem Cell]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Bone Marrow-Derived Cell Therapy Stimulates Endogenous Cardiomyocyte Progenitors and Promotes Cardiac Repair
Findings suggest that stimulation of endogenous cardiogenic progenitor activity is a critical mechanism of cardiac cell therapy. [Cell Stem Cell]

Dose-Dependent Effects of R-Sulforaphane Isothiocyanate on the Biology of Human Mesenchymal Stem Cells, at Dietary Amounts, it Promotes Cell Proliferation and Reduces Senescence and Apoptosis, While at Anti-Cancer Drug Doses, it Has a Cytotoxic Effect
Researchers evaluated the effects of sulforaphane [(−)1-isothiocyanato-4R-(methylsulfinyl)-butane] (R-SFN) on the biology of human mesenchymal stem cells. [Age]

A Therapeutic Role for Mesenchymal Stem Cells in Acute Lung Injury Independent of Hypoxia-Induced Mitogenic Factor
In this study, researchers evaluated the therapeutic role of bone marrow mesenchymal stem cell (MSC) transplantation in lipopolysaccaride-induced acute lung injury and assessed the importance of hypoxia-induced mitogenic factor in MSC transplantation. [J Cell Mol Med]

Regeneration of Three Layers Vascular Wall by using BMP2-Treated MSC Involving HIF-1α and Id1 Expressions Through JAK/STAT Pathways
The aim of the present study was to evaluate the collaborative effect of recombinant human—BMP2 and bone marrow—mesenchymal stem cells seeded on a vascular patch to regenerate a vascular arterial wall in a rat model. [Stem Cell Rev]

Mesenchymal Stem Cell Transplantation Changes the Gene Expression Profile of the Neonatal Ischemic Brain
Researchers show for the first time that in the neonatal ischemic brain survival of transplanted mesenchymal stem cells is very limited. [Brain Behav Immun]

5-Azacytidine Induces Cardiac Differentiation of Human Umbilical Cord Derived Mesenchymal Stem Cells by Activating Extracellular Regulated Kinase (ERK)
Here, researchers demonstrated that 5-Azacytidine induced cardiac differentiation of human umbilical cord-derived mesenchymal stem cells and explored the potential signaling pathway. [Stem Cells Dev]

Paracrine Effect of Wnt11 Overexpressing Mesenchymal Stem Cells on Ischemic Injury
In this study, researchers investigated whether Wnt11 enhances mesenchymal stem cell-mediated cardioprotection via paracrine fashion following acute ischemia. [Stem Cell Dev]

Estrogen Reduces Cellular Aging in Human Mesenchymal Stem Cells and Chondrocytes
Estrogen exerts profound effects on human physiology including articular cartilage and mesenchymal stem cells. The present study should analyze the effects of pre- and postmenopausal estrogen concentrations on chondrogenic cells. [J Orthop Res]
