Order versus Disorder: in vivo bone formation within osteoconductive scaffolds
In modern biomaterial design the generation of an environment mimicking some of the extracellular matrix features is envisaged to support molecular cross-talk between cells and scaffolds during tissue formation/remodeling. In bone substitutes chemical biomimesis has been particularly exploited; conversely, the relevance of pre-determined scaffold architecture for regenerated bone outputs is sti...
متن کاملNovel Resorbable and Osteoconductive Calcium Silicophosphate Scaffold Induced Bone Formation
This aim of this research was to develop a novel ceramic scaffold to evaluate the response of bone after ceramic implantation in New Zealand (NZ) rabbits. Ceramics were prepared by the polymer replication method and inserted into NZ rabbits. Macroporous scaffolds with interconnected round-shaped pores (0.5-1.5 mm = were prepared). The scaffold acted as a physical support where cells with osteob...
متن کاملEffects of Cell-Attachment and Extracellular Matrix on Bone Formation In Vivo in Collagen-Hydroxyapatite Scaffolds
Cell-based tissue engineering can be used to replace missing or damaged bone, but the optimal methods for delivering therapeutic cells to a bony defect have not yet been established. Using transgenic reporter cells as a donor source, two different collagen-hydroxyapatite (HA) scaffolds, and a critical-size calvarial defect model, we investigated the effect of a cell-attachment period prior to i...
متن کاملIn-Vivo Study of Bioceramics in Order to Make Bone Prosthes
Purpose: There are a lot of experiences about using bone-like materials in order to replace bone defects, especially those which are caused by cancer therapy. The most suitable materials for this purpose are bioceramics. The investigations have been shown that bioceramics are able to induce proliferation of osteoblast as well as bone matrix synthesis in - vivo.The aim of the present study is to...
متن کاملInfluence of osteogenic stimulation and VEGF treatment on in vivo bone formation in hMSC-seeded cancellous bone scaffolds
BACKGROUND Tissue engineering approaches for reconstruction of large bone defects are still technically immature, especially in regard to sufficient blood supply. Therefore, the aim of the present study was to investigate the influence of osteogenic stimulation and treatment with VEGF on new bone formation and neovascularization in hMSC-loaded cancellous bone scaffolds in vivo. METHODS Cubic ...
