Mesenchymal Stem Cell Exosomes Induce the Proliferation and Migration of Normal and Chronic Wound Fibroblasts, and Enhance Angiogenesis In Vitro
Scientists examined the role of mesenchymal stem cell (MSC) exosomes in wound healing. They found that MSCs exosomes ranged from 30 to 100-nm in diameter and internalization of MSC exosomes resulted in a dose-dependent enhancement of proliferation and migration of fibroblasts derived from normal donors and chronic wound patients.

Mesenchymal Stem Cells Derived from Induced Pluripotent Stem Cells Combined with Low-Dose Rapamycin Induced Islet Allograft Tolerance via Suppressing Th1 and Enhancing Regulatory T Cell Differentiation
Investigators showed that mesenchymal stem cells derived from induced pluripotent stem cells (iPSC-MSCs) combined with rapamycin significantly prolonged islet allograft survival in the diabetic mice. Histopathological analysis revealed that iPSC-MSCs combined with rapamycin preserved the graft effectively, inhibited inflammatory cell infiltration and resulted in substantial release of insulin.

Bone Marrow Mesenchymal Stem Cell Transplantation Retards the Natural Senescence of Rat Hearts
The authors investigated the antiaging properties of bone marrow mesenchymal stem cells and the underlying mechanism in a cellular model of cardiomyocyte senescence and a rat model of aging hearts. [Stem Cells Transl Med] Abstract | Press Release

Mesenchymal-Stem-Cell-Derived Exosomes Accelerate Skeletal Muscle Regeneration
Researchers investigated the role of mesenchymal stem cell (MSC) exosomes in skeletal muscle regeneration. MSC exosomes promotes myogenesis and angiogenesis in vitro, and muscle regeneration in an in vivo model of muscle injury. [FEBS Lett] Abstract

Icariin Induces Osteogenic Differentiation of Bone Mesenchymal Stem Cells in a MAPK-Dependent Manner
Effects of icariin on cell proliferation and osteogenic differentiation of rat bone mesenchymal stem cells were systematically evaluated. To characterize underlying mechanisms, its effects on mitogen-activated protein kinase signaling pathways were determined. [Cell Prolif] Abstract

Mesenchymal Stromal Cells Derived from Acute Myeloid Leukemia Bone Marrow Exhibit Aberrant Cytogenetics and Cytokine Elaboration
Researchers characterized the cytokine and gene expression profile, immunophenotype and cytogenetics of bone marrow-derived mesenchymal stromal cells (BM-MSCs) from acute myeloid leukemia (AML) patients compared to normal BM-MSCs from healthy donors. AML BM-MSCs showed decreased monocyte chemoattractant protein-1 levels compared to normal BM-MSCs. [Blood Cancer J] Full Article

Mesenchymal Stem Cells Facilitate In Vitro Development of Human Preantral Follicle
Scientists investigated whether mesenchymal stem cells (MSCs) could help to reconstruct a microenvironment to facilitate the in vitro follicle development. They showed human MSCs significantly promotes the survival rates, increases the growth velocity, and improves the viability of preantral follicles in a dose-dependent manner. [Reprod Sci] Abstract
