Engineering Bacterial Cellulose Scaffold And Its Biomimetic Composites For Bone And Cartilage Tissue Regeneration, Pelagie Marlene Favi May 2014

Engineering Bacterial Cellulose Scaffold And Its Biomimetic Composites For Bone And Cartilage Tissue Regeneration, Pelagie Marlene Favi

Doctoral Dissertations

A very promising approach to quickly and safely restore normal function to extensively damages and diseases bone and cartilage tissues is the regeneration of these injured tissues using an engineered support scaffold. This dissertation research focuses on the development and evaluation of native bacterial cellulose (BC) and chemically modified BCs as potential biomaterials for bone and cartilage regeneration using equine-derived bone marrow mesenchymal stem cells (EqMSCs).

The ability of native BC scaffold to maintain cell proliferation, viability, and in vitro differentiation of the seeded EqMSCs for application in bone and cartilage tissue engineering was studied. BC morphology was characterized using ...


Development Of A Moldable Composite Bone Graft Substitute Releasing Antibacterial And Osteogenic Drugs, Matthew E. Brown Jan 2014

Development Of A Moldable Composite Bone Graft Substitute Releasing Antibacterial And Osteogenic Drugs, Matthew E. Brown

Theses and Dissertations--Biomedical Engineering

Large infected bone defects (IBD) are very complicated to treat due to their high variability; they often require multiple procedures. Bone autografts are the gold standard for treatment but have several drawbacks, such as a need for a second surgery site, limited grafting material, and donor site morbidity. The objective of this research was to develop a moldable synthetic bone grafting material capable of releasing both antimicrobial and osteogenic drugs over a clinically relevant time course for the treatment of IBDs. Current treatment methods for large IBDs require two separate procedures to treat the bone defect and the infection.
