Humans may be able to regrow limbs like salamanders.

Scientist identifies signaling underlying regeneration

The mystery of why salamanders can regenerate a lost limb, but adult mammals cannot has fascinated observers for thousands of years. Now, a team of scientists has come a step closer to unraveling that mystery with the discovery of differences in molecular signaling that promote regeneration in...

"The axolotl can rebuild nearly any body part, including its heart, lungs, jaws, limbs, spinal cord, ovaries, tail, skin, and much more. It can even regenerate its brain. A brain! Mammals in their embryo or juvenile stages can regenerate, too. For example, human children can regenerate fingertips, and infants can regenerate heart tissue, which means adults, too, might retain the crucial genetic code for regeneration. This opens the door to potentially developing pharmaceutical therapies enabling humans to "grow" tissues and organs lost to injury or disease, instead of simply forming a permanent scar.

It could be used to heal all cartilage injuries in the future.

so you telling me, hypothetically and completely theoretical. if i were to act as a superhero and got shot, will my face grow back???

You’d probably be dead after loosing too much blood and ur brain would’ve been deprived of oxygen for too long.

i knew that much just jokin round

Ah I didn’t catch onto the tone. But the field of biotech/regenerative medicine is pretty cool. In 10-15 years well probably be able to use stem cells to grow new teeth and skin for burn victims.

Keep regrowing your parts and maintaining yourself after you reach high mileage.
