91. Combinatorial Screening of Osteoblast Response to 3D Nano-Composite Tissue Scaffolds Using Gradients and Arrays
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr, Kaushik Chatterjee, Limin Sun, Laurence Chung Lung Chow, Marian F Young
Abstract: Current methods for combinatorial and high-throughput (CHT) screening of cell-material interactions utilize a two-dimensional (2D) format where cells are presented on flat materials surfaces [1]. However, cell response in 3D scaffolds is more represe ...

92. Effect of 3D Scaffold Structure on Osteogenic Differentiation of Human Bone Marrow Stromal Cells
Topic: Bioscience & Health
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 ...

93. NIST Reference Material Scaffolds Characterized for Cell Response
Topic: Bioscience & Health
Published: 4/24/2011
Authors: Carl George Simon Jr, Jeff M Coles
Abstract: Reference scaffolds characterized for cell response are being developed for use as a standard for biological characterization of new scaffolds. The need for reference scaffolds to serve as a calibration standard between labs has been identified as c ...

94. Nanofiber Scaffolds Induce Morphological Changes in hBMSCs Critical for Osteogenic Differentiation
Topic: Bioscience & Health
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 ...

95. Osteoblast Response to Protein Adsorption to 3D Polymer Scaffolds Through Pre-Ageing in Cell Medium
Topic: Bioscience & Health
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 ...

96. Flip Chip Lamination to electrically contact organic single crystals on flexible substrates
Topic: Bioscience & Health
Published: 4/20/2011
Authors: Oana Jurchescu, Brad Conrad, Christina Ann Hacker, David J Gundlach, Curt A Richter
Abstract: The fabrication of top metal contacts for organic electronics represents a challenge and has important consequences for electrical properties of such systems. We report a low cost and non-destructive printing process, Flip Chip Lamination (FCL), to f ...

97. Differences in Polydimethylsiloxane Modification Methods Affect Laminin Deposition and Smooth Muscle Cell Proliferation
Topic: Bioscience & Health
Published: 4/13/2011
Authors: Joy P Dunkers, Hae-Jeong Lee, Marvi Matos, Lisa Pakstis, Juan M. Taboas, Steven D Hudson, Marcus T Cicerone
Abstract: When culturing cells on flexible surfaces, it is important to consider extracellular matrix treatments that will remain on the surface under mechanical strain. Here we investigate differences in laminin surfaces that were deposited on oxidized PDMS ...

98. Modulus-Driven Differentiation of Marrow Stromal Cells in 3D Is Independent of Cytoskeletal Integrity
Topic: Bioscience & Health
Published: 4/11/2011
Authors: Carl George Simon Jr, Kaushik Chatterjee, Sapun Parekh, Sheng Lin-Gibson, Nicole M. Moore, Marcus T Cicerone, Marian F Young
Abstract: Cell functions such as proliferation, migration, and differentiation are key physiological processes that are influenced by the physiochemical extracellular environment. We report on the effect of three-dimensional (3D) scaffold modulus on human bon ...

99. Recent Advances in Electrochemical Glyco-biosensing
Topic: Bioscience & Health
Published: 4/8/2011
Authors: Rebecca A Zangmeister, Germarie Sanchez-Pomales
Abstract: Biosensors based on electrochemical transduction mechanisms have recently made advances into the field of glycan analysis. These glyco-biosensor assays offer simple, rapid, sensitive and economical approaches to the measurement need for rapid glycan ...

100. Live, video-rate super-resolution microscopy using structured illumination and rapid GPU-based parallel processing
Topic: Bioscience & Health
Published: 3/9/2011
Authors: Jonathan A. Lefman, Keana C k Scott, Javed Khan, Stephan J Stranick
Abstract: Structured illumination fluorescence microscopy is a powerful super resolution method that is capable of achieving a resolution below 100 nm. Each super-resolution image is computationally constructed from a set of differentially illuminated images. ...
