Low‐Field MRI as a Multiparametric Tool for Large Engineered Tissue Characterization

Yilbert Gimenez, Valernst Martial Gilmus, Elliott Cowles, Lucie Essayan et autres

Advances in 3D bioprinting have enabled the fabrication of large and complex engineered tissues, but their increasing size demands non-invasive tools for monitoring structure, maturation, and perfusion. Magnetic Resonance Imaging (MRI) offers unique multiparametric capabilities, yet high-field systems remain costly and inaccessible …

Photoprotection of a novel resveratrol analogue: insights from 2D, 3D, and endothelialized bioprinted human skin models

Ana Júlia Pasuch Gluzezak, Lucie Essayan, Céline Thomann, Jean Leandro dos Santos et autres

Excessive exposure to ultraviolet (UV) radiation induces oxidative stress, DNA damage, and extracellular matrix (ECM) disorganization, contributing to skin aging and disease. To enhance photoprotection strategies, antioxidant molecules have been explored as complementary agents to conventional UV filters. Here, we investigated the …

3D Plastronics Culture Chambers and Benchtop MRI Setup Toward Tissue Engineering Applications

Valernst Martial Gilmus, Yilbert Gimènez, Tony Gerges, Philippe Lombard et autres

ABSTRACT The rise of low‐field benchtop MRI offers exciting opportunities for non‐invasive, volumetric imaging of large biofabricated tissues in standard tissue engineering labs. Although low‐field benchtop MRI scanners provide a cost‐effective and accessible option, their performance is often restricted by low signal‐to‐noise …

Integration of multi-modal monitoring for dynamic control of large-scale 3D tissue bioreactors

Laura Chastagnier, Sarah Pragnère, Yilbert Gimènez, Céline Loubière et autres

The translation of tissue engineering toward clinically relevant large-scale biofabrication requires continuous and non-invasive monitoring of tissue maturation. However, few studies provide an integrated and operational demonstration of how such tracking can be effectively achieved in real bioreactor environments. Here, we propose …

Morphometric study of bioprinted hydrogel deformation during histological preparation

Lucie Essayan, Alexandre Dufour, Emma Petiot, Christophe André Marquette

. Quite often, deformation and shrinkage occur during the histological preparation, which are difficult to predict and qualify. The present study investigates the morphometric changes in bioprinted hydrogels composed of alginate and gelatine, common tissue engineering materials, focusing on three morphologies: full …

Biofabrication of Spatially Organized Temporo‐mandibular Fibrocartilage Assembloids

Alexandre Dufour, Lucie Essayan, Beomjoon Kim, Vincent Salles et autres

The combination of mesenchymal stem cell (MSC) spheroids and polymeric scaffolds has been actively explored for engineering organized hyaline cartilage; however, its application to other types of cartilage remains under-explored. The temporo-mandibular joint (TMJ) fibrocartilage is a stratified tissue whose recapitulation remains …
