Abstract

Neural stem cells (NSCs)of the central nervous system (CNS) have recently received a great deal of attention and interest for their therapeutic potential for neurological disorders. NSCs are defined as CNS progenitor cells that have the capacity for self-renewal and multipotent potential to become neurons or glial cells. Recent studies have shown that NSCs isolated from mammalian CNS including human can be propagated in vitro and then implanted into the brain of animal models of human neurological disorders. Recently, we have generated clonally derived immortalized human NSC cell lines via a retroviral vector encoded with v-myc oncogene. One of the human NSC lines, HB1.F3, was utilized in stem-cell based therapy in animal models of human neurological disorders. When F3 human NSCs were implanted into the brain of murine models of lysosomal storage diseases, stroke, Parkinson disease, Huntington disease or stroke, implanted F3 NSCs were found to migrate to the lesion sites, differentiate into neurons and glial cells, and restore functional deficits found in these neurological disorders. In animal models of brain tumors, F3 NSCs could deliver a bioactive therapeutically relevant molecules to effect a significant anti-tumor response intracranial tumor mass. Since these genetically engineered human NSCs are immortalized and continuously multiplying, there would be limitless supply of human neurons for treatment for patients suffering from neurological disorders including stroke, Parkinson disease, Huntington disease, ALS, multiple sclerosis and spinal cord injury. The promising field of stem cell research as it applies to regenerative medicine is still in infancy, but its potential appears limitless, and we are blessed to be involved in this exciting realm of research.
