Enamel Regeneration


Scientists have developed organoids from stem cells capable of producing dental enamel proteins. The research aims to use these advancements for dental treatments, including repairing damaged teeth or entirely regenerating lost ones.

This advance is viewed as a pivotal initial step toward innovative therapies for the repair and regeneration of teeth.

Stem cells have been used to produce organoids that release the proteins responsible for forming dental enamel, a substance that shields teeth from harm and decay. This initiative was led by a multi-disciplinary team of researchers from the University of Washington in Seattle.

“This is a critical first step to our long-term goal to develop stem cell-based treatments to repair damaged teeth and regenerate those that are lost,” said Hai Zhang, professor of restorative dentistry at the UW School of Dentistry and one of the co–authors of the paper describing the research.

The findings are published today in the journal Developmental Cell. Ammar Alghadeer, a graduate student in Hannele Ruohola-Baker’s laboratory in the Department of Biochemistry at the UW School of Medicine was the lead author on the paper. The lab is affiliated with the UW Medicine Institute for Stem Cell and Regenerative Medicine.

The researchers explained that tooth enamel protects teeth from the mechanical stresses incurred by chewing and helps them resist decay. It is the hardest tissue in the human body.

Enamel is made during tooth formation by specialized cells called ameloblasts. When tooth formation is complete, these cells die off. Consequently, the body has no way to repair or regenerate damaged enamel, and teeth can become prone to fractures or be subject to loss.     READ MORE...
