Todd Streelman with cichlidsResearchers from the United Kingdom and United States have identified a common origin shared by teeth and taste buds in a fish with regenerative abilities. Regulated by the BMP signaling pathway, the results suggest that the oral organs have surprising regenerative capabilities and can be manipulated to express characteristics of different tissue types. As nearly a third of all adults over the age of 65 have lost all of their teeth, the collaboration between King’s College London and the Georgia Institute of Technology set out to understand tooth renewal in animals that have replacement and regeneration capabilities. The Georgia Tech team was led by J. Todd Streelman. Here is the original paper.
