Humans Can Regenerate Their Teeth Just Like Sharks?

How would it be if humans were capable of regenerating teeth like sharks and prevent tooth decay and other dental procedures? Share your thoughts in the comment section below. And now, we’re going to answer the million-dollar question – can humans regenerate their teeth just like sharks?

Here’s what you need to know – the experts say that although humans have same cells, their ability to regenerate teeth is limited. However, a study has identified a network of genes that allows sharks to develop and regenerate their teeth throughout their lives.

The lead researcher and the author of this study, Gareth Fraser of the University of Sheffield in Britain said:

“We know that sharks are fearsome predators and one of the main reasons why they are so successful in hunting prey is due to their ranks pointing backwards, sharp teeth that regenerate quickly throughout his life, and therefore they are replaced before the decline.”

You should also know that the researchers in this study have identified how to form a special set of epithelial cells called the dental lamina, which are responsible for the continuation of a lifetime of tooth development and regeneration in sharks. The genes also allow sharks to replace the rows of teeth using a system of belt-like conveyor Humans also have this set of cells, which facilitate the production of replacement teeth, but are formed only two sets -. Baby and adult teeth -. before losing this set of specialized cells

And these genes “tooth”, therefore, make all the teeth in vertebrates’ sharks mammals, however, in mammals like humans, the ability to regeneration of teeth, using these genes, has been greatly reduced over time. Gareth Fraser also mentioned that the Jaws movies taught us that it is not always safe to enter the water, but this study shows that perhaps we need in order to develop therapies that can help humans with tooth loss.

Through analyzing the teeth of catshark embryos, the researchers characterized the expression of genes during stages of early shark tooth formation.They found that these genes participate in the initial emergence of shark’s teeth and are re-deployed for further tooth regeneration.

The study suggests that at the beginning of the sharks’ evolutionary history, their teeth were most likely continuously regenerated and used a core set of genes from members of key developmental signaling pathways, which were instrumental in sharks evolving to maintain the ability to re-deploy the genes to replace teeth when needed.
