Imagine Regrowing Lost Limbs - It's a Step Closer With New Treatment That Helped Frogs Regenerate Amputated Legs:

A new treatment helped frogs regenerate their amputated legs - taking science one step closer to helping people regrow their body parts, too.

Our bodies connect us to the world. When people lose parts of their bodies to disease or traumatic injury, they often feel that they've lost a part of who they are, even experiencing a grief akin to losing a loved one. Their sense of personal loss is justified because unlike salamanders or snarky comic book characters like Deadpool, adult human tissues generally do not regenerate - limb loss is permanent and irreversible.

While there have been significant advances in prosthetic and bionic technologies to replace lost limbs, they cannot yet restore a sense of touch, minimize the sensation of phantom pains or match the capabilities of natural limbs. Without reconstructing the limb itself, a person won't be able to feel the touch of a loved one or the warmth of the sun.

[...] Our recent study in the journal Science Advances showed that just 24 hours of a treatment we designed is enough to regenerate fully functional and touch-sensitive limbs in frogs.
