OBJECTIVE: Mesenchymal stem cells (MSCs) have been deeply investigated in regenerative medicine because of their crucial role in tissue healing, such as tissue regeneration. Dental-derived stem cells (d-DSCs) are easily available from dental tissues, which can be isolated from all age patients with minimal discomfort. PATIENTS AND METHODS: Normal unerupted third molars tooth buds were collected from adolescents' patients underwent to extractions for orthodontic reasons. The expression of the genes Kruppel-like factor 4 (Klf-4), octamer-binding transcription factor 4 (Oct-4), homeobox transcription factor Nanog (NANOG) was investigated in d-DSCs obtained from dental bud (DBSCs), differentiated toward osteoblastic phenotype and not. RESULTS: Our results showed that DBSCs expressed Oct-4, Nanog, and Klf-4 in undifferentiated conditions and interestingly the expression of such genes increased when the cells were kept in osteogenic medium. CONCLUSIONS: These attractive stemness properties, together with the effortlessly isolation, during common oral and maxillofacial surgical procedures, from undifferentiated tissues such as dental bud, make this kind of d-DSCs a promising tool in regenerative medicine, having the potential for clinical applications, and reinforcing the present challenge to develop new preventive and healing strategies in tissue regeneration.

Abstract

OBJECTIVE: Mesenchymal stem cells (MSCs) have been deeply investigated in regenerative medicine because of their crucial role in tissue healing, such as tissue regeneration. Dental-derived stem cells (d-DSCs) are easily available from dental tissues, which can be isolated from all age patients with minimal discomfort. PATIENTS AND METHODS: Normal unerupted third molars tooth buds were collected from adolescents' patients underwent to extractions for orthodontic reasons. The expression of the genes Kruppel-like factor 4 (Klf-4), octamer-binding transcription factor 4 (Oct-4), homeobox transcription factor Nanog (NANOG) was investigated in d-DSCs obtained from dental bud (DBSCs), differentiated toward osteoblastic phenotype and not. RESULTS: Our results showed that DBSCs expressed Oct-4, Nanog, and Klf-4 in undifferentiated conditions and interestingly the expression of such genes increased when the cells were kept in osteogenic medium. CONCLUSIONS: These attractive stemness properties, together with the effortlessly isolation, during common oral and maxillofacial surgical procedures, from undifferentiated tissues such as dental bud, make this kind of d-DSCs a promising tool in regenerative medicine, having the potential for clinical applications, and reinforcing the present challenge to develop new preventive and healing strategies in tissue regeneration.
