Human umbilical cord blood is a rich source of pluripotent mesenchymal stem cells and possesses significant advantages over other stem cell sources such as the embryo and bone marrow. In the present study, we aimed to investigate the potential of human umbilical cord blood-derived pluripotent mesenchymal stem cells (hUCB) to myelinate the axons of shiverer mice brains. We also investigated the effect of hUCB treatment on regulation of myelin basic protein in vitro in PC-12 cells, which are normally not myelinated. The results of our study clearly demonstrated that hUCB survive and migrate in vivo and has the potential to myelinate shiverer mice brains. The expression level of myelin basic protein, a major component of the myelin sheath, has been significantly increased in vivo and in vitro as revealed by Western blot, reverse transcription (RT)-polymerase chain reaction, immunohistochemistry, immunocytochemistry, and fluorescent in situ hybridization results. Further, transmission electron microscopic images of hUCB-treated shiverer mice brains showed several layers of myelin around the axons compared with a thin and fragmented layer of myelin in untreated animals. Moreover, the frequency of shivering was diminished 1 month after hUCB treatment in shiverer mice. Our results strongly indicated that hUCB transplantation could be an effective means of treating demyelinating or hypomyelinating disorders.
