Additional Information
Statement
Reference

solo is expressed in mitotic cells in the posterior region of the germarium, but not in the anterior-most region of the germarium that contains stem cells and early cystoblasts.

(Yan and McKee, 2013)

solo localizes to spermatogonia but not somatic cyst cells.
