11. Effect of 3D Scaffold Structure on Osteogenic Differentiation of Human Bone Marrow Stromal Cells
Topic: Biomaterials
Published: 4/24/2011
Authors: Carl George Simon Jr, Girish Kumar, Marian F Young
Abstract: Structural properties of polymeric scaffolds for tissue engineering play a key role in directing osteogenesis. These properties depend on the chemical nature and the fabrication process of biomaterial. There are many protocols for fabricating scaff ...

12. Effects of nanoparticle size and charge on interactions with self-assembled collagen
Topic: Biomaterials
Published: 3/1/2014
Authors: Dongbo Wang, Jing (Jing) Ye, Steven D Hudson, Keana C k Scott, Sheng Lin-Gibson
Abstract: Recent insights into bone formation have suggested that the critical first step to the biomineralization process is the integration of small (nanometer dimension) mineral clusters into collagen fibers. Such behavior is of intrinsic interest for the a ...

13. Effects of sample preparation on bacterial colonization of polymers
Topic: Biomaterials
Published: 10/19/2009
Authors: Diana N. Zeiger, Christopher M Stafford, Yajun Cheng, Stefan D Leigh, Sheng Lin-Gibson, Nancy J Lin
Abstract: Characterization of materials developed for medical usage frequently includes studies in which the materials are inoculated with bacteria in order to assess biofilm formation. Differences in the bacteria are considered to be due to the material alon ...

14. Electrochemical Study of Chitosan Films Deposited on Gold Electrodes
Topic: Biomaterials
Published: 7/28/2006
Authors: Rebecca A Zangmeister, J J Park, G W Rubloff, Michael J Tarlov
Abstract: We report the electrochemical characterization of chitosan films deposited on gold electrodes. Cyclic voltammetry was used to characterize the deposition and electroactivity of chitosan coated gold electrodes. Chitosan films were found to deposit a ...

15. Encapsulated Chondrocyte Response in a Pulsatile Flow Bioreactor
Topic: Biomaterials
Published: 1/1/2007
Authors: James Cooper, W Li, L A Bailey, Steven D Hudson, Sheng Lin-Gibson, Kristi S. Anseth, Rocky Tuan, N. R. Washburn

16. Evaluation of Polydimethylsiloxane Modification Methods for Cell Response
Topic: Biomaterials
Published: 2/20/2009
Authors: Lisa Pakstis, Alan Zheng, Theodore Vincent Vorburger, Joy P Dunkers, Timothy P Quinn, Marcus T Cicerone
Abstract: Many methods exist in the literature to modify surfaces with extracellular matrix (ECM) proteins prior to cell attachment. However, there are few studies that systematically compare surface characterization and cell response results among different m ...

17. FRACTURE OF TOOTH ENAMEL FROM INCIPIENT MICROSTRUCTURAL DEFECTS
Topic: Biomaterials
Published: 6/14/2010
Authors: H Chai, James J. Lee, Brian Ronald Lawn
Abstract: We present definitive evidence for crack growth from internal defects called 'tufts' in human enamel. Side walls of slices sawn from extracted human teeth are observed during loading to 'failure'. 'Longitudinal' and 'transverse' slices (parallel ...

18. Facile Fabrication of "Dual Click" One- and Two-Dimensional Orthogonal Peptide Concentration Gradients
Topic: Biomaterials
Published: 1/21/2013
Authors: Yanrui Ma, Jukuan Zheng, Emily F. Amond, Christopher M Stafford, Matthew L Becker
Abstract: Peptides, proteins and extracellular matrix act in concert to influence cellular function at the biotic-synthetic interface. However identifying the individual and synergistic contributions of the various combinations and concentration regimes is e ...

19. Fine-tuning of polymeric resins and their interfaces with amorphous calcium phosphate. A strategy for designing effective remineralizing dental composites
Topic: Biomaterials
Published: 9/29/2010
Authors: Joseph M Antonucci, Drago Skrtic
Abstract: For over a decade our group has been designing, preparing and evaluating bioactive, remineralizing composites based on amorphous calcium phosphate (ACP) fillers embedded in polymerized methacrylate resin matrices. In these studies a major focus has b ...

20. Freeform Fabricated Scaffolds with Roughened Struts that Enhance both Stem Cell Proliferation and Differentiation by Controlling Cell Shape
Topic: Biomaterials
Published: 3/1/2012
Authors: Girish Kumar, Carl George Simon Jr, Michael S. (Michael Stephan) Waters, Tanya M. Farooque, Marian F Young
Abstract: We demonstrate that imparting freeform fabricated (FFF) scaffolds with surface roughness on their struts enhances osteogenic differentiation of primary human bone marrow stromal cells (hBMSCs) by controlling cell shape. Previous work showed that hBM ...
