Humans unfortunately don’t have the ability to regrow naturally or artificially one of our body parts. Instead, we use prosthetic legs or arms to fill the missing body part. This isn’t ideal but it’s the best way to restore our abilities. Most animals are similar to us with the exception of salamanders, starfish, crabs, and lizards which have the capability of filling the regeneration of at least some limbs.
Lately, scientists at Tufts University and Harvard’s Wyss Institute published a study that showed a frog with a missing limb being treated with a five-drug cocktail using a wearable bioreactor in the stump. After the 24-hour exposure to the drug, it took 18 months for the frog to restore its limb nearly fully. This was the first of its kind successful procedure which led to a significant milestone in medicine and surgery. The next big step is to test the drug on mammals and with a little hope of success, one day a similar drug can be implemented on humans.
In my opinion, the journey to imposing this drug on humans is still very long. By the time more experiments are done and tests on a larger variety of animals will be conducted, a new technology might be introduced. The early stage of the five-drug cocktail might be a false hope for currently disabled humans that had a body part amputated.

Medical technology is expanding exponentially. I was a bit surprised because I was not expecting an experiment on a frog. However, this does give some sort of hope for a few disabled people.
It’s a very big step for a medicine. Just imagining that one day we could be capable of restoring our limbs is something I would never think of.
