Open the CIPO recordAbstract From the Canadian patent
Methods are described for the enhancement and/or induction of migration of neural stem cells or neuronal progenitor cells. Multipotent neural stem cells are exposed to erythropoietin which enhances the migration of multipotent neural stem cells and neuronal progenitor cells. The erythropoietin may be exogenously applied to the multipotent neural stem cells or alternatively, the cells can be subjected to hypoxic insult which induces the cells to express erythropoietin. In a preferred embodiment additional growth factors, such as EGF and prolactin are utilized.
