Company: Q Therapeutics
Drug Type: Stem Cell Therapy
Conditions: ALS, transverse myelitis, multiple scleorsis, spinal cord injury
Mechanism Type: Neuroprotection
Mechanism: Q-cells are purified human glial-restricted progenitors derived from human fetal neural tissue. In rats overexpressing mutant superoxide dismutase (SOD1), transplanted glial-restricted precursors prolong lifespan, reduce microgliosis, improve motor neuron survival and attenuate decline in motor and respiratory function. In SOD1 mice, transplantation did not attenuate motor neuron death or improve survival, however, the glial-restricted progenitors survived and differentiated into astrocytes in the spinal cord.
