1. A method of reducing spontaneous behavioral epileptic seizure activity in a mammalian subject comprising:
- (a) isolating mammalian cells from fetal telencephalon and/or mesencephalon, wherein the mammalian cells co-express nestin, Oct-4, and a marker selected from the group consisting of TRA-1-60, TRA-1-81 and SSEA-4,(b) suspending the isolated mammalian cells in a culture medium that has a total calcium concentration of 0.03 to 0.15 mM,(c) transplanting the suspended mammalian cells of step (b) into a cerebral ventricle of the subject who has had a seizure within the preceding week, and(d) measuring spontaneous behavioral epileptic seizures in the mammalian subject treated with the transplanted cells of step (c), wherein spontaneous behavioral epileptic seizure activity is reduced following transplantation.

Abstract
Pluripotent cells that are immunopositive for both the neural progenitor marker nestin and a pluripotent cell marker are provided. The cells exhibit rapid doubling times and can be maintained in vitro for extended periods. Also provided are cell cultures containing the pluripotent cells, a method of transplanting human pluripotent cells to a host, and a method of reducing seizure activity in a subject. These pluripotent cells, when transplanted into the ventricle of a host animal, migrate to the site of damage and adopt a suitably corrective phenotype, resulting in both structural and functional restoration.
