0This research article from Nature Genetics presents a multiscale analysis of the cellular and genetic factors that govern skeletal disease. By developing a single-cell RNA sequencing map of the endosteal compartment in mice, researchers identified 34 distinct cell types and their unique gene programs. These findings were integrated with human genomic data from the UK Biobank to pinpoint specific effector genes linked to bone mineral density and rare skeletal disorders. The study highlights the critical roles of endothelial and vascular smooth muscle cells alongside traditional bone cells in maintaining skeletal integrity. To ensure accuracy, the team conducted functional validation using over 1,000 genetically modified mouse models. Ultimately, this comprehensive framework provides a web-based platform to help scientists prioritize new therapeutic targets for treating musculoskeletal diseases.
