Biological characteristics of the peptides α and β isolated from bovine seminal plasma

Secretion of inhibin-like material by rat ventral prostate epithelial cells in culture

Monolayer cultures of epithelial as well as stromal components of the rat ventral prostate were established, taking advantage of differences in the requirement of sera supplementation and also in the temporal span for attachment. These monolayers were characterized and used to identify the cellular source of prostatic inhibin. The spent medium obtained from epithelial cell monolayer alone had significant inhibin-like activity.

Further studies on the synthesis and secretion of inhibin-like material by rat ventral prostate explants in vitro

To authenticate further the testicular androgen independent status of synthesis and secretion of inhibin-like material by the rat ventral prostate, explants of this organ were maintained for a period of 6 days in vitro, altering the kind of medium used for culture. The various spent media had significant inhibin-like activity despite the absence of sera supplement in some cases.
