Dental tissues as adult stem cell source

The document discussed the potential of dental tissues as a source of adult stem cells, highlighting their multipotent nature and accessibility compared to traditional sources like bone marrow. Dental stem cells, first isolated from dental pulp, showed similar characteristics to mesenchymal stem cells (MSCs) from bone marrow, with the ability to differentiate into various cell types. Different dental tissues from the same donor exhibited varying stem cell characteristics, with root papilla cells showing high transcription factor expression and dental follicle cells enhancing bone formation. A significant advantage of dental tissues is their availability at a later age, around 20, compared to other sources. The document also mentioned advancements in cryopreservation methods for dental tissues, which could allow for their long-term storage and future use in regenerative medicine.
