Stem Cell Research Discovers Two Cells That Could Lead To Regenerating Teeth And Bone

Researchers discovered two stem cell types that could regenerate teeth and bone by studying signaling pathways that control bone formation in the jaw. Using genetically engineered mice, scientists found that turning off Hedgehog signaling allows stem cells to develop into bone-forming cells, while the gene Foxf1 acts as a key controller. Testing with an FDA-approved drug successfully restored normal bone development, suggesting new therapies for severe gum disease and bone loss.
