Whole-Tooth Regeneration by Allogeneic Cell Reassociation in Pig Jawbone.

Abstract

The methods developed in this study to manipulate pig tooth germ cells <i>in vitro</i> and <i>in vivo</i> provide a reference for studying whole-tooth regeneration and tooth development in large animals. Of importance, compared with conventional ectopic tooth regeneration, conducted in the omentum, subcutaneous tissues, or kidney capsule (among other locations) with low with immune reactivity in rodent models, this study achieved orthotopic regeneration and development of whole teeth in a large mammal, representing a large stride toward the realization of tooth regenerative therapy for humans with missing teeth.
