Estrogen Receptor Mediates Simvastatin-Stimulated Osteogenic Effects in Bone Marrow Mesenchymal Stem Cells
Investigators hypothesized that the estrogen receptor (ER) mediates simvastatin-induced osteogenic differentiation. ER antagonists and siRNA were used to determine the involvement of the ER in simvastatin-induced osteogenesis in mouse bone marrow mesenchymal stem cells. [Biochem Pharmacol] Abstract

Preameloblast-Derived Factors Mediate Osteoblast Differentiation of Human Bone Marrow Mesenchymal Stem Cells via Runx2-Osterix-BSP Signaling
The authors investigated the effects of preameloblast-conditioned medium on human bone marrow mesenchymal stem cells in vitro, and investigated the bone regenerative capacity in vivo through epithelial-mesenchymal interactions of developmental osteogenesis. [Tissue Eng Part A] Abstract

In Vitro Migration and Proliferation (“Wound Healing”) Potential of Mesenchymal Stromal Cells Generated from Human CD271⁺ Bone Marrow Mononuclear Cells
The in vitro model of wound healing was used in order to compare the migration and proliferation potential of mesenchymal stromal cells (MSCs) generated from positively selected CD271⁺ bone marrow mononuclear cells and MSCs generated by plastic adherence of passage two and four cultured in presence or absence of growth factors or cytokines.

MicroRNA-498 Inhibition Enhances the Differentiation of Human Adipose-Derived Mesenchymal Stem Cells into Podocyte-Like Cells
The authors established a two-stage induction protocol for podocytes generation from human adipose-derived mesenchymal stem cells (hAD-MSCs). They initially established a condition that induce hAD-MSCs toward intermediate mesoderm cells with activin A and high concentration of RA. [Stem Cells Dev] Abstract

IL-21-Expressing Mesenchymal Stem Cells Prevent Lethal B-Cell Lymphoma through Efficient Delivery of IL-21, which Redirects the Immune System to Target the Tumor
The authors hypothesized that mesenchymal stem cells, genetically modified to express high levels of interleukin (IL)-21, can enhance anti-tumor responses through localized delivery of IL-21. [Stem Cells Dev] Abstract

Differential Osteogenic Potential of Human Adipose-Derived Stem Cells Co-Cultured with Human Osteoblasts on Polymeric Microfiber Scaffolds
The osteogenic potential of human adipose derived stem cells (HADSCs) co-cultured with human osteoblasts (HOBs) using selected HADSCs/HOBs ratios of 1:1, 2:1 and 1:2 respectively was evaluated. [J Biomed Mater Res A] Abstract

Mesenchymal Stromal Cells for Sphincter Regeneration: Role of Laminin Isoforms upon Myogenic Differentiation
The laminin family consists of 16 functionally different isoforms with LM-211 being the most abundant isoform of adult muscle tissues. All laminin isoforms tested showed a significant inhibition of the proliferation of undifferentiated mesenchymal stromal cells (MSCs) but, with the exception of LM-521, they had no influence on the proliferation of MSCs cultivated in myogenic medium.

Disparate Effects of Mesenchymal Stem Cells in Experimental Autoimmune Encephalomyelitis and Cuprizone-Induced Demyelination
As the pathogeneses of multiple sclerosis and experimental autoimmune encephalomyelitis are thought to be mediated by IFNγ-producing and IL-17A-producing effector CD4⁺ T cells, scientists investigated the effect of mesenchymal stem cells on the development of these two key pathogenic cell groups.

Mesenchymal Stem Cells of Different Origin: Comparative Evaluation of Proliferative Capacity, Telomere Length and Pluripotency Marker Expression
The authors characterized and compared proliferation, differentiation, telomere length and pluripotency marker expression in mesenchymal stem cells of various origins. [Life Sci] Abstract

Therapeutic Application of Mesenchymal Stem Cells in Osteoarthritis
The authors present a special focus on the types of extracellular vesicles that are produced by mesenchymal stem cells (MSCs) and their role in the paracrine activity of MSCs. They then discuss the therapeutic approaches that have been evaluated in pre-clinical models of osteoarthritis (OA) and the results coming out from the clinical trials in patients with OA.
