TOP STORY
The Osteogenic Differentiation of SSEA-4 Sub-Population of Human Adipose Derived Stem Cells Using Silicate Nanoplatelets
Silicate nanoplatelets (sNPs) were used to promote the osteogenic differentiation of SSEA-4+ human adipose derived stem cells (SSEA-4+ hASCs). The interactions between SSEA-4+ hASCs and sNPs, namely the internalization pathway and effect on cells osteogenic differentiation, were evaluated. [Biomaterials] Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
Curcumin-Functionalized Silk Materials for Enhancing Adipogenic Differentiation of Bone Marrow-Derived Human Mesenchymal Stem Cells
Curcumin, a natural phenolic compound derived from the plant Curcuma longa, was physically entrapped and stabilized in silk hydrogel films and its influence on human bone marrow-derived mesenchymal stem cells was assessed related to adipogenic differentiation. [Acta Biomater] Abstract

Combinatorial Gene Therapy Accelerates Bone Regeneration: Non-Viral Dual Delivery of VEGF and BMP2 in a Collagen-Nanohydroxyapatite Scaffold
Vascularization and bone repair are accelerated by a series of gene-activated scaffolds delivering both an angiogenic and an osteogenic gene. Stem cell-mediated osteogenesis in vitro, in addition to increased vascularization and bone repair by host cells in vivo, is enhanced using all systems while the use of the nanohydroxyapatite vector to deliver both genes markedly enhances bone healing. [Adv Healthc Mater] Abstract

Combination of ADMSCs and Chondrocytes Reduces Hypertrophy and Improves the Functional Properties of Osteoarthritic Cartilage
Scientists evaluated the therapeutic efficacy of ADMSCs in combination with chondrocytes in counteracting oxidative stress in chondrocytes in vitro and in rat model of osteoarthritis. [Osteoarthritis Cartilage] Abstract

ABCG2pos Lung Mesenchymal Stem Cells Are a Novel Pericyte Subpopulation that Contributes to Fibrotic Remodeling
Resident lung mesenchymal stem cells were quantified in lung samples from control subjects and pulmonary fibrosis (PF) patients. ABCG2pos cell numbers were decreased in human PF and interstitial lung disease compared to control samples. [Am J Physiol Cell Physiol] Abstract

The Effect of Lentivirus-Mediated PSPN Genetic Engineering Bone Marrow Mesenchymal Stem Cells on Parkinson’s Disease Rat Model
Researchers assessed the potential therapeutic function of gene-modified mesenchymal stem cells (MSCs)-Lv-persephin (PSPN)-MSCs in 6-OHDA-induced Parkinson’s disease rat models. They worked on the isolation, purification, identification and amplification of MSCs in vitro. [PLoS One] Full Article

Human Adipose-Derived Mesenchymal Stem Cells Improve Motor Functions and Are Neuroprotective in the 6-Hydroxydopamine-Rat Model for Parkinson’s Disease when Cultured in Monolayer Cultures but Suppress Hippocampal Neurogenesis and Hippocampal Memory Function when Cultured in Spheroids
Researchers compared monolayer-cultured and spheroid mesenchymal stem cells following transplantation into the substantia nigra of 6-OHDA lesioned rats regarding effects on the local microenvironment, degeneration of dopaminergic neurons, neurogenesis in the hippocampal dentate gyrus as well as motor and memory function in the 6-OHDA-rat model for Parkinson´s disease. [Stem Cell Rev] Abstract

Downregulated CXCL12 Expression in Mesenchymal Stem Cells Associated with Severe Aplastic Anemia in Children
Scientists studied whether aberrant gene expression could be found in mesenchymal stem cells (MSCs) from children with severe aplastic anemia (SAA). Using microarray analysis, two different patterns of global gene expression were detected in the SAA MSCs. [Ann Hematol] Abstract

Sox2 Is a Potent Inhibitor of Osteogenic and Adipogenic Differentiation in Human Mesenchymal Stem Cells
Researchers overexpressed Sox2 in immortalized human mesenchymal stem cells by lentiviral gene transfer. Sox2 overexpression significantly reduced the osteogenic and adipogenic differentiation potentials. [Cell Reprogram] Abstract

The Effects of Synthetic Oligopeptide Derived from Enamel Matrix Derivative on Cell Proliferation and Osteoblastic Differentiation of Human Mesenchymal Stem Cells
An oligopeptide synthesized derived from enamel matrix derivative was evaluated for whether it contributes to periodontal tissue regeneration. Scientists investigated the effects of the synthetic peptide on cell proliferation and osteoblast differentiation of human mesenchymal stem cells, which are involved in tissue regeneration.

Epigenetic Rejuvenation of Mesenchymal Stromal Cells Derived from Induced Pluripotent Stem Cells
Scientists reprogrammed mesenchymal stromal cells (MSCs) into induced pluripotent stem cells (iPSCs), which were subsequently redifferentiated toward MSCs. These iPS-MSCs revealed similar morphology, immunophenotype, in vitro differentiation potential, and gene expression profiles as primary MSCs. [Stem Cell Rep] Full Article | Graphical Abstract
