11. Effect of 3D Hydogel Scaffold Modulus and Topology on Human Bone Marrow Stromal Cell Fate
Topic: Biomaterials
Published: 9/1/2010
Authors: Kaushik Chatterjee, Sheng Lin-Gibson, Sapun Parekh, Nicole M. Moore, Marcus T Cicerone, marian f young, Carl George Simon Jr
Abstract: There is growing recognition that cells can sense and respond to the physical cues from their environment, such as stiffness, mechanical loading and topology. Physical properties of the matrix can direct cellular response and are critical in the desi ...

12. Effect of 3D Hydrogel Scaffold Stiffness on Human Bone Marrow Stromal Cell Differentiation
Topic: Biomaterials
Published: 11/1/2010
Authors: Carl George Simon Jr, Sapun Parekh, Marcus T Cicerone, Sheng Lin-Gibson, Kaushik Chatterjee, Marian F Young
Abstract: There is growing recognition cells can sense and respond to the mechanical properties of tissue scaffolds and that these interactions are critical in optimizing scaffold design [1-4]. Previous studies in planar 2D culture format have shown that human ...

13. 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 ...

14. Effect of Surface Chemistry on Stem Cell Response in 2-D vs. 3-D Cell Culture Niches
Topic: Biomaterials
Published: 4/19/2013
Authors: Sumona Sarkar, Carl George Simon Jr, Roberta I Lock, Joy P Dunkers
Abstract: To develop tissue engineered devices for regenerative medicine strategies, key scaffold properties for directing stem cell response must be identified. As focus shifts from 2-D to 3-D culture systems in an attempt to better recapitulate the na ...

15. Effect of offset values of solid freeform fabricated PCL/ß-TCP scaffolds on mechanical properties and cellular activities in bone tissue regeneration
Topic: Biomaterials
Published: 11/1/2012
Authors: Carl George Simon Jr, GeunHyung Kim, MyungGu Yo
Abstract: Microstructures of biomedical scaffolds can greatly affect cellular activities in tissue regeneration. In particular, scaffolds used in bone tissue regeneration should have several microstructural characteristics, including high porosity, appropriate ...

16. 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 ...

17. 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 ...

18. 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 ...

19. 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

20. 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 ...
