Inhibin immunoreactivity in gonadal and non-gonadal tumors [PDF]
The Journal of Steroid Biochemistry and Molecular Biology, 1990 Inhibin immunoreactivity was estimated in a number of gonadal and non-gonadal tumors. Dog Sertoli cell tumors and human granulosa cell and Leydig cell tumors contained high concentrations of inhibin-like material. Levels, comparable with those in normal testes and ovaries were detected in human testicular non-seminomas and in ovarian cystadenomas ...
