An Inductive Signaling Network Regulates Mammalian Tooth Morphogenesis With Implications for Tooth Regeneration

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This study reported the establishment of a chemically defined culture system that supports tooth reconstitution and detailed how co-stimulation of specific signaling pathways can sustain tooth development stages and initiate enamel formation, providing insights into tooth regeneration mechanisms.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

In this study, fingertip regeneration in mice was associated with specific signaling pathways involving hair follicles and hedgehog signaling, with potential implications for improving human hand injury treatments.
