Large-scale Time-lapse Microscopy of Oct4 Expression in Human Embryonic Stem Cell Colonies

May 22, 2016
Author(s)
Kiran Bhadriraju, Michael Halter, Julien M. Amelot, Peter Bajcsy, Joe Chalfoun, Antoine Vandecreme, Barbara Mallon, Kye-yoon Park, John T. Elliott, Subhash Sista, Anne L. Plant
Identification of critical characteristics of therapeutically active cells, and quantification of those characteristics, are essential for assuring consistency and potency of cell therapy products. We have developed image analysis and visualization

Survey Statistics of Automated Segmentations Applied to Optical Imaging of Mammalian Cells

January 8, 2016
Author(s)
Peter Bajcsy, Antonio Cardone, Joe Chalfoun, Michael W. Halter, Derek Juba, Marcin Kociolek, Michael P. Majurski, Adele P. Peskin, Carl G. Simon Jr., Mylene H. Simon, Antoine Vandecreme, Anne L. Plant, Mary C. Brady
The goal of this survey paper is to overview cellular measurements using optical microscopy imaging followed by automated image segmentation. The cellular measurements of primary interest are taken from mammalian cells and their components. They are

High Resolution Surface Plasmon Resonance Imaging for Single Cells

December 1, 2014
Author(s)
Alexander W. Peterson, Michael W. Halter, Alessandro Tona, Anne L. Plant
Background Surface plasmon resonance imaging (SPRI) is a label-free technique that can image refractive index changes at an interface. We have previously shown that SPRI can be used to study the dynamics of cell-substratum interactions. However

Automated Ranking of Stem Cell Colonies by Translating Biological Rules to Computational Models

September 20, 2014
Author(s)
Adele P. Peskin, Steven P. Lund, YaShian Li-Baboud, Michael W. Halter, Anne L. Plant, Peter Bajcsy
This paper addresses the problem of automating an image ranking process for stem cell colonies. We automate the manual process in a novel way: instead of fitting off-the-shelf image features and colony ranks to prediction models, we define a new feature

Assuring Confidence in Measurements in Biomedical Research

August 28, 2014
Author(s)
Anne L. Plant, Laurie E. Locascio, Willie E. May, Patrick D. Gallagher
‘Irreproducibility’ is a symptom of a broad challenge in measurement that needs to be addressed. Establishing a robust measurement process that will lead to greater confidence in biomedical research results will require a concerted effort from experts.

Performance Benchmarking and Intensity Calibration of a Widefield Fluorescence Microscope Using Fluorescent Glass

August 11, 2014
Author(s)
Michael W. Halter, Elianna Bier, Paul C. DeRose, Gregory A. Cooksey, Steven J. Choquette, Anne L. Plant, John T. Elliott
Widefield fluorescence microscopy is a highly used tool for visually assessing biological samples and for quantifying cell responses. Despite its widespread use in high content analysis and other screening applications, few published methods exist for

Frictional properties of native and functionalized type I collagen thin films

October 2, 2013
Author(s)
Koo-hyun Chung, Antony Chen, Christopher Anderton, Kiran Bhadriraju, Anne L. Plant, Brian G. Bush, Robert F. Cook, Frank W. DelRio
Frictional properties of native and fibronectin (FN)-functionalized type I collagen (COL) thin films were studied via atomic force microscopy. The COL lateral contact stiffness was dependent only on the hydration state, indicating that shear deformation

Measurement Uncertainty in Cell Image Segmentation Data Analysis

August 13, 2013
Author(s)
Jin Chu Wu, Michael W. Halter, Raghu N. Kacker, John T. Elliott, Anne L. Plant
Cell image segmentation is a part of quantitative studies regarding cell movement and cell behavior, and it plays a critical role in molecular biology and cellular biochemistry. Therefore, it is fundamentally important to evaluate the performance levels of

Controlled Chemistry for Studying Combined Effects of Extracellular Matrix Proteins

April 22, 2013
Author(s)
Antony K. Chen, Frank W. DelRio, Alexander W. Peterson, Koo-Hyun Chung, Kiran Bhadriraju, Anne L. Plant
The extracellular matrix (ECM) consists of a complex mixture of biochemical and physical stimuli that together regulate cell behavior. Previously we showed that films composed of Type I collagen fibrils induce reproducible and physiologically relevant cell

Review: Biological Imaging Software Tools

August 29, 2012
Author(s)
Anne L. Plant, Kevin Eliceiri, Anne Carpenter
Few technologies are more widespread in modern biological laboratories than imaging by microscopy. Advancements in optical technologies and instrumentation over the past twenty years have led to massive improvements in the resolution, specificity

Quantitative Methods to Characterize Cell Lines: Comparison of Cells from Marine and Terrestrial Mammals.

July 28, 2012
Author(s)
Tighe Spurlin, John T. Elliott, Michael W. Halter, Kiran Bhadriraju, Alessandro Tona, Anne L. Plant, Annalaura Mancia, Bobby L. Middlebrooks, Gregory W. Warr
Descriptive terms are often used to characterize cells in culture, but the use of nonquantitative and poorly defined terms can lead to ambiguities when comparing data from different laboratories. Although recently there has been a good deal of interest in
