Probing Pluripotency Gene Regulatory Networks with Live Cell Imaging

June 30, 2020
Author(s)
Anne L. Plant, Michael W. Halter, Jeffrey R. Stinson
Although live cell imaging has not been often used in the study of gene regulatory networks, it is a method that uniquely enables the measurement of dynamic events in single cells. Dynamical information about network components and their interactions is

A MULTIDIMENSIONAL LANDSCAPE MODEL FOR DETERMINING CELLULAR NETWORK THERMODYNAMICS

March 11, 2020
Author(s)
Joseph B. Hubbard, Michael W. Halter, Anne L. Plant
The distribution of phenotypic responses within an isogenic population of cells reflects the thermodynamics of a stationary state that results from coordinated intracellular reactions. The distribution of phenotypes is the result of both deterministic and

The high-content interrogation of single cells with platforms optimized for the multiparameter characterization of cells in liquid and solid biopsy samples can enable characterization of heterogeneous populations of cells ex vivo. Doing so will advance the

How measurement science can improve confidence in research results

April 23, 2018
Author(s)
Anne L. Plant, Chandler A. Becker, Robert J. Hanisch, Ronald F. Boisvert, Antonio M. Possolo, John T. Elliott
The concepts and methods of measurement science can help provide clarity in the definition of reproducibility and its role in the scientific process. The qualities of rigorous research include reproducibility as one component, but there are other important

A novel measure and significance testing in data analysis of cell image segmentation

April 20, 2017
Author(s)
Jin Chu Wu, Michael W. Halter, Raghu N. Kacker, John T. Elliott, Anne L. Plant
Background: Cell image segmentation (CIS) is an essential part of quantitative imaging of biological cells. Designing a performance measure and conducting significance testing are critical for evaluating and comparing the CIS algorithms for image-based

Surface plasmon resonance microscopy: achieving a quantitative optical response

September 8, 2016
Author(s)
Alexander W. Peterson, Michael W. Halter, Anne L. Plant, John T. Elliott
Surface plasmon resonance imaging (SPRI) allows real-time label-free imaging based on index of refraction, and changes in index of refraction at an interface. SPRI can be carried out on a microscope by launching light into a sample, and collecting

Standards for cell line authentication and beyond

June 14, 2016
Author(s)
Jamie L. Almeida, Kenneth D. Cole, Anne L. Plant
Different genomic technologies have been applied to cell line authentication, but only one method (short tandem repeat profiling) has been the subject of a comprehensive standard (ASN-0002). Here we discuss the power of this document, and why standards

Strategies for Achieving Measurement Assurance for Cell Therapy Products

June 1, 2016
Author(s)
Carl G. Simon Jr., Anne L. Plant, Sumona Sarkar, John T. Elliott, Sheng Lin-Gibson
Cell therapy products (CTPs) need quantitative, validated, and robust assays to support informed decision making during their development, manufacturing, and regulation. These products, the materials involved in their production and the methods for

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

May 22, 2016
Author(s)
Kiran Bhadriraju, Michael W. 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
