I ricercatori del King's College di Londra sono riusciti a creare denti nuovi a partire da cellule gengivali umane e da cellule di topi. I dentini ibridi sono poi cresciuti con successo nella bocca di topolini.
Si tratta di un importante passo avanti nello sviluppo di denti in provetta da usare in sostituzione di quelli malati in individui adulti e quindi di una nuova era per l'implantologia.
Finora i denti sono stati ricostruiti in laboratorio, ma sempre usando cellule staminali embrionali che però nella pratica sono difficilmente reperibili e quindi non utilizzabili.
