Mechanical Actuation of Organoids in Synthetic Microenvironments.

Organoids are a powerful model system to explore the role of mechanical forces in sculpting emergent tissue cytoarchitecture. The modulation of the mechanical microenvironment is most readily performed using synthetic extracellular matrices (ECM); however, such materials provide passive, rather than active force modulation. Actuation technologies enable the active tuning of mechanical forces in both time and magnitude.

Generation of human gastric assembloids from primary fetal organoids.

Purpose: Understanding human gastric epithelium homeostasis remains partial, motivating the exploration of innovative in vitro models. Recent literature showcases the potential of fetal stem cell-derived organoids in developmental and disease modelling and translational therapies. To scale the complexity of the model, we propose to generate assembloids, aiming to increase gastric maturation to provide new structural and functional insights.
