Dental pulp has intrinsic capacity for self-repair. However, it is not clear whether dental pulp cells can be recruited endogenously for regenerating pulp tissues, including mineralizing into dentin. This work is based on a hypothesis that dental pulp stem/progenitor cells can be induced to migrate by chemotactic cytokines and act as endogenous cell sources(More)
Odontogenic keratocyst displaying foci of cartilaginous metaplasia in the connective tissue wall has been previously reported but is considered rare. We report a case of a 66-year-old man with an odontogenic keratocyst of the mandible. Benign-appearing metaplastic cartilage was observed in the wall of this cyst, as well as in the recurrence. A benign(More)
Fractures of the zygomatic complex and their treatment have been the focus of much attention in the last 30 years. Treatment frequently depends on the surgical findings, experience, and discretion of the surgeon. Treatment of zygomatic complex (ZMC) fractures often requires stabilization at the frontozygomatic (FZ) suture. Frodel' and Marentette' have(More)
Hematopoietic stem cells (HSCs) in the endosteum of mesoderm-derived appendicular bones have been extensively studied. Neural crest-derived bones differ from appendicular bones in developmental origin, mode of bone formation and pathological bone resorption. Whether neural crest-derived bones harbor HSCs is elusive. Here, we discovered HSC-like cells in(More)
