简介：

Overview

This study establishes a standardized suture expansion mouse model to investigate craniofacial sutures' mechanobiological changes and bone remodeling under tensile stress. Using the PEGASOS tissue clearing technique combined with viral labeling, the research enables detailed three-dimensional visualization of these dynamic biological processes.
