Logan's ability to restore his wounds is real, but not as dramatic as in the movie

Regaining limbs, even reconstructing the heart or brain is . possible.

Wolverine's name is certainly no stranger to people who love movies, comics or not. He is a powerful warrior, a scheming strategist with his own healing power and an indestructible adamantium metal skeleton.

The final chapter of the series about Wolverine named Logan, still talking about that powerful warrior, but now, he is old and the ability to recover the wound has already gone away. Not once, on the screen appeared such a tired and weak X-Man.

But temporarily disregarding the character's private life, let's focus on one of the most typical power of this "old man" - the ability to quickly recover itself . What forces Wolverine to live more than a hundred years old, through countless battles, allows Wolverine to fight against all kinds of illnesses whether it really exists and what science is behind it?

Self-healing ability

I have seen countless times Wolverine survived the bullet shot without any damage, even using muscles to push the bullet out of my body. In comic books, Wolverine has lost many parts of his body many times but he can still recreate them.

In fact, every animal has the ability to restore itself on its body, but usually only to a limited extent. For example, the human liver has the ability to restore itself or the Anolis lizard species can shed their own tail to distract the enemy, and then grow new tail instead, is there a new tail? Standard as original.

Some animals are more capable of self-healing, with endless regeneration potential. One such species is the newts and Mexican salamanders. They have the ability to regenerate a broken leg, or can even replace extremely important internal organs like the heart or brain.

So why are there only a few species that have this ability, but not every species? Isn't it so great to self-repair a wound to regain the part? Essentially not so, although useful as resilience is not a very reasonable survival strategy.

The restoration of a wound is a trade-off between how fast recovery is and how well it is able to recover. For complete recovery it will take time; Immediate recovery of open wounds will reduce the likelihood of excessive infection or bleeding, but will leave scars.

Animals use a fiber-linked protein called collagen to hold the cells together (so does the human body, one-third of our body contains collagen). These proteins are cross-arranged in normal tissues, while in open wounds, scar fibers are arranged in parallel with each other.

The scar is the stain on the sides of the tear mouth together.

Imagine the usual tissue like a big cloth, the scars are the tissue marks on the sides of the tear mouth together. Obviously, the patch is faster than embroidering the torn fabric, so it is obvious that the wound will be healed by itself and the wound is faster with a scar. That is why in the process of evolution, natural selection preferred the way to recover by scar.

Regrowth of body parts

Wolverine is not a superman (or mutant - gene mutants), Wolverine is a salamander, rather.

Most mature bodies are divided into different parts, with different tasks, such as the outer skin is a barrier to protect the internal organs for example. Self-healing turns these walls into stem cells, capable of division and gradual, self-healing into new skin, new bones, new muscles, new nerves and new (also) blood vessels.

When the body is damaged, the skin surface has open wounds, the outer protective layer forms a layer of "wounded epidermis", which releases growth factors to stimulate the cells around the stain. love. In the process, fibroblast cells - cells that make up collagen fibers - are the most important cells. The salamander is capable of "reprogramming" these fibroblasts to become blasteme - a pill of stem cells, to increase resilience. Perhaps Wolverine's body also has this mechanism, stronger.

Humans or mammals in general have not completely lost that incredible self-healing ability. Each year, deer can regenerate gauze (including skin, nerves and bones) and rats can recover punctures in their ears without scarring.

Self-healing ability is also stronger when tissues are younger. For example, children can recover their damaged fingertips, even re-creating fingerprints thanks to stem cells located at the end of the nail. A fetus can heal itself without scarring.

Not that humans CANNOT recover, but rather we chose NOT to recover. So how did Wolverine get that ability? Perhaps through genetic modification, he is not a "mutant".

And the ability to heal itself quickly

People usually take 18 years to reach the standard size, salamanders take several months to regain body parts, and Wolverine takes a few seconds to close the mouth of a bullet wound, accompanied by pushing the bullet out too. recovery process. So how did Wolverine recover so quickly? Perhaps he took advantage of the way cells stop themselves from dividing in an uncontrollable way.

Wolverine took a few seconds to close the bullet wound.

There are two types of genes that prevent this "bluff" cell division: proto-oncogenes and tumor control genes . Pre-gene proliferation often produces proteins involved in detecting developmental signs; The tumor control gene creates p53, a type that activates cell repair mechanisms if they detect lesions in the body.

According to stem cell researchers, normal cells not only use tumor control genes to stop cancer, it also has the ability to vary depending on the context, deactivate the gene to increase its ability. tissue self-healing ability. Wolverine probably controls the genes that control this tumor to function effectively.

To what extent is effective, it is time for that ability to disappear with age. It is no coincidence that time is the biggest enemy of humans - regardless of ordinary people or mutants. The warrior's quick and powerful resilience this year is gone: old man Logan was caught up by the enemy.
