MicroRNA-302 Induces Proliferation and Inhibits Oxidant-Induced Cell Death in Human Adipose Tissue-Derived Mesenchymal Stem Cells
Scientists screened microRNAs that affected the proliferation and survival of human adipose tissue-derived mesenchymal stem cells (hADSCs). Transfection of miR-302d mimic increased cell proliferation and protected cells from oxidant-induced cell death in hADSCs, which was supported by flow-cytometric analysis.

Transplantation of Mesenchymal Stem Cells into the Renal Medulla Attenuated Salt-Sensitive Hypertension in Dahl S Rat
Investigators detected a stem cell deficiency in the renal medulla in Dahl salt-sensitive (S) rats and then tested the hypothesis that transplantation of mesenchymal stem cells into the renal medulla improves salt-sensitive hypertension in Dahl S rats. [J Mol Med] Abstract

Molecular Pathways Reflecting Poor Intrauterine Growth Are Found in Wharton’s Jelly-Derived Mesenchymal Stem Cells
Mesenchymal stem cells from small for gestational age newborns were found to express an altered EGR-1-dependent gene network involved in the regulation of cell proliferation and oxidative stress. [Hum Reprod] Abstract

Rapidly Self-Renewing Human Multipotent Marrow Stromal Cells (hMSC) Express Sialyl Lewis X and Actively Adhere to Arterial Endothelium in a Chick Embryo Model System
There have been conflicting observations regarding the receptors utilized by hMSCs to adhere to endothelial cells. To address the discrepancies, investigators performed experiments with cells prepared with a standardized, low-density protocol preserving a sub-population of small cells that are rapidly self-renewing.

MCP/CCR2 Signaling Is Essential for Recruitment of Mesenchymal Progenitor Cells during the Early Phase of Fracture Healing
The functional effect of monocyte chemotactic protein-1 (MCP-1) on primary mouse bone marrow stromal cells was evaluated using an in vitro migration assay. MCP-1^-/- and C-C chemokine receptor 2 (CCR2)^-/- mice were fractured and evaluated by histological staining and micro-computed tomography. [PLoS One] Full Article

Effect of Preemptive Treatment with Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells on the Development of Renal Ischemia-Reperfusion Injury in Mice
Investigators hypothesized that human umbilical cord blood-derived stem cells could suppress the inflammatory response in postischemic kidneys and attenuate early renal injury. [Am J Physiol Renal Physiol] Abstract

Mesenchymal Stem Cells from Osteoporotic Patients Reveal Reduced Migration and Invasion upon Stimulation with BMP-2 or BMP-7
Researchers scrutinized human mesenchymal stem cells for osteoporosis associated alterations in bone morphogenetic protein (BMP) mediated migration and invasion as well as in extracellular matrix binding integrin expression. [Biochem Biophys Res Commun] Full Article

MSC Attenuate Diabetes-Induced Functional Impairment in Adipocytes via Secretion of Insulin-Like Growth Factor-1
Researchers hypothesized that mesenchymal stem cell (MSC) function may involve subcutaneous adipocytes. The abnormal function of subcutaneous adipocytes from STZ induced diabetic mice including glucose uptake and free fatty acid secretion level were assessed. [Biochem Biophys Res Commun] Abstract
