Endothelial Cells Direct Human Mesenchymal Stem Cells for Osteo- and Chondro-Lineage Differentiation through Endothelin-1 and AKT Signaling
Scientists investigated whether co-cultured human aortic endothelial cells were able to regulate expression of potency- and lineage-related markers in bone marrow-derived human mesenchymal stem cells. [Stem Cell Res Ther] Full Article

Comparative Analysis of Mesenchymal Stem Cell and Embryonic Tendon Progenitor Cell Response to Embryonic Tendon Biochemical and Mechanical Factors
The authors examined the effects of factors involved in embryonic tendon development on adult mesenchymal stem cells (MSCs), and compared MSC responses to that of embryonic tendon progenitor cells, a model system of tenogenically differentiating cells. [Stem Cell Res Ther] Full Article

Osteogenic Differentiation of Human MSCs: Specific Occupancy of the Mitochondrial DNA by NFATc1 Transcription Factor
Scientists investigated the recruitment of Slug and NFATc1 at the D-loop regulatory region of mitochondrial DNA in osteogenic differentiated human mesenchymal stem cells with the aim of exploring whether Slug and NFATc1 also act as mitoTFs in the mitochondrial pool of nuclear transcription factors. [Int J Biochem Cell Biol] Abstract

Cysteamine Treatment Restores the In Vitro Ability to Differentiate along the Osteoblastic Lineage of Mesenchymal Stromal Cells Isolated from Bone Marrow of a Cystinotic Patient
The authors tested the phenotypical and functional properties of cystinotic mesenchymal stromal cells isolated from bone marrow aspirate of a patient with nephropathic cystinosis. Morphology, proliferative capacity, immunophenotype and immunomodulatory properties were analyzed. [J Transl Med] Abstract | Full Article

Growth Hormone Action Influences Adipogenesis of Mouse Adipose Tissue-Derived Mesenchymal Stem Cells
Scientists elucidated the role of growth hormone (GH) on adipose tissue derived mesenchymal stem cells adipogenesis using cells isolated from male GH receptor gene knockout, bovine GH transgenic and wild-type littermate control mice. [J Endocrinol] Abstract

High Glucose Induces Bone Marrow-Derived Mesenchymal Stem Cell Senescence by Upregulating Autophagy
Researchers investigated the role of high glucose (HG)-induced autophagy in bone-marrow-derived mesenchymal stem cell senescence. HG increased expression of Beclin-1, Atg 5, 7 and 12, generation of LC3‑II and autophagosome formation which was correlated with development of cell senescence. [PLoS One] Full Article

The Effects of α-Zearalanol on the Proliferation of Bone-Marrow-Derived Mesenchymal Stem Cells and Their Differentiation into Osteoblasts
Investigators explored the effects of α-zearalanol on the proliferation of mouse bone-marrow-derived mesenchymal stem cells and their differentiation into osteoblasts. [J Bone Miner Metab] Abstract

Anti-Senescence Effects of DNA Methyltransferase Inhibitor RG108 in Human Bone Marrow Mesenchymal Stromal Cells
Researchers used a DNA methyltransferase inhibitor, RG108, to investigate the senescence effects in human bone marrow mesenchymal stromal cells. [Biotechnol Appl Biochem] Abstract
