Stem cells hide the universal key to the regeneration of any tissues, because they are able to transform any body cells, including teeth. According to Medical Express, the Dlk1 gene enhances the process of stem cell activation and tooth tissue regeneration.
Plymouth University researchers have discovered a new population of mesenchymal stem cells (the stem cells that make up the muscles and bones) in ever-growing mouse incisors. These cells, it turned out, contribute to the formation of dentin (the hard tissue of the tooth that makes up its main part).
When activated, they send a signal to the original tissue cells in order to effectively control the number of cells produced. And this happens through the Dlk1 gene. It has also been proven that this gene enhances the process of tissue regeneration. That is, acting only on it, it is possible to solve the problem of caries, injuries and other tooth injuries.
