Frog was able to regrow a lost leg after being treated with a cocktail of drugs, now scientists are hoping to apply the same technology to humans
Frog grows functional leg
The medicine was administered to the frog during the day, regeneration took 18 months, which was a significant step forward for regenerative medicine.

In the future, medicines can be used to turn on regeneration abilities. in human patients for tissue or organ repair, writes The Guardian.
Who can regenerate
As the scientists explained, the experiment showed that frogs, other animals and people can have dormant regenerative abilities, which can be activated.
Many creatures are able to fully regenerate at least some of their limbs – for example, salamanders, starfish, crabs and lizards.
And flatworms can even be cut into pieces, each of which reconstructs the whole organism.
Why do people not grow legs
Humans also have some ability to regenerate: the liver can grow to its full size after being split in half, and children may even grow fingertips.
However, in humans, it is impossible to restore the loss of a large complex limb by any natural process.
Rapid formation of scar tissue which protects a person from blood loss, infection and death, also prevents re-growth.
How to regenerate a person
However, the frog experiment was able to halt the formation of scar tissue and regenerate a limb that it can use to swim.
Covering an open wound with a liquid medium with the right cocktail of drugs could provide the necessary signals to kick-start the regenerative process in humans as well, the researchers think.
