1. A method of producing a human neural cell comprising, a) providing a pluripotent human cell;
- b) forming an embryoid body by contacting the pluripotent human cell with an essentially serum free medium; and
c) culturing the embryoid body in an essentially serum free cell differentiation environment to thereby produce the human neural cell.

- 29. A method of producing a partially differentiated pluripotent cell comprising culturing a pluripotent cell culture on a layer of fresh feeder cells, wherein the fresh feeder cells have been plated for less than approximately 48 hours, thereby inducing formation of a more differentiated pluripotent cell.
- 36. A neural cell culture composition comprising a population of neural cells derived in vitro from pluripotent cells, wherein the neural cells express one or more detectable markers for tyrosine hydroxylase (TH), vesicular monamine transporter 2 (VMAT2), aromatic amino acid decarboxylase (AADC) and dopamine transporter (DAT).

- 40. A neural cell culture composition comprising a population of neural cells derived in vitro from pluripotent cells, wherein the neural cells express one or more detectable markers for nestin or vimentin, and the neural cells have the capacity to differentiate into cells of a neural lineage.
