Oral stem cells behave like foetal cells

Scientists have discovered a certain type of stem cell in adults that does not seem to age in the way other stem cells in the body do.

In a study by the American Friends of Tel Aviv University, published in the journal Stem Cells, scientists explained that stem cells of oral mucosa, the membrane that lines the inside of the mouth, do not suffer the same problems as other adult stem cells.

Embryonic stem cells are the subject of much ethical and moral debate, however, they are highly potent and pliant, especially compared to adult-derived cells which become less able to transform into the stem cells needed in scientific studies as the body ages.

Oral stem cells however have been found to be as yielding as embryonic stem cells which could open the door for further research into potential therapies for neurodegenerative, heart, autoimmune diseases and diabetes.

"Wounds in the oral mucosa heal by regeneration, which means that the tissue reverts completely back to its original state," explained author Professor Sandu Pitaru, adding that this type of healing is normally only seen in very young organisms and lower amphibians.
