Identification and Characterization of PDGFRa⁺ Mesenchymal Progenitors in Human Skeletal Muscle
Researchers previously identified non-myogenic mesenchymal progenitors that contribute to adipogenesis and fibrogenesis in mouse skeletal muscle. In this study, they report the identification and characterization of a human counterpart to these progenitors. [Cell Death Dis] Full Article

Cadherin-11 Regulates Mesenchymal Stem Cell Differentiation into Smooth Muscle Cells and Development of Contractile Function In Vivo
Scientists found that Cadherin-11 but not Cadherin-2 was necessary for mesenchymal stem cell differentiation into smooth muscle cells (SMCs). Cadherin-11 regulated expression of transforming growth factor (TGF)-ß1 and affected SMC differentiation through a TGF-ß receptor II dependent but Smad2/3 independent pathway. [J Cell Sci] Abstract

Netrin-1 Induces MMP-12-Dependent E-Cadherin Degradation via the Distinct Activation of PKCa and FAK/Fyn in Promoting Mesenchymal Stem Cells Motility
Researchers investigated the role of netrin-1 in promoting the motility of human umbilical cord blood derived mesenchymal stem cells and its related signaling pathways. [Stem Cells Dev] Abstract

Mitochondrial Transfer of Induced Pluripotent Stem Cells-Derived MSCs to Airway Epithelial Cells Attenuates Cigarette Smoke-induced Damage
Researchers investigated the potential benefit of mitochondrial transfer from human-induced pluripotent stem cell-derived mesenchymal stem cells (MSCs) to cigarette smoke-exposed airway epithelial cells in vitro and in vivo. [Am J Respir Cell Mol Biol] Abstract

Chondrogenic Phenotype of Articular Chondrocytes in Monoculture and Co-Culture with Mesenchymal Stem Cells in Flow Perfusion
Scientists investigated the effect of flow perfusion bioreactor culture with and without TGF-ß3 supplementation on the proliferation, extracellular matrix production, and chondrogenic gene expression of chondrocytes both in monoculture and in co-culture with bone marrow-derived mesenchymal stem cells. [Tissue Eng] Abstract

Effects of Enamel Matrix Derivative on the Proliferation and Osteogenic Differentiation of Human Gingival Mesenchymal Stem Cells
Recently, enamel matrix derivative (EMD) has been shown to enhance the proliferation and mineralization of human bone marrow mesenchymal stem cells. Because the gingival flap is the major component to cover the surgical wound, the effects of EMD on the proliferation and mineralization of gingiva-derived mesenchymal stem cells were evaluated.

Protein Synthesis and Secretion in Human Mesenchymal Cells Derived from Bone Marrow, Adipose Tissue and Wharton’s Jelly
Researchers isolated human mesenchymal stromal cells from bone marrow, adipose tissue and Wharton’s jelly and cultured them in fetal bovine serum supplemented media. They evaluated proliferation, in vitro differentiation, expression of cell surface markers and protein secretion using Luminex and ELISA assays. [Stem Cells Res Ther] Abstract | Full Article

Transforming Growth Factor-Beta Signaling-Dependent Alleviation of Dextran Sulfate Sodium-Induced Colitis by Mesenchymal Stem Cell Transplantation
Researchers transplanted primary mouse mesenchymal stem cells (MSC) into isogeneic mice with dextran sulfate sodium (DSS)-induced colitis. They found that MSC transplantation significantly alleviated the DSS-induced colitis. [Mol Biol Rep] Abstract

Human Umbilical Cord Blood Mesenchymal Stem Cell Transplantation Suppresses Inflammatory Responses and Neuronal Apoptosis during Early Stage of Focal Cerebral Ischemia in Rabbits
Researchers investigated the effects of human umbilical cord blood mesenchymal stem cells on inflammatory responses and neuronal apoptosis during the early stage of focal cerebral ischemia in rabbits. [Acta Pharmacol Sin] Abstract
