The cell re-association-based whole-tooth regeneration strategies in large animal, Sus scrofa.

We characterized the morphogenesis and interaction of single-tooth germ cells in vitro, and first addressed efficient long-term survival and growth through transplantation of pig bioengineered tooth bud under mouse subrenal capsules or in mouse jawbones, where it can develop into large size tooth. Our study extends the feasibility of whole-tooth regeneration in large animal.
