Over the past few decades, scientific research into neural crest-derived stem cells has progressed rapidly. The migration and differentiation of neural crest-derived stem cells has been an interesting area of research. Stem cells within teeth originating from the embryonic neural crest have attracted increasing attention in clinical and scientific research because they are easy to obtain and have superb stemness. The stem cells within the teeth include dental pulp stem cells (DPSCs), dental follicle stem cells (DFSCs), stem cells from apical papilla (SCAPs), stem cells from human exfoliated deciduous teeth (SHEDs), and periodontal ligament stem cells (PDLSCs). To date, there have been several interesting studies focusing on dental pulp regeneration, neural regeneration and the revascularization for therapeutic applications.
