Recommendations on fit-for-purpose criteria to establish a quality management for microphysiological systems (MPS) and for monitoring of their reproducibility

May 14, 2024
Author(s)
David Pamies, Jason Ekert, Marie-Gabrielle Zurich, Olivier Frey, Sophie Werner, MONICA PIERGIOVANNI, Benjamin Freedman, Adrian Keong, Darwin Reyes-Hernandez, Hendrik Erfurth, Peter Loskill, Pelin Candarlioglu, Shan Wang, Thomas Hartung, Sandra Coecke, Glyn Stacey, Marcel Leist
Cell culture technology has seen great innovations and progress in the 21st centuryClassical single-cell and monolayer models have been replaced by more complex 3D models (e.g., reaggregates, spheroids, organoids) to improve the predictivity of in vitro

Nondestructive, Longitudinal, 3D Cell Viability Assessment in a Multi-well Plate System Using Electron Paramagnetic Resonance Oxygen Imaging

May 1, 2024
Author(s)
Safa Hameed, Navin Viswakarma, Eliyas Siddiqui, Greta Babakhanova, Carl Simon Jr., Boris Epel, Mrignayani Kotecha
Cell viability is an essential measurement for cell therapy, tissue engineered medical products (TEMPs), drug development, and many other biological processes and products. These systems rely on viable, healthy, and functional cells to work as intended

Heart-on-a-Chip Systems: Disease Modeling and Drug Screening Applications

February 14, 2024
Author(s)
Derrick Butler, Darwin Reyes-Hernandez
Cardiovascular disease (CVD) is the leading cause of death worldwide, casting a substantial economic footprint and burdening the global healthcare system. Historically, pre-clinical CVD modeling and therapeutic screening has been performed using animal

Report from the 2022 NIST Rapid Microbial Testing Methods (RMTM) Workshop

August 15, 2023
Author(s)
Stephanie Servetas, Nancy Lin, Nadratun Chowdhury, Scott Jackson, Jason Kralj, Sheng Lin-Gibson, Melody Sanders, Tara Eskandari
Safety and quality of advanced therapies, including cellular, gene, and tissue-engineered medical products, is paramount for success of these products. Sterility assurance testing confirming the absence of microbial contamination in advanced therapy

Three-dimensional, label-free cell viability measurements in tissue engineering scaffolds using optical coherence tomography

March 14, 2023
Author(s)
Greta Babakhanova, Anant Agrawal, Deepika Arora, Allison Horenberg, Jagat Budhathoki, Joy Dunkers, Joe Chalfoun, Peter Bajcsy, Carl Simon Jr.
In the field of tissue engineering, 3D scaffolds and cells are often combined to yield constructs that are used as therapeutics to repair or restore tissue function in patients. Viable cells are required to achieve the intended mechanism of action for the

Measuring Dimensionality of Cell-Scaffold Contacts of Primary Human Bone Marrow Stromal Cells Cultured on Electrospun Fiber Scaffolds

January 1, 2023
Author(s)
Carl Simon Jr., Peter Bajcsy, Joe Chalfoun, Michael Paul Majurski, Mary C. Brady, Mylene Simon, Nathan Hotaling, Nick Schaub, Allison Horenberg, Piotr Szczypinski, Dongbo Wang, Veronica DeFelice, Soweon Yoon, Stephanie Florczyk
The properties and structure of the cellular microenvironment can influence cell behavior. Sites of cell adhesion to the extracellular matrix (ECM) initiate intracellular signaling that direct cell functions such as proliferation, differentiation and

Fire Burn and Cauldron Bubble: What is in your Genome Editing Brew?

October 28, 2022
Author(s)
Simona Patange, Samantha Maragh
Genome editing is a rapidly evolving biotechnology with the potential to transform many sectors of industry such as agriculture, biomanufacturing, and medicine. This technology is enabled by an ever-growing portfolio of biomolecular reagents that span the

Sensor Technologies for Quality Control in Engineered Tissue Manufacturing

October 27, 2022
Author(s)
Mary Clare McCorry, Marcie Black, Chrysanthi Williams, Greta Babakhanova, Sumona Sarkar, Nathan Swami, Katherine A. Mirica, Sarah Boermeester, Abbie Underhill
The use of engineered cells, tissues, and organs has the opportunity to change the way injuries and diseases are treated. Commercialization of these groundbreaking technologies has been limited in part by the complex and costly nature of their manufacture

The NIH Somatic Cell Genome Editing program

April 7, 2021
Author(s)
Samantha Maragh
The move from reading to writing the human genome offers new opportunities to improve human health. The United States National Institutes of Health (NIH) Somatic Cell Genome Editing (SCGE) Consortium aims to accelerate the development of safer and more

Web Microanalysis of Big Image Data

February 1, 2018
Author(s)
Peter Bajcsy, Joe Chalfoun, Mylene H. Simon
This book looks at the increasing interest in running microscopy processing algorithms on big image data by presenting the theoretical and architectural underpinnings of a web image processing pipeline (WIPP). Software-based methods and infrastructure

High Resolution Surface Plasmon Resonance Imaging for Single Cells

November 30, 2014
Author(s)
Alexander Peterson, Michael Halter, Alessandro Tona, Anne 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
