Making neural cells for human therapy or drug screening from human embryonic stem cells
First Claim
1. A method for producing a neural cell population from human embryonic stem (hES) cells, comprising culturing hES cells in a medium containing one or more added neurotrophins and one or more added nitrogens, thereby producing a population in which at least 60% of the cells express A2B5, polyslalylated NCAM, MAP-2, or Nestin.

Abstract
This invention provides populations of neural progenitor cells, differentiated neurons, glial cells, and astrocytes. The populations are obtained by culturing stem cell populations (such as embryonic stem cells) in a cocktail of growth conditions that initiates differentiation, and establishes the neural progenitor population. The progenitors can be further differentiated in culture into a variety of different neural phenotypes, including dopaminergic neurons. The differentiated cell populations or the neural progenitors can be generated in large quantities for use in drug screening and the treatment of neurological disorders.

- 21. A method for producing a neural cell population from human embryonic stem (hES) cells, comprising initialing differentiation of the hES cells into a heterogeneous population of precursor cells, then culturing the initiated cells in a medium containing one or more added neurotrophins and one or more added mitogens, thereby producing a population in which at least 60% of the cells express A2B5, polysialylated NCAM, MAP-2, or Nestin.
