A High-Throughput Workflow to Study Remodeling of Extracellular Matrix-Based Microtissues.

Area of Science:

• Biotechnology and Biomedical Engineering
• Cell Biology
• Extracellular Matrix Research

Background:

• Extracellular matrix (ECM) remodeling is crucial in various physiological and pathological processes, including cancer, fibrosis, and wound healing.
• Current 3D cell culturing systems often lack the throughput and physiological relevance needed for studying complex diseases and drug discovery.
• Understanding cell-ECM interactions and ECM remodeling at multiple levels is essential for developing effective therapies.

Purpose of the Study:

• To develop and validate a high-throughput microtissue-microwell workflow for studying ECM remodeling.
• To demonstrate the utility of this system for investigating progressive, heterogeneous diseases.
• To assess the feasibility of cryopreserving microtissue constructs for future research and drug development.

Main Methods:

• Development of a microtissue-microwell platform for controlled 3D cell culture.
• Implementation of various assays to analyze ECM remodeling at molecular, cellular, and tissue levels.
• Evaluation of microtissue construct viability, proliferation, and function after cryopreservation.

Main Results:

• The microtissue-microwell workflow enables high-throughput analysis of ECM remodeling.
• The system effectively models progressive and heterogeneous diseases, offering insights for drug discovery.
• Cryopreserved microtissues maintained high viability, proliferation, and ECM remodeling functions.

Conclusions:
