Additional Information
Statement
Reference

ScerGAL4l(2)GSG317-GSG317 drives mifepristone-inducible expression primarily in a subset of neurons and glial cells. Weak expression is obseved in ~5 lateral and ~5 ventral cells/hemisegment in the ventral nerve cord. Expression is observed in intersegmental processes in central, medial, and lateral longitudinal tracts, and a ventral lateral longitudinal axon tract (likely FasII VL axon tract). Strong expression is observed in CNS surface glia over the ventral nerve cord, but not over the brain.
