PROTOTYPING 3D-PRINTED BIOCERAMIC SCAFFOLDS WITH ADIPOSE-DERIVED STEM CELLS: THE NEXT GENERATION IN BONE INDUCTIVE BIOCERAMICS

Since the development of biomimetic and ceramic bone reconstructive in the early 1970, these specialised bioreactors intended for bone or cartilage regeneration have come a long way in trying to design an alternative procedure other than autogenous bone grafting. However, all known biomaterials still fall short of inducing substantial bone formation in vitro or in vivo, especially when treating large bony defects. As such there is a necessity to develop novel bone-reconstructive biomaterials that can more appropriately be utilised and can induce substantial more bone formation than current scaffolds. Using the rapid prototyping technique (Friedrich-Baur BioMed Center, Bayreuth, Germany) to develop new and improved hydroxyapatite/β-tricalcium phosphate devices, which can be predesigned to any outer shape with controlled pore structure and exhibit a unique intrinsic porosity <150µm due to the 3D-printing process to fit any skeletal bone loss site, the aim of our laboratories was to test the osteoinductive c...
