In vitro generation of GABAergic neurons from pluripotent stem cells
First Claim
1. A method of generating a differentiated neural cell population from mammalian pluripotent stem cells comprising the following steps:
- (a) expanding a culture of pluripotent stem cells;
(b) culturing the pluripotent stem cells to select for neuroprogenitor cells that are positive for nestin;
(c) isolating the nestin-positive cells;
(d) expanding the nestin-positive neuroprogenitor cells; and
(e) differentiating the nestin-positive cells to generate a differentiated cell population by culturing the cells in a differentiation media which comprises cytosine β
-d-Arabino furanoside (Ara-C).

Abstract
The present disclosure is directed to improved methods for efficiently producing neuroprogenitor cells and differentiated neural cells such as GABAergic neurons from pluripotent stem cells, for example embryonic stem cells. Using the disclosed methods, cell populations containing a high proportion of GABAergic neurons have been isolated. The neuroprogenitor cells and terminally differentiated cells of the present disclosure can be generated in large quantities, and therefore may serve as an excellent source for cell replacement therapy in neurodegenerative disorders and neuronal diseases such as stroke, ischemia, epilepsy, and Huntington'"'"'s disease.
