31. Gradient Nanofiber Scaffold Libraries for Screening Cell Response to Poly(e-caprolactone)-Calcium Phosphate Composites
Topic: Biomaterials
Published: 3/1/2013
Authors: Carl George Simon Jr, Limin Sun, Laurence Chung Lung Chow, William Miles, Christopher K. Tison, Kaushik Chatterjee, Marian F Young, Vinoy Thomas, Murugan Ramalingam
Abstract: A 2-spinnerette approach has been developed for fabricating nanofiber scaffold gradients for use as 1) scaffold libraries for screening the effect of nanofiber properties on cell response and 2) templates for generating graded tissue interfaces. Alt ...

32. Hybrid Cell Adhesive Material for Instant Dielectrophoretic Cell Trapping and Long Term Cell Function Assessment
Topic: Biomaterials
Published: 8/16/2011
Authors: Darwin R Reyes-Hernandez, Jennifer S. Hong, John T Elliott, Michael Gaitan
Abstract: We present the development and evaluation of an engineered hybrid cell adhesive surface for instant dielectrophoretic trapping and patterning of cells in a microfluidic device. This work demonstrates that a hybrid cell adhesive material (hCAM) prepar ...

33. Identification of a Highly-Specific Hydroxyapatite-Binding Peptide Using Phage Display
Topic: Biomaterials
Published: 5/19/2008
Authors: Matthew Becker, Marc Roy, Scott K. Stanley, Eric J. Amis
Abstract: Using a phage display approach we have identified a peptide sequence SVSVGMKPSPRP that selectively recognizes HA over amorphous calcium phosphate. Exploitation of the recognition properties of such peptidic species to specific polymorphs deposited d ...

34. Improved Contact X-Ray Microradiographic Method to Measure Mineral Density of Hard Dental Tissues
Topic: Biomaterials
Published: 12/12/2009
Authors: Burton Deedrick Schmuck, Clifton M. Carey
Abstract: Contact X-ray microradiography is the current gold standard for measuring mineral densities of partially demineralized tooth specimens. The X-ray sensitive film specified in the last J Res NIST publication on the subject is no longer commercially av ...

35. Maturation Stage Dependent Interaction of Mature Osteoblasts and Osteoprogenitor Cells with Microvascular Endothelial Cells
Topic: Biomaterials
Published: 2/14/2007
Authors: Erica Takai, Rocky Tuan, Steven D Hudson
Abstract: Angiogenesis is essential to the development, maintenance, and repair of bone tissue, as well as the survival of engineered tissues. Also, since osteoblasts (OB) are found in close proximity to endothelial cells in areas of new bone formation, it ha ...

36. Measuring Organelle Shape in 3D in Stem Cells Cultured on Nanofiber Scaffolds
Topic: Biomaterials
Published: 4/19/2014
Authors: Carl George Simon Jr, Peter Bajcsy, Wojtek J Tutak, Jyotsnendu (Jyotsnendu) Giri
Abstract: Previous work has demonstrated that culture of osteoprogenitor cells on nanofiber scaffolds can potentiate osteogenic differentiation [1-4]. Culture of cells in nanofiber scaffolds causes changes to cell morphology, suggesting that morphological ...

37. Measuring Stem Cell Dimensionality in Tissue Scaffolds
Topic: Biomaterials
Published: 4/1/2014
Authors: Carl George Simon Jr, Sapun Parekh, Christopher K. Tison, Girish Kumar, Tanya M. Farooque, Charles H Camp
Abstract: Many 3D scaffold systems have evolved for tissue engineering, drug screening and in vitro tissue models. However, it is not clear which scaffolds provide a 3D cell niche and there is no clear way to measure cell niche dimensionality. Advances in 3D ...

38. Modulus-Driven Differentiation of Marrow Stromal Cells in 3D Is Independent of Cytoskeletal Integrity
Topic: Biomaterials
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 ...

39. Morphological Changes Driven by Nanofibrous Scaffolds Induce Marrow Stromal Cell Osteogenesis
Topic: Biomaterials
Published: 10/11/2011
Authors: Carl George Simon Jr, Kaushik Chatterjee, Christopher K. Tison, Girish Kumar, Patrick S Pine, Marc L Salit, Jennifer H McDaniel, Marian F Young
Abstract: Cells are sensitive to tissue scaffold architecture and these cell-material interactions drive cell functions critical in tissue regeneration. Results presented here demonstrate that nanofiber scaffolds force primary human bone marrow stromal cells ...

40. NIST Micronutrients Measurement Quality Assurance Program Winter 2011 Comparability Studies: Results for Round Robin LXIX Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 34 Ascorbic Acid in Human Serum
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7880-3
Topic: Biomaterials
Published: 8/2/2013
Authors: David Lee Duewer, Jeanice M Brown Thomas
Abstract: The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report desc ...
