Cobalt Chloride Enhances the Anti-Inflammatory Potency of Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells through the ERK-HIF-1α-MicroRNA-146a-Mediated Signaling Pathway
MSC shows therapeutic effects through paracrine secretion or intercellular contact that regulates inflammatory or immune responses. Through the asthma mouse model, this study showed that CoCl2 enhances the anti-inflammatory activity of MSC through the ERK-HIF-1a-miRNA124a pathway, and CoCl2 has better therapeutic efficacy for inflammatory diseases of pretreated MSC.

Modeling and Staging of Osteoarthritis Progression Using Serial CT Imaging and Arthroscopy
This study presents an animal model of degenerative arthritis similar to humans in which the meniscal release method can be used to induce degenerative arthritis in sheep and then, the degree of cartilage damage can be checked with CT images and arthroscopy without the sacrifice of the object to determine when to administer the therapeutic agent.

Intracellular Calcium Determines the Adipogenic Differentiation Potential of Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells via the Wnt5a/β-Catenin Signaling Pathway
Calcium enhances the ability of cord blood-derived stem cells to differentiate into fat, which is observed through Wnt5a / β-Catenin signaling. Culture conditions to improve stem cell differentiation potency were identified through the above results.

In vitro Chondrogenic Hypertrophy Induction of Mesenchymal Stem Cells
To investigate underlying mechanisms of chondrogenic hypertrophy, the inevitable result of chondrogenic differentiation of mesenchymal stem cells(MSCs), we need suitable in vitro model. This study presents a simple protocol for induction of hypertrophy during in vitro chondrogenesis of MSCs.

Senescence associated MCP-1 secretion is dependent on a decline in BMI1 in human mesenchymal stromal cells.
In the present study, we provide the first evidence supporting the existence of the MCP-1 as a causative contributor to human UCB-MSCs senescence and positive feedback between the intrinsic and extrinsic circuitry of the process. MCP-1 induction is epigenetically regulated by a reduction in BMI1 in senescent UCB-MSC.
