Bewertung von neuartigen Biomaterialien zum Zweck der Knochenrekonstruktion und regeneration. In-vitro-Versuche mit Mono- und Kokulturen von Osteoblasten und Endothelzellen

Many different types of bone substitute biomaterials are being developed for different applications in the body. The current dogma is that if osteoblasts and endothelial cells grow and exhibit normal cell functions on these materials in vitro as single cultures or in co-cultures, then the biomaterials are suitable for implantation for bone reconstruction and regeneration. Generally, only in vivo animal studies will prove whether this is the case. However, in vitro studies offer a good pre-screening and selection basis to evaluate the biocompatibility of novel biomaterials prior to animal studies. Multicell type co-culture systems hold a great promise for the future.
