- 1. A method of treating a behavioral or psychological deficit in an animal which comprises intracerebral transplantation of a therapeutically effective amount of pluripotent neuroepithelial cells to said animal.
- 13. Pluripotent, neuroepithelial cells for therapeutic treatment of an animal.
- 25. A conditionally immortal, pluripotent, neuroepithelial cell line for therapeutic treatment of an animal.

35. A process for the production of human, conditionally immortal, pluripotent, neuroepithelial cells which comprises the steps of:
-
(a) obtaining neuroepithelial cells from a human fetus, said neuroepithelial cells being at a stage early enough in the developmental pathway that said neuroepithelial cells have the ability to differentiate into a variety of different brain cell types;
(b) introducing into said neuroepithlial cells DNA which comprises a sequence capable of causing said neuroepithlial cells to be conditionally immortal under the control of appropriate control elements; and
(c) maintaining said neuroepithelialcells in vitro under permissive conditions. - View Dependent Claims (36)
-
- 40. A method of testing comprising maintaining a population of cells of a conditionally immortal pluripotent neuroepithelial cell line in vitro and culturing portions of said cells under permissive conditions in the presence and absence of a growth factor and determining the proliferation of the cells.
- 43. A cell line comprising conditionally immortal, pluripotent, neuroepithelial stem cells, wherein said cell line is obtainable by culturing said stem cells under permissive conditions in serum-free medium.
- 49. A method of treating an animal having a damaged brain, said method comprising intracerebral transplantation of a therapeutically effective amount of a cell line into the damaged brain of said animal, said cell line comprising conditionally immortal, pluripotent, neuroepithelial stem cells, wherein said cell line is obtainable by culturing said stem cells under permissive conditions in serum-free medium into the damaged brain of said animal.
- 52. A method for treating a behavioral or psychological deficit caused by damage to, or loss of, brain cells in a mammal which comprises intracerebral transplantation to said mammal of undifferentiated pluripotent cells having neuronal and glial potential, wherein said transplanted cells migrate and differentiate to replace, or compensate for, said lost or damaged brain cells.
