Paleobiology: A Tooth for a Tooth [PDF]
Many vertebrates replace teeth through shedding of the functional tooth. New analyses of a fossil fish demonstrate that shedding involved tooth resorption, a primitive feature in bony fishes, but absent in sharks and their relatives.

Deciduous autologous tooth stem cells regenerate dental pulp after implantation into injured teeth
Dental pulp regeneration by tooth stem cells promotes recovery of damaged teeth in animal models and human patients. Tooth stem cells regenerate smiles Dental pulp necrosis is one of the most common pathological conditions that results in tooth loss ...

IFT140+/K14+ cells function as stem/progenitor cells in salivary glands
Stem/progenitor cells are important for salivary gland development, homeostasis maintenance, and regeneration following injury. Keratin-14+ (K14+) cells have been recognized as bona fide salivary gland stem/progenitor cells.

DPP promotes odontogenic differentiation of DPSCs through NF-κB signaling
Dentin phosphophoryn synthesized and processed predominantly by the odontoblasts, functions as both structural and signaling protein. Mechanistic studies revealed that DPP stimulation of DPSCs positively impacted the differentiation of DPSCs into ...
