(p. 1561, published online 20 May) now identify germline stem cells in the ovary of the teleost fish medaka. The stem cells are found as clusters of germ cells (termed germinal cradles) in a cord-like structure that expresses sox9, a gene critical for testis formation in mammals. The cords are buried within the ovary …
