Regenerative Medicine – Can We Regrow Our Organs and Limbs

Have you ever wondered how some animals, like newts and salamanders, can regrow their limbs after they become detached? Many scientists have been studying this phenomenon in the hopes of one day being able to apply it to humans. Is there anything they’ve discovered, though? Yes, it is correct. Is such regeneration, however, genuinely possible? Scientists have just learned why newts recover and are now looking to the future to see whether we may apply these new insights to regrow our own limbs.Learn more by visiting San Antonio Shoulder Pain Doctor

Scientists recently discovered a protein in newts that causes them to regrow their detached limb. Salamandridae newts are found in North America, Europe, and Asia and belong to the Salamandridae family. They can regenerate limbs, eyes, spinal cords, hearts, intestines, and upper and lower jaws, among other things. For a long time, the process of regeneration in these tiny critters has been a mystery. However, all of the current study has paid off, since the protein discovered, known as nAG, was discovered to originate in nerve and skin cells. This protein is responsible for the formation of blastema, a mass of undifferentiated cells capable of growth and regeneration. The blastema are the cells that allow these animals to rebuild their severed body parts. Blastemata is typically present in the early phases of an organism’s development, such as embryonic stages. As a result, it makes sense that creatures like salamanders, as opposed to humans or even frogs, would still contain these cells, as salamanders are still considered far more ‘basic’ organisms than more sophisticated species.

So, if these cells are only found in ‘primitive’ creatures, what does this suggest for us? This is a question that researchers are only now posing to one another. Is it possible that humans will be able to use these cells to rebuild a heart or a severed fingertip? All of this connects to the topic of regenerative medicine and stem cell research, where there have recently been many heated debates about such regeneration processes. Will the application of such results to humans impose a burden on many people’s morality and beliefs? Or will these new discoveries contribute to a more positive human existence? These questions will certainly arise as scientists labour around the clock to obtain a better knowledge of molecular communication pathways and more in order to figure out what exactly is driving the regeneration so that they might potentially replicate these systems.
