The dental pulp is known to be highly heterogenous, comprising distinct cell types including mesenchymal stromal cells (MSCs), which represent neural-crest-derived cells with the ability to differentiate into multiple cell lineages. However, the cellular heterogeneity and the transcriptome signature of different cell clusters within the dental pulp remain to be established. To better understand discrete cell types, we applied a single-cell RNA sequencing strategy to establish the RNA expression profiles of individual dental pulp cells from 5- to 6-day-old mouse incisors. Our study revealed distinct subclasses of cells representing osteoblast, odontoblast, endothelial, pancreatic, neuronal, immune, pericyte and ameloblast lineages. Collectively, our research demonstrates the complexity and diversity of cell subclasses within the incisor dental pulp, thus providing a foundation for uncovering the molecular processes that govern cell fate decisions and lineage commitment in dental pulp-derived MSCs.
