Method to isolate, identify, and use embryonic stem cells directed to forebrain interneuron fate
The present invention relates to methods of isolating a purified or enriched population of cortical or striatal immature interneuron progenitor cells and the isolated purified or enriched population of immature interneuron progenitor cells. Methods of treating a condition mediated by a loss or deficiency of interneuron function using the purified or enriched population of immature interneuron progenitor cells are also disclosed.
1. An isolated or a purified preparation of human cortical immature interneuron precursor cells, wherein the human cortical immature interneuron precursor cells of the preparation comprise an exogenous recombinant nucleic acid molecule encoding a marker protein or a therapeutic agent, said recombinant nucleic acid molecule operably linked to at least one of a Lhx6 promoter region and a Lhx6 enhancer region.
2. The isolated or the purified preparation of claim 1 , wherein the human cortical immature interneuron precursor cells of the preparation comprise a genomic ally integrated bacterial artificial chromosome.
3. The isolated or the purified preparation of claim 1 , wherein the therapeutic agent is selected from the group consisting of neuropeptide Y, galanin, adenosine, and GABA.
4. The isolated or the purified preparation of claim 1 , wherein said recombinant nucleic acid molecule is genomically integrated into the cells.
