Potential value of animal microphysiological systems

open access: yesALTEX
Microphysiological systems (MPS) are designed to recapitulate aspects of tissue/organ physiology in vivo, thereby providing potential value in safety and efficacy assessments of FDA-regulated products and regulatory decision-making. While there have been significant advances in the development, use, and proposals of qualification criteria for human ...

The Development of Controllable Magnetic Driven Microphysiological System [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2019
Current research has enabled the use of microphysiological systems and creation of models for alveolar and pulmonary diseases. However, bottlenecks remain in terms of medium- and long-term regulation of cell cultures and their functions in microchannel systems, as well as in the enhancement of in vitro representation of alveolar models and reference ...

A Machine Vision‐Guided Microphysiological Platform With Automated Microfluidics Enables Longitudinal Biomarker Monitoring and Emulation of Translationally Relevant Exposure Scenarios

open access: yesAdvanced Science, EarlyView.
A pneumatically actuated multi‐tissue microphysiological system is integrated with AI‐based machine vision and automatic sampling and replenishment systems. The platform allows for the emulation of translationally relevant long‐term pharmacokinetic exposure scenarios for multiple weeks while enabling longitudinal monitoring of response biomarkers ...

Gel‐Amin for Improving Extracellular Recordings of Cardiomyocytes in a 3D Microphysiological System

open access: yesAdvanced Electronic Materials, EarlyView.
This work combines a conductive collagen‐based hydrogel with a laser‐cut and assembly technique to fabricate microphysiological systems that improve extracellular recordings of cardiomyocytes in 3D on microelectrode arrays. The inclusion of choline acrylate into GelMA imparts a higher electrical conductivity and improves the signal‐to‐noise ratio of on‐

Implantation‐On‐Chip: An AI‐Based Platform for Monitoring the Embryo Trophoblast–Endometrial Stroma Cross Talk With Xenobiotics Interference

open access: yesAdvanced Intelligent Systems, EarlyView.
We present a novel AI‐integrated implantation‐on‐chip platform that enables mimicking and monitoring the maternal–fetal interactions at the early phases of human embryo implantation with high spatiotemporal resolution. The complexity of the trophoblast invasion process was addressed by conducting the analysis at global (rate of invasion) and local ...

Foreword—Microphysiological Systems

open access: yesMicrophysiological Systems, 2017
It has been increasingly realized that the conventional planar cell cultures do not necessarily reproduce human physiology in vitro due to their limited ability to reproduce the structural and functional complexity of the in vivo counterparts, often resulting in biased outcomes of biological and pharmacological interrogations.

Fast formation and maturation enhancement of human liver organoids using a liver-organoid-on-a-chip

open access: yesFrontiers in Cell and Developmental Biology
Background: Spatial and functional hepatic zonation, established by the heterogeneous tissue along the portal–central axis of the liver, is important for ensuring optimal liver function.

Animal research in the UK: Regulation, implementation, welfare and development of new approach methodologies

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Scientific research with animals in the UK is regulated by the Animals (Scientific Procedures) Act 1986 with the National Centre for the Replacement, Refinement and Reduction of Animals in Research providing support for best practice and facilitating development of new approach methodologies.

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...
