In addition, Gαi and patJ were undetectable in both FSCs and prefollicle cells, but became detectable in more mature follicle cells (Fig S1D–E), whereas partner of numb, brain tumor, and prospero appeared to be diffuse in or completely absent from FSCs and all follicle cells in the germarium (Fig S1F–H). This evidence concerns the gene PATJ and brain neoplasm.
