Additional Information
Statement
Reference

ScerGAL4GSG3687-1 drives mifepristone-inducible expression primarily in neurons and glial cells. Moderate expression is observed in the ventral nerve cord in 5-6 dorsal midline cells perhemisegment, including A1-7 dorsal motor neurons. Ventral nerve cord expression is also observed in 10+ lateral cells, 20+ ventral cells, and an unpaired ventral midline cell per hemisegment; these cells are likely mix of neurons and glial cells. Expression is observed in neuons and glial cells in the mushroom body, and scattered in the brain. Weak expression is observed in type Is and Ib boutons of most neuromuscular junctions. Eexpression is observed in glial cells in the both central and peripheral nervous systems. Patchy epidermal expression is also observed. Moderate uninduced expression is observed in a subset of CNS cells.
