[Advances in tooth development studies based on single-cell RNA sequencing].

Abstract

Tooth development is a complex process of the orderly interaction between epithelium originating from the ectoderm and mesenchyme derived from cranial neural crest cells, which not only depends on cell genes regulatory network but also involves crosstalk between cells and their surrounding environment. Even within the same type of cellular populations, obvious heterogeneity may be observed. Single-cell RNA sequencing is a novel technology aimed at sequencing the transcriptome of individual cell. As a critical bridge linking genetic information from the genome to the functional proteome, transcriptome analysis at the single-cell level enables a deeper understanding of cellular heterogeneity and organ developmental trajectories. This approach provides a powerful tool for elucidating complex biological processes and identifying potential therapeutic targets. Here, we summarize the latest advances in employing single-cell RNA sequencing analysis to the process of tooth development, which will help provide insights into a better understanding of prosthodontics and regeneration.
