With Testis Grafts from Neonatal Pigs and Goats, Mice Become First Animals to Produce Other Species’ Sperm
Wednesday, August 14, 2002
PHILADELPHIA – With pinhead-sized grafts of testicular tissue from newborn mammals, scientists at the University of Pennsylvania have induced mice to produce fully functional sperm from evolutionarily distant species. The result has important implications for preserving the germ lines of critically endangered species as well as prized livestock.
Penn's School of Veterinary Medicine is one of the world's premier veterinary schools. Founded in 1884, the School was built on the concept of Many Species, One Medicine. The birthplace of veterinary specialties, the School serves a distinctly diverse array of animal patients, from pets to horses to farm animals at our two campuses. In Philadelphia, on Penn's campus, are the Matthew J. Ryan Veterinary Hospital for companion animals, as well as classrooms, laboratories and the School's administrative offices. The large-animal facility, New Bolton Center, in Kennett Square, Pa., encompasses hospital facilities for the care of horses and food animals as well as diagnostic laboratories serving the agriculture industry. The School has successfully integrated scholarship and scientific discovery with all aspects of veterinary medical education.
