Recent advances in tissue-engineered cartilage open the door to new clinical treatments of joint lesions. Common to all therapies with in-vitro engineered autografts is the need for optimal fit of the construct, to allow screwless implantation and optimal integration into the live joint. Computer assisted surgery techniques are prime candidates to ensure the required accuracy while at the same time...
Collagen and apatite were co-precipitated as a composite coating on poly L-lactic acid (PLLA) in an accelerated biomimetic process. The coating formed on PLLA films after 24 hours incubation was characterized. Saos-2 osteoblast-like cells were used to evaluate the cell seeding on this biomimetic composite coating. It was shown that cell seeding on PLLA films with the composite coating was greatly...
Engineering functional three-dimensional (3-D) tissue constructs for the replacement and/or repair of damaged native tissues using cells and scaffolds is one of the ultimate goals of tissue engineering. In this study, non-woven fibrous scaffolds were electrospun from the synthetic biodegradable polymer poly(lactic-co-glycolic acid) (PLGA) and natural proteins, gelatin (denatured collagen) and elastin...
Understanding the ultra-structural response of cells to the cryopreservation process is important for designing cryopreservation strategies for cells and tissues. Cell-cell interaction and cell-scaffold interactions alter cryopreservation response and, in turn, the cellular structures involved in adhesion and intercellular contact are targets of cryopreservation-induced damage. Immuno-fluorescence...
A bioactive and biodegradable composite containing hydroxyapatite (HA) and polyhydroxybutyrate (PHB) was developed for bone tissue repair. A manufacturing process, which consisted of compounding, pelletising, drying, and injection moulding, was established for producing the composite. The HA/PHB composite containing 10, 20, 30 and 40% by volume of particulate HA was successfully made. The distribution...
