Summary

Story summary

Researchers at Science Tokyo identified two stem cell lineages governing tooth root and alveolar bone development.
Using genetically modified mice, the team showed CXCL12-expressing cells in the apical papilla differentiate into odontoblasts and osteoblasts via Wnt signaling pathway.
A second dental follicle lineage involves PTHrP-expressing cells that form cementoblasts and osteoblasts under certain conditions.
The studies were published in Nature Communications in July 2025, advancing tooth biology and regenerative therapies.
