Mouse tooth stem cells used to create breast cells that produce milk

Recent research has shown that dental epithelial stem cells, in addition to the ability to generate all types of epithelial cells of the teeth, can also be used to create tooth cells. This is confirmed by a study published in Cells and conducted by a team of researchers under the direction of Professor Timios Mitsiadis of the Institute of Oral Biology at the University of Zurich (UZH).

The researcher has shown that stem cells from mice’ incisors, especially young ones with growing incisors, can be used to create mammary glands in female mice. “The results show that dental stem cells contribute to breast regeneration and are able to generate all populations of breast cells and, even more surprisingly, produce milk,” says Miciadis, who also adds that these studies show that this discovery “opens up new possibilities for the development of stem cell therapy that can be used for breast regeneration in the future.”

The study once again shows how useful epithelial stem cells can be taken from a particular area of the body, in this case from the teeth, which can then be used to create tissues or other cells from other areas of the body, for a very high clinical potential, which is probably not yet fully understood in terms of full exploitation.
