- Gsdf is predominantly expressed in the testis of protogynous wrasse and is mainly localized to the supporting cells surrounding the spermatogonia.
- Only slight expression of gsdf was observed in most of the supporting cells in the neighboring ovarian oogonia.
- Strong expression of gsdf appeared in the supporting cells surrounding the gonial germ cells, which are the originators of spermatogenic cells in the ovary, during sex change induced by aromatase inhibition.
- These results suggest that gsdf is involved in the proliferation of spermatogonia and subsequent spermatogenesis in the early stages of sex change.
