Author(s)
Eun Jin Lee, Peter Lialios, Micaila Curtis, James Williams IV, Yoontae Kim, Paul Salipante, Steven Hudson, Mandy Esch, moshe levi, Joanna Kitlinska, Stella Alimperti
Glucocorticoids (GCs) are standard-of-care treatments for inflammatory and immune disorders, and their long-term use increases the risk of osteoporosis. Although GCs decrease bone functionality, their role in bone microvasculature is incompletely

Enabling Global Image Data Sharing in the Life Sciences

December 23, 2024
Author(s)
Anne L. Plant, Peter Bajcsy
Public, reference data are one of the most important foundational resources in the modern life and biomedical sciences. Over the last 40 years, the public release and availability of genomic and macromolecule structural databases accelerated discovery

Tyler Nelson, Jose Tarazona, John Wambaugh, Jun-young Yang, Changwoo Yu, Suzanne Fitzpatrick
The webinar series and workshop titled Trust Your Gut: Establishing Confidence in Gastrointestinal Models–An Overview of the State of the Science and Contexts of Use was co-organized by NICEATM, NIEHS, FDA, EPA, CPSC, DoD, the Johns Hopkins Center for

Mechanism of Action, Potency and Efficacy: Considerations for Cell and Gene Therapies

April 1, 2024
Author(s)
Carl Simon Jr., Anne L. Plant, Catherine Zander, Erich Bozenhardt, Christina Celluzzi, David Dobnik, Melanie Grant, John Hughes, Uma Lakshmipathy, Kok-Seong Lim, Laura Montgomery, Hesham Nawar, Thiana Nebel, Linda Peltier, James Sherley, Rouzbeh Taghizadeh, Eddie Tan, Sandrine Vessillier
One of the most challenging aspects of cell and gene therapy products (CGTPs) is defining mechanism of action (MOA), potency and efficacy of the product. This perspective examines these concepts and presents helpful ways to think about them through the

Mechanical Regulation of Oral Epithelial Barrier Function

April 25, 2023
Author(s)
Eun Jin Lee, Paul Salipante, Anthony Kotula, Dana Graves, Stella Alimperti, Yoontae Kim
Epithelial cell function is modulated by mechanical forces imparted by the extracellular environment. The transmission of forces onto the cytoskeleton by modalities such as mechanical stress and matrix stiffness is necessary to address by the development

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

Variability in genome-engineering source materials: Consider your starting point

March 10, 2023
Author(s)
Simona Patange, Sierra Miller, Samantha Maragh
The presence and impact of variability in cells as the source material for genome engineering are important to consider for the design, execution and interpretation of outcomes of a genome-engineering process. Variability may be present at the genotype and

Biglycan regulates bone development and regeneration

February 16, 2023
Author(s)
Reut Shainer, Vardit Kram, Tina Kilts, Andrew Doyle, Inbal Shainer, Carl Simon Jr., Jinyang Zeng-Brouwers, Liliana Schaefer, Marian Young
Endochondral bone development and regeneration relies on activation and proliferation of periosteum derived cells (PDCs). Biglycan (Bgn), an extracellular matrix component, is known to be expressed in bone and cartilage, however little is known about its
