Chapter 212

Zhang Wei took half a tube of blood from Jiang Shan and arranged an intelligent robot to send Jiang Shan home. Considering Jiang Shan's great help to him, he also gave Jiang Shan a diluted gene evolution liquid, which will be injected by the intelligent robot to Jiang Shan's father himself. If there is no accident, Jiang Shan's father should be able to wake up after receiving the injection.

Zhang Wei also specifically asked Jiang Shan not to divulge this matter. If someone asked about it, he said that his father was awake. In addition, the matter of self-healing ability also needs to be kept secret.

After Jiang Shan was sent away, Zhang Wei handed Jiang Shan's blood to Beidou for testing, and analyzed which genes had led to Jiang Shan's super self-healing ability. In addition, in-depth experiments should be carried out to determine the extent of Jiang Shan's self-healing ability, whether it can only recover the wound or go further to achieve limb regeneration. Of course, the subjects must be mice. Zhang Wei is not cruel enough to use Jiang Shan to do this kind of experiment.

After that, Zhang Wei began to think about his ability to regenerate.

In fact, in addition to using genetic technology to make the body have the ability to regenerate, there is another way, which is to create human tissues such as hands, feet, hearts, kidneys, and then transplant these human tissues to the human body.

The first step is to make human tissues such as hands, feet, heart and kidney by technical means. This technology has appeared and is developing rapidly. This is 3D bioprinting.

Different from the well-known 3D printing technology for industrial manufacturing, 3D biological printing technology (academically known as biological additive manufacturing technology) is a new regenerative medical engineering technology that integrates materials science, cytology, engineering, 3D printing and other disciplines and fields. First, the CAD data model is processed by computer, and the three-dimensional model is divided into several two-dimensional layers. Then, the active materials such as cells or biological building blocks are used as raw materials, and the materials are accumulated layer by layer according to the two-dimensional layer to reconstruct the biological products such as human tissues and organs.

As for the raw material of 3D bio printer, it is called "bio ink". Researchers extract stem cells from human bone marrow or fat and make them differentiate into different types of other cells by biochemical means. Then, these cells will be sealed into "toner". When starting 3D bio printer, the "toner" will gather in the pre-designed part through the print head On the other hand, the rudiments of the printing organs appear gradually.

At present, a 3D biological printer has been produced in China, which can produce 10 cm long blood vessels in 2 minutes. The next goal is to print out bones, ears, nose, liver, kidney, heart and other organs, and the ultimate goal is to print a new body. This is the man-made man, but the man-made man created is not much different from a "walking corpse", but as long as the consciousness implantation technology is invented, "walking corpse" can become a puppet controlled by the manufacturer, as long as the order is given, he will not hesitate to do anything, including killing and suicide!

It can also be seen from this that science and technology are a double-edged sword. If this technology is used in the right place, it can make people easily replace damaged heart, kidney and other body parts, have a healthy body, and also can end the gray industry of human organ trade. Because with the birth of this technology, organs that are originally more expensive than real gold will be unprofitable Run, the gray industry will disappear naturally, so you don't have to worry about waking up with no kidney.

However, if this technology is used in the wrong place, it will be quite terrifying, because it can be used to make man-made troops and lead wars to evil ways. In addition, as like as two peas! If even the technology of consciousness reproduction and implantation has been invented, the printed person can have the same consciousness as you, that is to say, he can perfectly replace you and have everything you have, including wealth, parents, friends and wife! If the people who master these three technologies at the same time have enough ambition, they can also implement the "replacement plan". If they want the wealth of a listed company, it's very simple to print out the shareholders of the company, implant awareness, and then find opportunities to "replace"; if they want to control a country, it's no problem to print out the power holders of the country's political and military circles, and plant them Become aware and then look for opportunities to "replace.". Although the process is not as simple as described, as long as careful planning, there is a great chance of success. So it's terrible to say that ambitious mad scientists.

However, the current 3D bioprinting technology is far from perfect, and there are many defects. For example, the printed tissue like structure is similar, does not have the function of organization, and cannot survive for a long time. Because even seemingly simple organizations face great challenges. Take skin as an example. It looks thin, but it has many functions. In addition to protecting the body, it also has the functions of feeling, warming, sweating, etc. if the printed skin does not have these functions, it will not work. As for the human body, it's a more complex system. Countless cells grow, heal and change in mysterious ways that we can't fully understand every day. We haven't decoded how cells are transferred. Although scientific research can put cells in the right position on the scaffold in perfect shape, no one knows exactly how to "start" seed cells.

