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.

Autocrine Action of Thrombospondin-2 Determines the Chondrogenic Differentiation Potential and Suppresses Hypertrophic Maturation of Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells.
This study indicates that the variable chondrogenic differentiation potential of human umbilical cord blood-derived mesenchymal stem cells(hUCB-MSCs) obtained from different donors is influenced by the thrombospondin-2(TSP-2) level. Additionally, TSP-2 could attenuate hypertrophy during chondrogenic differentiation of hUCB-MSCs. Thus, TSP-2 can be used as a marker to select MSCs with superior chondrogenic differentiation potential for cartilage regeneration therapy.

GDF-15 secreted from human umbilical cord blood mesenchymal stem cells delivered through the cerebrospinal fluid promotes hippocampal neurogenesis and synaptic activity in an Alzheimer’s disease model.
In this study, we elucidated that the effectiveness to repeatedly administrated hUCB-MSCs through the CSF route as well as the promotion of hippocampal neurogenesis and synaptic activity by the GDF-15 secreted from hUCB-MSCs in Alzheimer's disease model.

Conditioned Media from Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells Inhibits Melanogenesis by Promoting Proteasomal Degradation of MITF.
This study showed that conditioned media from human umbilical cord blood-derived mesenchymal stem cells inhibits melanogenesis by modulating microphthalmia-associated transcription factor(MITF) via ERK signaling pathway.

Thrombospondin-2 secreted by human umbilical cord blood-derived mesenchymal stem cells promotes chondrogenic differentiation.
Although therapeutic effect of mesenchymal stem cells on cartilage disorders is well known, a lot of studies are being progressed on its mechanism. In this study, a specific protein (TSP-2) expressed by cord blood mesenchymal cells by joint fluid component was identified and the regeneration mechanism of injured cartilage was determined by secretion of this protein.

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.

Cryopreserved Cord Blood Progenitors and Their Cell Adhesion Molecules Are Increased by Coculture With Osteoblasts and Parathyroid Hormone.
Despite the cord blood(CB) cells induces lower immunogenicity, CB transplantation is also associated with delayed neutrophil and platelet recovery relative to bone marrow transplantation. This suggests a possibility to increase the engraftment of hematopoietic cells in CB by increasing the abundances of primitive cells bearing adhesion molecules in the presence of hPTH.
