[Single-cell spatiotemporal atlas of tooth development: progress and prospects].

Single-cell and spatial multi-omics technologies enable the simultaneous analysis of thousands of cells in various states, revealing their transcriptional profiles, chromatin accessibility, and spatial positioning. Recent advances in single-cell multi-omics have led to significant discoveries regarding the definition, function, evolution, and interaction of various cell subtypes during tooth development. We summarize key findings from recent single-cell multi-omics studies on tooth development, highlighting their contributions to the field and discussing future perspectives in dental developmental genomics research.
