Patent ID: 8039224

Claim:
A method of selecting a dopaminergic neuron precursor cell, wherein the method comprises the step of contacting a cell sample thought to comprise a dopaminergic neuron precursor cell with a peptide comprising at least an extracellular portion of a polypeptide encoded by a polynucleotide comprising a sequence selected from: (i) a nucleotide sequence comprising nucleotides 178 to 2280 of SEQ ID NO: 1 or nucleotides 127 to 2079 of SEQ ID NO: 2; (ii) a nucleotide sequence encoding the amino acid sequence of SEQ ID NO: 3 or 4; (iii) a nucleotide sequence encoding an amino acid sequence comprising residues 18 to 700 of SEQ ID NO: 3 or residues 18 to 650 of SEQ ID NO: 4; and (iv) a nucleotide sequence encoding an amino acid sequence which has 80% or more identity with the amino acid sequence of SEQ ID NO: 3 or 4, and selecting cells that bind to the peptide.
