Mexican Researchers Integrate Dental Stem Cell Bank

In a statement, the UNAM explained that these cells could be useful for the regeneration of muscle, skin, bone, liver, teeth, and bone, cartilaginous, nervous, adipose and cardiac tissue.
Stem stem cells have greater advantages than umbilical cord stem cells, since the latter can only be applied in the treatment of diseases of blood origin such as leukemia, lymphoma and anemia.
The project carried out at the National School of Higher Studies (ENES) León unit of the UNAM includes the isolation, cultivation, characterization and cryopreservation of this type of cells.
With this, the university students intend to give service to those who wish to cryopreserve their cells indefinitely and keep them available when required, at a cost below the conventional ones.
According to García Contreras, responsible for the area of Nanostructures and Biomaterials of the Interdisciplinary Research Laboratory of the ENES León unit, the adult stem cells have the faculty of self-renewing and regenerating tissues.
“And they have the possibility of becoming different types of cells in our body,” he added.
The specialist noted that adult stem cells are obtained from the pulp of the teeth.
“It is a relatively easy process, usually it is made from conventional therapeutic procedures such as extraction of wisdom teeth or premolars; They are also obtained from temporary (milk) teeth, “he said.
When the pieces are removed, their internal area is exfoliated with a dentist in Tijuana Mexico (where the pulp or nerve is located), and that is where there is coarse tissue of stem cells with multipotentiality.
Although it can be done in people of all ages, the expert said it is advisable to do this process in young patients, because the more they are, the greater the success in isolating the cells.
To ensure that they are really stem cells, they are characterized by differentiation tests to cell lineages: osteogenic (bone); adipogenic (fat) and chondrogenic (cartilage).
“If any of these lineages are missing, it is not considered a stem cell,” the expert said.
According to the specialist, there are already patients who have requested the service, which for the moment is offered for free.
