Culture of Human Dental Pulp Cells at Variable Times Post-Tooth Extraction

This study found that stem cells derived from root apical papilla in extracted wisdom teeth demonstrated the strongest potential for osteogenic differentiation compared to those from dental pulp and dental follicle.

This study observed that human dental pulp stem cells can differentiate into adipocytes and osteocytes, but their potential for neural differentiation remains uncertain due to similar responses seen in undifferentiated cells.

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.

This review discusses the potential of dental tissues as an alternative source of adult stem cells for regenerative medicine but reports no new experimental results, emphasizing the need for effective preservation methods.

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.
