Engineering Bone Tissue from Human Embryonic Stem Cells
Researchers showed that the cultivation of human embryonic stem cell-derived mesenchymal progenitors on three-dimensional osteoconductive scaffolds in bioreactors with medium perfusion leads to the formation of large and compact bone constructs. [Proc Natl Acad Sci USA] Abstract | Press Release

Chondrogenic Differentiation of Bone Marrow-Derived Mesenchymal Stem Cells Induced by Acellular Cartilage Sheets
Researchers investigated whether acellular cartilage sheets possess a chondrogenic induction activity that may benefit cartilage engineering with multipotent stem cells. [Biomaterials] Abstract

PTH Induces Differentiation of Mesenchymal Stem Cells by Enhancing BMP Signaling
Researchers demonstrated that parathyroid hormone (PTH)‐enhancement of mesenchymal stromal/stem cell differentiation to the osteoblast lineage occurs through a PTH and lipoprotein receptor‐related protein 6 (LRP6) dependent pathway by endocytosis of LRP6/PTH1R complex, allowing enhancement of bone morphogenetic protein (BMP) signaling. [J Bone Miner Res] Abstract

A Thermosensitive Hydrogel Capable of Releasing bFGF for Enhanced Differentiation of Mesenchymal Stem Cell into Cardiomyocyte-Like Cells under Ischemic Conditions
A thermosensitive hydrogel capable of differentiating mesenchymal stem cells (MSCs) into cardiomyocyte-like cells was synthesized. Researchers demonstrated that this hydrogel may potentially be used to deliver MSCs into hearts for regeneration of heart tissue. [Biomacromolecules] Abstract

Macrophages and Mesenchymal Stromal Cells Support Survival and Proliferation of Multiple Myeloma Cells
Scientists investigated the proliferation of multiple myeloma tumor cell lines when cultured alone or together with mesenchymal stromal cells (MSCs), macrophages, or a combination of MSCs and macrophages, using the carboxyfluorescein succinimidyl ester assay. [Br J Haematol] Abstract

Bisphosphonate- and Statin-Induced Enhancement of OPG Expression and Inhibition of CD9, M-CSF, and RANKL Expressions via Inhibition of the Ras/Mitogen Activated Protein Kinase Kinase/Extracellular Signal Regulated Kinase Pathway and Activation of Mitogen Activated Protein Kinase p38 in Mouse Bone Marrow Stromal Cell Line ST2
Researchers investigated whether bisphosphonates and statins increase osteoprotegerin (OPG) expression and inhibit the expression of CD9, macrophage colony-stimulating factor (M-CSF), and receptor activator of the NF-κB ligand (RANKL) in the bone marrow-derived stromal cell line ST2. [Mol Cell Endocrinol] Abstract

Nanog Promotes Osteogenic Differentiation of the Mouse Mesenchymal Cell Line C3H10T1/2 by Modulating Bone Morphogenetic Protein Signaling
Researchers examined the effect of forced Nanog expression in mesenchymal cells, with a particular focus on osteogenic differentiation. [J Cell Physiol] Abstract

Evaluation of Methods for Cultivating Limbal Mesenchymal Stromal Cells
Scientists evaluated methods for culturing human limbal mesenchymal stromal cells. [Cytotherapy] Abstract
