title: Establishing a 3D ex vivo culture system for investigations of bone metabolism and biomaterial interactions.
abstract: A 3D load-providing culture system is presented, which enables human cancellous bone explants to be studied ex vivo. Bone integrity and activity was demonstrated during 2 to 3 weeks of culture. Viable osteocytes and bone specific markers could be identified. Culture conditions were improved using a serum free medium containing TGF-beta3. Therefore this system gives the opportunity to study bone biology, hormonal effects as well as biomaterial interactions ex vivo prior to animal studies.
