Lymphotoxin-β Receptor Signaling through NF-κB2-RelB Pathway Reprograms Adipocyte Precursors as Lymph Node Stromal Cells
Researchers showed that embryonic mesenchymal cells with characteristics of adipocyte precursors present in the microenvironment of lymph nodes gave rise to lymph node organizer cells. Signaling through the lymphotoxin-β receptor controlled the fate of adipocyte precursor cells by blocking adipogenesis and instead promoting lymphoid tissue stromal cell differentiation.

PTEN Loss in the Myf5 Lineage Redistributes Body Fat and Reveals Subsets of White Adipocytes that Arise from Myf5 Precursors
The developmental origin of adipose tissue and what controls its distribution is poorly understood. By lineage tracing and gene expression analysis in mice, scientists provided evidence that mesenchymal precursors expressing Myf5, which are thought to give rise only to brown adipocytes and skeletal muscle, also give rise to a subset of white adipocytes. [Cell Metab] Abstract

Effective Combination Therapy for Malignant Glioma with TRAIL-Secreting Mesenchymal Stem Cells and Lipoxygenase Inhibitor MK886
The apoptotic ligand TRAIL is believed to have promise as a cancer gene therapy, yet many types of cancer, including gliomas, have exhibited resistance to TRAIL-induced apoptosis. Researchers showed that therapeutic combination of the lipoxygenase inhibitor MK886 and TRAIL-secreting human mesenchymal stem cells provide targeted and prolonged delivery of TRAIL both in vitro and in orthotopic mouse models of glioma. [Cancer Res] Abstract

Macrophages Regulate Smooth Muscle Differentiation of Mesenchymal Stem Cells via a Prostaglandin F2α-Mediated Paracrine Mechanism

To explore the role of macrophages on mesenchymal stem cell-mediated vascular regeneration, researchers examined the effects of IL-1β-activated macrophages on differentiation of human adipose tissue-derived mesenchymal stem cells to smooth muscle cells (SMCs) and the vascular regenerative capacity of the differentiated SMCs in a hindlimb ischemia animal model.

Marrow-Derived Stromal Cell Delivery on Fibrin Microbeads Can Correct Radiation-Induced Wound-Healing Deficits
Previous attempts to administer dermal cells locally to wounds to correct radiation-induced deficits were hampered by poor cell retention. Researchers improved the outcome by using biodegradable fibrin microbeads (FMBs) to isolate a population of mesenchymal marrow-derived stromal cells (MSCs) from murine bone marrow by their specific binding to the fibrin matrix, cultured them to high density in vitro, and delivered them as MSCs on FMBs at the wound site.

Therapeutic Effects of hMAPC and hMSC Transplantation after Stroke in Mice
Researchers assessed the effect of human multipotent adult progenitor cells (hMAPCs) and human mesenchymal stem cells (hMSCs) on endogenous neurogenesis, angiogenesis and inflammation following stroke. [PLoS One] Full Article

Mesenchymal Stem Cells in Inflammation Microenvironment Accelerates Hepatocellular Carcinoma Metastasis by Inducing Epithelial-Mesenchymal Transition
Scientists demonstrated that mesenchymal stem cells (MSCs) promote human hepatocellular carcinoma metastasis under the influence of inflammation. The metastasis promoting effect could be imitated with the supernatant of MSCs pretreated with IFNγ and TNFα. [PLoS One]

TIMP3 or VEGF Transfection of Aged Human MSCs Enhances Cell Therapy after Myocardial Infarction
The authors genetically engineered old human mesenchymal stem cells (MSCs) with tissue inhibitor of matrix metalloproteinase-3 (TIMP3) and vascular endothelial growth factor (VEGF) and evaluated the effects on the efficacy of cell-based gene therapy in a rat myocardial infarction model. [Rejuvenation Res]

Mesenchymal Stem Cell Therapy Promotes Renal Repair by Limiting Glomerular Podocyte and Progenitor Cell Dysfunction in Adriamycin-Induced Nephropathy
Repeated injections of mesenchymal stem cells (MSCs) limited podocyte loss and apoptosis, and partially preserved nephrin and CD2AP in adriamycin-rats. MSCs attenuated the formation of glomerular podocyte-parietal epithelial cell bridges and normalized the distribution of NCAM+progenitor cells along the Bowman’s capsule, thereby reducing glomerulosclerosis. [Am J Physiol Renal Physiol] Abstract

Mesenchymal Stem Cell Transplantation Improves Regional Cardiac Remodeling following Ovine Infarction
Data demonstrated that bone marrow-derived mesenchymal stem cell implantation improved cardiac remodeling in the region adjacent to the infarct after cardiac infarction in the ovine infarction model. [Stem Cells Transl Med] Abstract | Press Release
