71. Nano-Apatitic Composite Scaffolds for Stem Cell Delivery and Bone Tissue Engineering
Topic: Biomaterials
Published: 4/15/2012
Authors: Hockin H. K. Xu, Carl George Simon Jr
Abstract: The need for bone defect repair and regeneration arises from trauma, disease, congenital deformity, and tumor resection. Bone fracture occurs to seven million people each year in the United States, and musculoskeletal conditions cost $215 billion ann ...

72. Nanofiber Scaffolds Induce Morphological Changes in hBMSCs Critical for Osteogenic Differentiation
Topic: Biomaterials
Published: 4/24/2011
Authors: Carl George Simon Jr, Girish Kumar, Christopher K. Tison
Abstract: Utilizing tissue scaffold architecture to induce stem cell differentiation is of tremendous importance to the regenerative medicine community. To this end, we have investigated the effect of nanofiber scaffold structure on primary human bone marrow s ...

73. Non-rigid and tough calcium phosphate cement scaffold seeded with umbilical cord stem cell for bone repair
Topic: Biomaterials
Published: 8/1/2013
Authors: Carl George Simon Jr, Hockin H. K. Xu, Michael D Weir, WahWah Thein-Han
Abstract: Human umbilical cord mesenchymal stem cells (hUCMSCs) are a promising alternative to bone marrow MSCs, which require invasive procedures to harvest. The objectives of this study were to develop a novel non-rigid and tough calcium phosphate cement (CP ...

74. Novel CaF2 Nanocomposite with High Strength and F Ion Release
Topic: Biomaterials
Published: 5/3/2010
Authors: Hockin D. Xu, Jennifer L. Moreau, Limin Sun, Laurence Chung Lung Chow
Abstract: Secondary caries and restoration fracture remain the two most common problems. The objectives of this study were to develop stress-bearing, fluoride-releasing nanocomposites. Novel CaF2 nanoparticles (56-nm) were synthesized via spray-drying and inco ...

75. OOF3D: An Image-Based Finite Element Solver for Materials Science
Topic: Biomaterials
Published: 3/28/2012
Authors: Valerie R. Coffman, Andrew Charles edmu Reid, Stephen A Langer, Gunay Dogan
Abstract: Recent advances in experimental techniques (micro CT scans, automated serial sectioning, electron back-scatter diffraction, synchrotron radiation x-rays) have made it possible to characterize the full, three dimensional structure of real materials. S ...

76. Optimization of Imaging Polymer Based Scaffolds Using X-Ray Microcomputed Tomography
Topic: Biomaterials
Published: 5/15/2012
Authors: David E, Morris, Melissa L Mather, Carl George Simon Jr, John A Crowe
Abstract: The performance of polymer based scaffolds used in regenerative medicine is linked to their structural properties and as such strategies for structural characterization of scaffolds have been developed. X-ray microscopic computed tomography (X-ray ...

77. Osteoblast Response to Protein Adsorption to 3D Polymer Scaffolds Through Pre-Ageing in Cell Medium
Topic: Biomaterials
Published: 4/24/2011
Authors: Carl George Simon Jr, Kaushik Chatterjee, Stevephen Hung
Abstract: Protein adsorption mediates biological responses to materials. When a biodegradable polymer scaffold is placed in aqueous, physiological medium, proteins adsorb onto the scaffold surface. The total amount, composition and structure of the adsorbed pr ...

78. Osteoblast Response to Serum Protein Adsorption in 3D Polymer Scaffolds
Topic: Biomaterials
Published: 5/1/2012
Authors: Carl George Simon Jr, Girish Kumar, Kaushik Chatterjee, Stevephen Hung
Abstract: Protein adsorption is known to direct biological response to biomaterials and is important in determining cellular response in tissue scaffolds. In this study we investigated the effect of adsorbed serum proteins on cell attachment and proliferation ...

79. Osteocyte Enhancement of Angiogenesis In Vitro
Topic: Biomaterials
Published: 2/14/2007
Authors: Erica Takai, Juan M. Taboas, Rocky Tuan, Steven D Hudson
Abstract: It is well known that an intimate relationship exists between vascularization and bone formation during development and fracture healing, where new bone formation is preceded by local vascularization. A recent rat exercise model has demonstrated that ...
