Didn't you hear those people outside call her a little fairy?

If Fan Xin made a move and restored his original life, he must also have the hope of surviving Gu Yao to regain his strength, right?

Gu Fanxin looked at the eager Zhang Minyi in front of him.

Alas, I really don't know it. However, the regeneration of severed limbs has not been successful so far.

Li Yuanbao, that guy can be regarded as blessed. At least there was a girl who was thinking about him.

"Crabs will grow out when their legs are broken, do you tell me whether human limbs have the ability to regenerate?" Zhang Minyi asked impatiently.

Gu Fan was stunned.

Geckos can regenerate after their tails are broken, crabs are broken feet, and earthworms can be regenerated after being broken.

Can it be applied to the selection and replacement of severed limbs and organs in the human body, for example, if a person's hands and feet are crippled, can the wound be simply amputated and genetically engineered, so that it can slowly grow into a hand or a foot?

Indeed, when a crab is frightened, it will automatically give up its caught foot and run for its life.

However, there is a certain place to break from the place, and the breaking point is between the basal ganglia and the rotor of the foot that has a special structure that prevents the wound from bleeding.

When the gecko's tail is held down by an enemy, it will twist violently, break its tail by itself, and escape.

The mystery lies in the fact that each of its tail vertebrae has a smooth "self-harming" articular surface, and the muscles, skin, and scales connected to it are relatively loose.

The wound at the severed tail heals quickly, forming a tail bud base, and after a period of cell division and proliferation, an unpleasant regenerative tail grows.

Similarly, the cephalopod mollusk octopus, when a tentacle is tightly bitten by an enemy, it will also contract forcefully, so that the tentacle will break off, the wound blood vessels will contract violently, close on its own, and after a few hours, it will be unobstructed again, and the wound will heal the next day and begin to grow new tentacles.

The annelid earthworm has a more peculiar ability to regenerate, and where it is cut off, it will give birth to new embryonic tissue that can quickly compensate for the lost part.

Cutting off the tail is faster than cutting off the head to regenerate, and the young ones regenerate faster than the old ones, the key is whether there are nerve cords in the limbs, if they are completely removed, there is no chance of regeneration.

The coelenterate polyp is cut into several small segments, each of which can grow into a small polyp, and even if the lip of the polyp is cut from the mouth, it will actually grow into a two-headed monster polyid.

Throw the echinoderm starfish into a few sections and throw them into the sea, each of which can grow into a complete starfish.

It can be seen that the lower the animal species, the younger the age, the stronger the regenerative ability, and in comparison, the lower animals have many more nerves in their limbs than the human body, so they will heal faster after injury.

The severed limbs of geckos, crabs, and octopuses almost all occur in specific parts, which has become a self-preservation instinct for animals to adapt to survival.

After a person or other animal is seriously injured such as a severed hand or foot, the body will give instructions to heal the wound, and then you will heal at the wound, and no new hands or feet will grow, but lobsters and crabs will have new limbs after the limbs are severed, and the instructions issued by the body are to grow new limbs, so there is regeneration.

It seems that if human beings want to regenerate severed limbs, they must also start with genetic engineering.

Fortunately, during this time, the Tissue Engineering Research Center of the Medical University planted the cells of the required organs on a special material, and after culture and multiplication, they could be made to form the required human organs.

Experiments have shown that cell-cultured tissues do not grow indefinitely and do not shrink.

This also brings hope for the repair or reconstruction of human bones, trachea, liver, joints, skin and other organs.
