[Dental stem cells: myth or hope in neuroregenerative medicine?].

The use of dental stem cells has raised many hopes in the development of new treatments for neurodegenerative diseases. According to current statistics, about 1 in 6 people in the world would be affected by a neurological disease. This number continues to increase as the world's population ages, making neurodegenerative diseases probably the one of the major challenges of public health in the 21st century. Neurodegenerative diseases are characterized mainly by a progressive loss of cognitive abilities and patient autonomy related to loss and degeneration of neurons in brain structures. Unfortunately, today, the only treatments available for this type of disease do only relieve the symptoms, they do not treat them, and few clinical trials have been truly convincing to date. Hence, hope lies for these diseases in the development of other therapeutic approaches. As such, dental stem cells could be a promising area of research because of their rapid growth, their great capacity for differentiation into different types of cells (among neuronal ones for some of them) and how easy they can be obtained, without raising ethical issues as for example for embryonic stem cells.
