Electro-Acupuncture Promotes the Survival and Differentiation of Transplanted Bone Marrow Mesenchymal Stem Cells Pre-Induced with Neurotrophin-3 and Retinoic Acid in Gelatin Sponge Scaffold after Rat Spinal Cord Transection
Mesenchymal stem cells were loaded into three-dimensional gelatin sponge scaffold. After seven days of induction with neurotrophin-3 and retinoic acid in vitro, scientists observed a significant increase in TrkC mRNA transcription by real-time PCR and this was confirmed by in situ hybridization.

Repetitive Allogeneic Intraarticular Injections of Synovial Mesenchymal Stem Cells Promote Meniscus Regeneration in a Porcine Massive Meniscus Defect Model
Researchers examined the effect of repetitive intraarticular injections of synovial mesenchymal stem cells on meniscus regeneration in a massive meniscal defect of pigs. [Osteoarthritis Cartilage] Abstract

Ethyl-3,4-Dihydroxybenzoate with a Dual Function of Induction of Osteogenic Differentiation and Inhibition of Osteoclast Differentiation for Bone Tissue Engineering
The osteoinductive ability of ethyl-3,4-dihydroxybenzoate in pre-osteoblasts and human mesenchymal stem cells was examined. [Tissue Eng Part A] Abstract

Impact of Low Oxygen Tension on Stemness, Proliferation and Differentiation Potential of Human Adipose-Derived Stem Cells
Researchers found that hypoxia increased adipose-derived stem cells stemness marker expression and proliferation rate without altering their morphology and surface markers. Low oxygen tension further enhances the chondrogenic differentiation ability, but reduces both adipogenic and osteogenic differentiation potential. [Biochem Biophys Res Commun] Abstract

The Influence of Hypoxia on the Differentiation Capacities and Immunosuppressive Properties of Clonal Mouse Mesenchymal Stromal Cell Lines
Researchers showed that a panel of continuously growing mouse mesenchymal stromal cell lines, namely OP9, MS5, PA6, ST2 and B16-14, exhibit mesenchymal stromal cell characteristic phenotypes and respond physiologically to oxygen deprivation. [Immunol Cell Biol] Abstract

Conditioned Medium from Hypoxic Bone Marrow-Derived Mesenchymal Stem Cells Enhances Wound Healing in Mice
Scientists set out to elucidate and compare the impact of normoxic and hypoxic cell-culture conditions on the expression and secretion of bone marrow-derived mesenchymal stem cell-derived paracrine molecules that hypothetically contribute to cutaneous wound healing in vivo. [PLoS One] Full Article

Human Mesenchymal Stem Cell Spheroids in Fibrin Hydrogels Exhibit Improved Cell Survival and Potential for Bone Healing
Scientists hypothesized that forming mesenchymal stem cells into more physiologic three-dimensional spheroids, rather than employing dissociated cells from two-dimensional monolayer culture, will enhance their survival when exposed to a harsh microenvironment but maintain their osteogenic potential. [Cell Tissue Res] Abstract

Comparative Analysis of Multilineage Properties of Mesenchymal Stromal Cells Derived from Fetal Sources Shows an Advantage of Mesenchymal Stromal Cells Isolated from Cord Blood in Chondrogenic Differentiation Potential
Researchers showed that cord blood-mesenchymal stromal cell (MSCs) and amniotic fluid-MSCs collected at term differ from each other in their biological and differentiation properties. [Cytotherapy] Abstract

Functional Outcome after Anal Sphincter Injury and Treatment with Mesenchymal Stem Cells
Scientists demonstrated the regenerative effects of mesenchymal stem cells (MSCs) on the injured anal sphincter by comparing anal sphincter pressures following intramuscular and serial intravascular MSC infusion in a rat model of anal sphincter injury.

C. Randal Mills Named as New President of California’s Stem Cell Agency
Describing him as a “visionary and highly regarded scientific and business leader” the California Institute for Regenerative Medicine, the state’s stem cell agency, today appointed C. Randal Mills, Ph.D., as its new President and Chief Executive Officer. [California Institute for Regenerative Medicine] Press Release

UGA to Use $5 Million Gift to Support Center for Molecular Medicine
A $5 million gift to support the Center for Molecular Medicine at the University of Georgia (UGA) will allow the institution to greatly advance its research into human disease. [University of Georgia] Press Release
