3D-printed barriers with machine learning powered image analysis for enhanced wound healing assays
Wound healing assay is a standard method enabling investigation of cell proliferation and migration through a cell-free gap in a cell monolayer. Despite very common, it shows several weaknesses: lack of reproducibility and manual and time-based image analysis. Based on novel approach founded on innovative materials and AI-assisted processing of biological images, a promising automated barrier-wound healing assay is realized, achieving consistent results while retaining cells integrity. To increase assay accuracy, biocompatible 3D-printed resin inserts have been developed, facilitating precise control over shape and size of the wound. In parallel, a new image-detection algorithm powered by Deep Learning models was developed to identify cell-free area during the healing process, exceeding limitations of manual analysis. 3D-resin inserts combined with automated image analysis allowed the elimination of subjective errors and provided reproducible quantification of cell-free areas across multiple experiments.
Moreover, a dataset to train a Convolutional Neural Network for monitor healing over time was developed.
As proof of concept, this algorithm was tested on a cancer cell line stimulated by TGF-β, a drug stimulating cell migration.
Innovative design of biocompatible materials combined with Deep Learning for automatically processing high-throughput data enables standardized wound healing assay, increasing efficiency, reliability, and accuracy of results.
期刊介绍:
Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry.
The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
