Quantitative Analysis of a Candidate Porosity Reference Scaffold: Type 1

January 1, 2005

Author(s)

Joy P. Dunkers, John A. Tesk, David Dean, M Cooke, Richard Ketcham, Marcus T. Cicerone

Permeability of Polymeric Scaffolds With Defined Pore Micro-Architecture and Interconnectivity Fabricated by Solid Free-Form Microprinting

November 7, 2004

Author(s)

K W. Lee, E Jabbari, L L. Lu, B L. Currier, Joy Dunkers, Martin Chiang, John A. Tesk, Marcus T. Cicerone, M J. Yaszemski

The hydraulic permeability of was measured as a function of interconnectivity of the pores. The hydraulic permeability of porous scaffolds for tissue engineering of bone was measured as interconnectivity of the pores was changed from 100 % to 70 %. The

DEVELOPING METROLOGY FOR TISSUE ENGINEERING: COLLINEAR OPTICAL COHERENCE AND CONFOCAL FLUORESCENCE MICROSCOPIES

May 1, 2004

Author(s)

Joy P. Dunkers, Marcus T. Cicerone, James Cooper, Forrest A. Landis, N Washburn

We present a novel application of optical coherence microscopy (OCM) by combining it with confocal fluorescence microscopy (CFM) to gather simultaneous structural and functional information on tissue engineered medical products (TEMPs) in a registered

Optical Coherence Microscopy for in-situ Monitoring of Cell Growth in Scaffold Constructs

May 1, 2004

Author(s)

Marcus T. Cicerone, Joy Dunkers, N. R. Washburn, Forrest A. Landis, James A. Cooper

Tissue scaffold morphological properties are determined and correlated with osteoblast proliferation and ingrowth. Scaffold pore size and connectivity were characterized with x-ray tomography. Cell proliferation and ingrowth were measured with confocal

3d, Quantitative Image Analysis Of Poly(e-caprolactone) Scaffolds With Bicontinuous Morphology

April 27, 2004

Author(s)

Joy P. Dunkers, Forrest A. Landis, K Niihara, Hiropshi Jinai

It has been shown that scaffold microstructure impacts cell response.1 Determining the relationship between scaffold structure and cellular response facilitates scaffold design. Some descriptors of scaffold morphology thought to be influential are pore

A Test Method for Determining the Fiber and Void Contents of Carbon/Glass Hybrid Composites

March 1, 2004

Author(s)

Walter G. McDonough, Donald L. Hunston, Joy P. Dunkers, Kathleen M. Flynn

Hybrid composites are increasingly being used in infrastructure, oil recovery, and aerospace applications. These hybrids use two different fibers to reinforce the resin, thereby gaining some of the advantageous properties of both fibers. Typically carbon

Towards In-Situ Monitoring of Cell Growth in Tissue Engineering Scaffolds: High Resolution Optical Techniques

January 12, 2004

Author(s)

Marcus T. Cicerone, Joy P. Dunkers, N Washburn

Inability to obtain cellular-level information about progress of cell growth in tissue-engineering (TE) scaffolds is a pervasive problem. We demonstrate that a confocal microscope with two collinear contrast mechanisms, optical coherence, and fluorescence

Interaction Between Matrix Cracks in E-Glass/Epoxy 2 Dimensional Multi-Fiber Array Model Composites

November 15, 2003

Author(s)

Gale A. Holmes, Walter G. McDonough, Joy P. Dunkers, Charles C. Han

The interaction between fiber breaks in an E-Glass/Epoxy 2-D multifiber array that form matrix cracks during fiber fracture is presented. In contrast to the theoretical predictions of Hedgepeth and van Dyke (1967) the failure sites in fibers adjacent to a

Collinear Optical Coherence Microscopy and Confocal Fluorescence Microscopies for Tissue Engineering

November 1, 2003

Author(s)

Joy P. Dunkers, Marcus T. Cicerone, N Washburn

Tissue engineered medical products (TEMPs) often consist of a three-dimensional synthetic scaffold that provides form and foundation for the cells as they produce the tissue of interest. Successful TEMPs will allow cell infiltration, and foster

A New Metrology for Tissue Engineering: Collinear Optical Coherence and Confocal Fluorescence Microscopies

January 1, 2003

Collinear Optical Coherence and Confocal Fluorescence Microscopies for Tissue Engineering

January 1, 2003

Author(s)

Joy P. Dunkers, Marcus T. Cicerone, N. R. Washburn

We have combined confocal optical coherence (OCM) and confocal fluorescence (CFM) microscopies to gather simultaneous structural and functional information on tissue engineered products in a registered fashion. In this work, we present the design and
