Galaxy Technology Empire

June 20th.

After several days of consultations with Wang Zhiqiang, Colombo announced the completion of the "Friendly Cooperation Agreement."

As Ceylon joined the Galaxy Consortium, Tianhan Security quickly established a security base in northern Ceylon and stationed the Sixth Mecha Team there.

With the establishment of this security base, the Galaxy Consortium has formed an area of ​​influence in the northeastern part of Tianzhu Ocean.

In this way, the safety of the Galaxy Consortium's waterways in Tianzhu Ocean has been greatly improved.

Life Sciences Group, Hive Australia.

Huang Junjie was operating a stand-in robot to visit the laboratory.

There are people living in each of the prison-like rooms, these are death row prisoners and the like.

Through the one-way glass window, Huang Junjie observed these people. Some were sitting with numb eyes, some were shouting angrily, some looked like they were doing nothing, and some were watching TV series.

"How is the condition of the experimental subjects?" Huang Junjie asked Kenji Takahashi expressionlessly.

"Chairman, there are 32 experimental subjects in total, and all of them are in good condition." Kenji Takahashi felt no guilt about using these prisoners for experiments.

Huang Junjie took a look at the holographic file: "Why are there only 30 people left on the survival list?"

"Two committed suicide." Kenji Takahashi spread his hands helplessly.

"Suicide?" Huang Junjie was noncommittal, and then carefully looked at their experimental reports. Due to the perfect organ cloning technology, no obvious excretion was found in the cloned organs produced by Kenji Takahashi and others in the 32 experimental subjects. Strange phenomenon.

The so-called rejection phenomenon simply means that autologous tissues exclude foreign tissues and organs, which is a post-transplant rejection phenomenon.

The phenomenon of rejection is that organisms may reject substances that are not their own. If type A blood is transfused into a person with type B blood, the person with type B blood will produce antibodies, which is a phenomenon of rejection.

Rejection often has extremely serious consequences, and in severe cases, it can be life-threatening.

In addition to blood transfusions, bone marrow, and even organs need to be transplanted. The biological indicators of the two must be extremely similar. Small differences may cause rejection after transplantation.

Mild rejection symptoms can be treated with drugs, and immunosuppressants are generally used to combat this reaction. However, there is no effective solution for severe rejection symptoms, which often endangers the life of the transplant recipient.

The advantage of cloning organs is that there is almost no rejection, because the cloned organs themselves are genetically identical to the original organs.

However, everything is not absolute, and rejection may still occur. For example, if a person's lungs develop lung cancer due to decades of smoking, when the lungs are replaced, the body may not be able to adapt to the new lungs. Rejection may occur. possible.

Of course, this probability is quite small. Even if this kind of rejection occurs, it can be eliminated through running-in treatment.

"Takahashi, are you doing universal cloning?" Huang Junjie asked after turning to the last part of the experimental report.

Kenji Takahashi nodded: "Dr. Michel is in charge of this, mainly to see if non-prototype organs can be cloned from other cells."

"How was the experiment?" Huang Junjie asked as he didn't see the results in the experiment report.

"Some cells can be completed, such as stem cells, and some have no results for the time being, such as heart cells and brain cells." Kenji Takahashi replied.

The so-called universal cell cloning means that any human organ or part can be successfully cloned using any human cell.

"Take your time, don't rush for quick success, we have plenty of time to study these things slowly." Huang Haojie said as he walked.

As they walked, the two of them arrived at the artificial blood laboratory that Zhao Zhangde was in charge of. Huang Junjie stopped Kenji Takahashi who wanted to notify him and walked directly into the laboratory.

Inside a clone's life-sustaining warehouse, it was undergoing rapid changes, and soon turned into bright blood red, but these were only red blood cells, and blood was composed of plasma and blood cells.

Plasma contains water, protein and low molecular substances, and there are a variety of electrolytes and organic compounds in low molecular substances. Blood cells include three types of cells: red blood cells, white blood cells and platelets. The average lifespan of red blood cells is 120 days, that of white blood cells is 9-13 days, and that of platelets is 8-9 days.

The lifespan of blood cells affects the retention time of blood. Currently, there are generally two storage methods:

The first is the freeze-drying method [purifying various components in fresh blood and rapidly freeze-drying them in a special machine. The corresponding blood components can be preserved for a year, and a special thawing solution is used to dissolve them within a specified time. , infused into human body]

The second type of whole blood preservation [is the kind used in street blood donation carts, which are special disposable blood preservation bags that contain anticoagulant ingredients and nutrient solutions. Blood can only be stored for one month]

In addition, in addition to the main components of plasma, blood cells, and genetic material, blood also contains various nutrients, such as inorganic salts, oxygen, cell metabolites, hormones, enzymes, and antibodies.

All of these things will have a certain impact on the research and development of artificial blood.

Zhao Zhangde, who was concentrating on the experiment, didn't notice Huang Junjie walked in, and was still doing the experiment on his own.

They are cloning red blood cells, white blood cells, and platelets separately, and then adding other substances to prepare artificial blood.

After a while, Zhao Zhangde shook his head. The white mouse in his hand showed obvious rejection.

"Is it a matter of proportion or something else?" Huang Haojie asked.

Zhao Zhangde was stunned for a moment and then said: "Well...it turns out to be the chairman. We have encountered some small troubles. This blood preparation ratio needs to be tested for a while."

"Is the rejection very serious?"

"It's not too serious. We adopted the dry-freezing method and can quickly produce universal blood. However, there are still many people whose blood cannot be used as universal blood." Zhao Zhangde explained.

Because a small number of humans have panda blood, and it would not be cost-effective for hospitals to have these blood types on a regular basis. Zhao Zhangde and the others hope to build a rapid blood production machine.

In this way, the rejection phenomenon of universal blood can be solved. This is not just a problem of panda blood, because even if the blood types are the same, if the blood is not your own, there will be adverse reactions if too much is transfused.

If a rapid blood production machine can be developed, it only needs to collect a little blood from the patient, and then clone it in large quantities to produce as much as it needs. In this way, the hospital will not have to spend money to preserve the blood, and the patient will not have to search for the corresponding blood type and worry about rejection. Phenomenon.

"After the system is integrated, is it likely that the blood produced will have differences in component concentration?" Huang Haojie knew the problem at a glance.

"Chairman Gao Jian, this is the problem. We are currently discussing the relevant situation with the Computer Research Institute. We hope they can adopt a suitable operating modulation system. After all, if something goes wrong with this kind of thing, people may really die." Zhao Zhangde nodded. replied.

Huang Junjie encouraged Zhao Zhangde and others, and visited Michelle's universal cell cloning laboratory. Her progress in this area was also so-so.

However, now that cloned organs are almost practical, Huang Haojie has ordered the Life Sciences Group to announce the cloning of organs at a selected date and recruit volunteers willing to participate in cloned organ transplant operations.
