New Stem Cell Research Reveals Tooth Regeneration Mechanism
Scientists have discovered how teeth might be regrown using stem cells.
They studied mice to watch how teeth grow.
Researchers found two groups of stem cells that help build teeth and the bone around them.
One group is found at the bottom of the tooth and helps make the root.
The other group is around the tooth and forms the bone that holds the tooth in place.
By understanding how these cells work, scientists hope to develop new treatments to regrow lost teeth instead of using implants.
Researchers identified two stem cell lineages involved in tooth development.
The research focused on tooth root and alveolar bone formation.
Studies used genetically modified mice to track tooth development.
One lineage originates from apical papilla cells.
The other lineage originates from cells in the dental follicle.
