Induction of seminal vesicle morphogenesis from dog epididymal epithelium.
A number of carnivores, including the dog, do not have seminal vesicles (SVs). They have been induced experimentally by heterotypic recombination of adult dog epididymal epithelium with mesenchyme of neonatal rat SV and allowed to grow for 4 weeks under the renal capsule of male athymic nude mice. The induced SVs bore a striking similarity to rat SV both histologically and ultrastructurally. However, they secreted proteins which were different from those in the rat SV and reacted negatively to antibodies specific to rat SV secretory proteins and dog prostate secretory proteins. The results strongly suggested that the glands induced from dog epididymal epithelium were likely to be "dog" SVs.
