Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms

January 20, 2025
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

From animal testing to in vitro systems: advancing standardization in microphysiological systems

February 15, 2024
Author(s)
Darwin Reyes-Hernandez, Mandy Esch, Lorna Ewart, Rohollah Nasiri, Anna Herland, Carolina Lucchesi, Kyung Sung, MONICA PIERGIOVANNI, Jelena Vukasinovic, James Shoemaker, Nureddin Ashammakhi
Limitations with cell cultures and experimental animal-based studies have had the scientific and industrial communities searching for new approaches that can provide reliable human models for applications such as drug development, toxicological assessment

Critical considerations for the design of multi-organ microphysiological systems (MPS)

September 9, 2021
Author(s)
Mridu Malik, Yang Yang, Parinaz Fathi, Gretchen Mahler, Mandy Esch
The process of identifying new drugs and getting them approved for use in patients requires extensive preclinical studies and clinical trials. Preclinical studies rely on in vitro experiments and animal models of human diseases. The reliability of data

Near-Infrared Emitting Dual-Stimuli-Responsive Carbon Dots from Endogenous Bile Pigments

August 12, 2021
Author(s)
Parinaz Fathi, Parikshit Moitra, Madeleine M. McDonald, Mandy Esch, Dipanjan Pan
Careful selection of carbon dot precursors and surface modification techniques has allowed for the development of carbon dots with strong near-infrared fluorescence emission. However, the rational selection of tetrapyrrolic carbon dot precursors to obtain

Electron and x-ray focused beam-induced cross-linking in liquids: Toward rapid continuous 3D nanoprinting and interfacing using soft materials

September 15, 2020
Author(s)
Tanya Gupta, Evgheni Strelcov, Glenn Holland, Joshua D. Schumacher, Yang Yang, Mandy Esch, Vladimir Aksyuk, Patrick Zeller, Matteo Amati, Luca Gregoratti, Andrei Kolmakov
Additive fabrication of biocompatible 3D structures out of liquid hydrogel solutions has become pivotal technology for tissue engineering, soft robotics, biosensing, drug delivery etc. Electron and X-ray lithography are well suited to pattern nanoscopic

Lymphatic Vessel on a Chip with Capability for Exposure to Cyclic Fluidic Flow

September 7, 2020
Author(s)
Parinaz Fathi, Glenn E. Holland, Dipanjan Pan, Mandy B. Esch
Lymph nodes comprise a complex organ system that is essential in regulating the development of host immune responses. Due to the complexity of lymph nodes and the lack of animal models that can accurately replicate the lymphatic functionality of humans

Pumpless Microfluidic Devices for Generating Healthy and Diseased Endothelia

September 27, 2019
Author(s)
Yang Yang, Parinaz Fathi, Glenn Holland, Dipanjan Pan, Nam Wang, Mandy Esch
We have developed a pumpless cell culture platform that can recirculate small amounts of cell culture medium (400 µL) in a unidirectional or bidirectional flow pattern. The device produces an average wall shear stress of up to 0.587 Pa ± 0.006 Pa without

Biodegradable biliverdin nanoparticles for efficient photoacoustic imaging

June 27, 2019
Author(s)
Parinaz Fathi, Knox J. Hailay, Dinabandhu Sar, Indu Tripathi, Ostadhossein Fatemeh, Misra K. Santosh, Mandy Esch, Jefferson Chan, Dipanjan Pan
Here we report the synthesis of nanoparticles composed of Biliverdin cross-linked with a bifunctional amine functionalized linker. The nanoparticles display high absorbance at 365 nm and 680 nm, fluorescence when excited at 365 nm, and photoacoustic

Self-contained, Low Cost Body-on-a-Chip Systems for Drug Development

February 17, 2017
Author(s)
Ying Wang, Oleaga Carlota, Long Christopher, McAleer Christopher, Paula Miller, James J. Hickman, Michael L. Shuler, Mandy B. Esch
Integrated multi-organ microphysiological systems are an evolving tool for preclinical evaluation of the potential toxicity and efficacy of drug candidates. Such systems, also known as “Body-on-a-Chip” devices, have a great potential to increase the
