Zusammenfassung:Bone homeostasis is a dynamic process involving a myriad of cells and substrates modulated by regulatory signals such as hormones, growth and differentiating factors. When this environment is damaged, the regenerative sequalae follows a programmed pattern, and the capacity for successful recovery is often dependent on the extent of the injury. Many bony deficits that are excessively traumatic will not result in complete recovery and require therapeutic intervention(s) such as autografting or grafting from banked bone. However, for numerous reasons, an unacceptably high rate of failure is associated with these conventional therapies. Thus, alternative approaches are under investigation. A class of osteogenic regulatory molecules, the bone morphogenetic proteins (BMPs), have been isolated, cloned and characterized as potent supplements to augment bone regeneration. Optimizing a therapeutic application for BMPs may be dependent upon localized sustained release which in kind relies on a safe and well characterized carrier system. This review will discuss the current status of BMPs in bone regeneration and specifically will present the potential for a clinical therapeutic role of recombinant human BMP-2 sustained release carrier systems.