However, Zhang Wei is confident in solving these difficulties. He has always been a man who breaks the limits and creates miracles. And to be honest, he is very interested in this technology, but he has been busy with this and that, forgetting this technology, until now, he just remembered it.

As for the second step, i.e. transplanting the manufactured human tissue to the human body, it is not difficult. Kidney replacement and heart replacement are very common, and even head replacement can be done.

As early as 1908, a surgeon in St. Louis, Missouri, created the world's first double headed dog by surgical transplantation, which grafted the head of one dog onto the neck of another dog; in the 1950s, surgeons from the Soviet Union and China cooperated to complete the operation of dog head transplantation, and finally the dog survived for 29 days.

On January 21, 2016, Chinese scientists successfully connected the blood supply between the monkey's head and the new body, but failed to connect the bone marrow nerves of the two. Because the bone marrow nerves failed to connect, the body part below the monkey's neck was paralyzed. In 2017, Sergio cannavillo, an Italian neurosurgeon expert, cooperated with the Chinese medical team to carry out the world's first human head replacement operation in China, which transplanted the head of a man suffering from spinal muscular atrophy to another body and achieved preliminary success. But after the operation, the man's quality of life was not high because of severe rejection. Moreover, there is still a lot of controversy about the operation, because the operation requires a "volunteer", which is not only highly controversial in ethics, but also causes some people to worry about whether my body will become a "volunteer" accidentally if it is looked upon by others, and then the body will become others'. Think of such a huge organ smuggling chain. This kind of thing is likely to happen. At that time, not only the single way people will be knocked unconscious to remove their organs, but groups of people will be missing.

However, if 3D bioprinting technology is mature, this problem can be solved perfectly, because 3D bioprinting technology can print the body without any rejection reaction. In addition, this new body can be customized. The body and height can be customized according to their own ideas. If you want to have an F cup and a 30 cm cup, there is no problem!

After careful consideration, Zhang Wei decided that he would study the two different kinds of regeneration capabilities at the same time, because both technologies are very useful. In addition to studying these two regeneration abilities, he also studied the mysterious meteorite.

……

When Zhang Wei determined his next research direction, people all over the world cheered happily, because in the first people's Hospital of zhongyun City, there has been a late cancer patient who has been injected with "future gene 2 injection liquid", and his vital signs have completely recovered. Then, famous doctors from all over the world carried out a number of tests on the patient, and finally unanimously confirmed that the patient with advanced cancer has recovered!

One doctor's representative solemnly announced to the present media reporter, "patient Zhang Xiaojun, lung cancer stage 4, multiple bone metastases in the whole body, metastasis in both lungs, tumor size of 28x40mm, bone damage at bone metastases, pathological fracture of the left three ribs

Seven hours after the injection of "future gene 2 injection ~ solution", all vital signs returned to normal, and cancer cells could not be detected

After comprehensive examination and evaluation by a panel of seventy-five medical experts on the scene, it was unanimously confirmed that Zhang Xiaojun, the patient, had recovered after receiving the injection treatment of "future gene 2 injection liquid"

The Internet is boiling at once.

"The" future gene 2 injection ~ liquid "is effective! There has been a late cancer patient cured, note that it is a late cancer patient, who was given a death notice by the doctor, saying that he will not live for two months! "

"Good thing! I can smoke and drink at ease. I'm not afraid of lung cancer and liver cancer any more! "

"It's really as simple as treating a cold. It only takes seven hours. It doesn't have to be so fast! Zhang Wei is a real bull! "

"Mom's egg, I was diagnosed with cancer last month. It's still in the late stage. I'm scared to death. In this month, I can't sleep if I don't have a good appetite. I went to buy cyanogen - potassium, but I can't lay hands on myself! Now I can finally sleep safely! "

"I lost a lot! I found out two months ago that it was in the late stage, and then I bought a lot of commercial insurance, trying to find a suitable opportunity to 'make' an accident and die together, leaving some pension money for my parents! It's nothing! "

"You should be happy upstairs. After all, people can survive, and there are infinite possibilities."

"It's right. It's better to live than to die. Hahaha! Suddenly I feel so happy that I can't feel the despair and depression any more! I'm going to run naked at 12 o'clock this evening, and I'm going to shout out, "get out of here, Ma Jun!"

"Get out of here, swollen ~ tumor Jun! Stay in line downstairs! "

"Get out of here, swollen ~ tumor Jun! Stay in line downstairs! "

……

The media all over the world are urgently covering this matter.

CCTV News Channel: "audience, here is an exciting news report. At two o'clock this afternoon, a phase I clinical trial of" future 2 gene injection liquid "developed by Zhang Wei, a famous scientist in China, began. Two hundred advanced cancer patients from all over the world
