ScerGAL4cb10 drives expression in the embryonic CNS and lymph glands, in the larval central nervous system including the brain, and in all imaginal discs. During oogenesis, ScerGAL4cb10 drives expression in oocyte associated follicle cells at stages S10-14, in oocytes at stage S10, in terminal filaments and/or female germline stem cells, in aeropyles, and in dorsal appendage forming follicle cells.
