    摘要： The present invention relates to culture systems comprising differentiated stem cells, that may be used for identifying agents useful in treating degenerative nervous system disorders and are suitable for high-throughput screening applications. It is based, at least in part, on the discovery that co-cultures of (i) astrocytes expressing a mutated SODI gene and (ii) stem-cell derived motor neurons manifested cell death via a Bax-dependent mechanism, and modeled motor neuron death in amyotrophic lateral sclerosis.

    摘要： Disclosed are methods for generating a neuron expressing Hoxc8 transcription factor or a caudal motor neuron comprising culturing an embryonic stem cell in a composition which is essentially free of retinoids and comprises an isotonic salt solution, so as to generate the neuron which expresses Hoxc8 transcription factor or the caudal motor neuron. Disclosed are also methods for generating a caudal brachial motor neuron, a thoracic motor neuron, or a lumbar motor neuron from an embryonic stem cell in a composition essentially free of retinoids and comprising ADFNK medium, an amount of FGF-2, or Gdf11 respectively. Disclosed are also methods of transplanting a motor neuron into a subject comprising generating the motor neuron and transplanting the motor neuron into the subject. Disclosed is also a population of motor neuron cells enriched for motor neuron cells expressing Foxp1 and expressing a gene associated with Spinal Muscular Atrophy (SMA) or Amyotrophic Lateral Sclerosis (ALS).
