Available in PDF, EPUB and Kindle. Book excerpt: Bone defects are a prevalent problem in orthopedics and dentistry. Calcium phosphate-based coatings and nanocomposites offer unique solutions towards producing scaffolds with suitable physical, mechanical and biological properties for bone regeneration. We developed a novel method to synthesize hydroxyapatite (HA) particles with high aspect ratio using sol-gel chemistry and hydrothermal treatment. We obtained tunable pure-phase carbonated-HA in the form of micro/nanorods and nanowires (diameters 25-800 nm). To mimic the structure of bone, HA nanowires were homogenously mixed within poly( -caprolactone) (PCL) to produce nanocomposites with improved mechanical properties as determined by uniaxial tensile testing. Surface chemistry and topography of biomaterials play prominent roles in regulating cell adhesion and differentiation. Bone-like apatite coatings, produced by incubating materials in a simulated body fluid (SBF), improve the osteoconductivity of scaffold materials. However, few studies have controlled the surface topography of biomimetic HA. We assessed the effect of SBF ion concentration and soaking time on the surface properties of apatite coatings. Calcium phosphates such as carbonated-HA with similar chemical composition and stiffness were deposited onto PCL films. Characterization of these coatings revealed an increase in topographical complexity and surface roughness with increasing ion concentration of SBF and soaking time. To investigate their potential application in bone regeneration, we studied the influence of topography of biomimetic HA coatings on the behavior of osteoblasts and osteoclasts in vitro. Osteoblast attachment and differentiation were significantly greater iv when cultured on rougher HA surfaces (Ra 2̃ m) than on smoother topographies (Ra 1̃ m). In contrast, activity of tartrate-resistant acid phosphatase (an osteoclast marker) was greater on smoother than on rougher HA surfaces. Furthermore, osteoclastic resorption lacunae were found exclusively on smoother HA coatings. Inhibition of resorption on rougher HA surfaces was associated with disruption of filamentous actin sealing zones. In conclusion, HA coatings can be prepared with different topographies, which regulate responses of osteoblasts and osteoclasts. Thus, it may be possible to design HA-polymer composites and HA-coated polymers with physical, mechanical and biological properties suitable for tissue engineering. By modulating topography, rates of bone formation and biodegradation could be tailored for specific applications in orthopedics and dentistry.

Download or read book Bone Regeneration by Tuning the Drug Release from the Calcium Phosphate Scaffolds written by Kanupriya Khurana and published by . This book was released on 2018 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bone is among the most transplanted tissues for regeneration of bone defects, caused by trauma, age-related bone loss or bone infections. Due to their similar characteristics to the mineral phase of bone, calcium phosphates (CaPs) have raised a lot of interest. Some properties of CaPs, like biodegradability, biocompatibility, bioactivity and osteoconduction represent a great potential for this application. Among them, calcium phosphate cements (CPCs) have additional advantages like injectability and in situ hardening ability. Moreover, the possibility to tune the porosity of CaPs in general and of CPCs in particular, makes them suitable vehicles for local delivery of drugs. Loading CaPs with drugs allows conferring additional functionalities to the synthetic bone grafts, which is of great interest. The main aim of this thesis is to explore CaP bioceramics as vehicles for local delivery of drugs, covering both low temperature biomimetic ceramics, like calcium deficient hydroxyapatite (CDHA), and high temperature sintered ceramics, like beta tricalcium phosphate (ß-TCP), in the form of microporous and macroporous substrates. The physic-chemical nature of these bioceramics, their porosity and textural properties plays an essential role in their drug delivery properties. In order to be able to tailor the drug release kinetics of the bioceramics beyond their intrinsic properties, plasma polymerization has been investigated. Plasma is a particular state of a gas, electrically neutral, which can be employed in different applications. Although plasma polymerization has been widely studied for biomedical applications, its combination with bioceramics is rather unexplored. To select a suitable drug for bone regeneration, an extensive literature review was done on statins, and more particularly on simvastatin as a potential osteogenic and angiogenic promoter. This drug was evaluated within macroporous scaffolds of either CDHA or ß-TCP as drug delivery vehicles. The drug-loaded materials were plasma-coated with polycaprolactone: poly ethylene glycol (PCL:PEG) co-polymers. The coating covered the micro and nanopores of the CaPs surface and produced complex geometries presenting a nano and micro rough morphology which led to low wettability despite the hydrophilicity of the copolymer. Plasma coating with PCL-co-PEG on scaffolds loaded with simvastatin acid allowed delaying and modulating the drug release from the bone scaffolds depending on the thickness of the layer deposited, which, in turn depended on the initial specific surface area of the CaP. To further investigate the fundamentals of plasma polymerization on bioceramics, PEG-like polymer coatings of different thickness were deposited on microporous ß-TCP loaded with antibiotics. The rough ß-TCP surface was associated to strong hydrophobic surface properties, which nevertheless retained their suitable biological behavior with regard to human osteoblast cells. The microbiological activity of the antibiotics was preserved, and the coatings reduced the total amount of drug released as a function of the increasing plasma treatment time. In another approach, a statin that had never before been employed in combination with CaPs, Pitavastatin (PITA), was investigated as potentially osteogenic and angiogenic promoter through in vitro studies which revealed dose-dependent enhancement of mineralization and vascularization. The incorporation of PITA to the liquid phase of an injectable CDHA foam allowed obtaining injectable local drug delivery scaffolds, without altering their macroporosity or textural properties. The drug release kinetics was affected by the evolving microstructure of the setting of the macroporous cement. Overall the results obtained proved that PITA seems to be a suitable novel candidate to enhance the osteogenic potential of synthetic bone grafts and identified the required doses to obtain the desired biological effects.
