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.

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.

Downregulation of Melanoma Cell Adhesion Molecule(MCAM/CD146) Accelerates Cellular Senescence in Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells.
This study provides strong evidence that CD146 is a novel and useful marker for predicting senescence in human UCB-MSCs, and CD146 can potentially be applied in quality-control assessments of human UCB-MSC-based therapy.

Comparative analysis of human mesenchymal stem cells from bone marrow, adipose tissue, and umbilical cord blood as sources of cell therapy.
Mesenchymal stem cells are isolated and cultured from various sources such as bone marrow, cord blood and fat. This study compared surface antigen expression, differentiation ability, proliferation capacity, clonality, tolerance for aging, and paracrine activity and identified a protein effective to treatment inflammation from cord blood derived mesenchymal stem cell.
