Chapter 180: Blood manufacturing method

phone-reading
After seeing them say Zhou Yunsheng, she said directly, "I don't understand what you said. Let's go and see how blood is made."
She looked at Du Xianyu again and asked, "Director Du, have you applied for the blood products we know to the Food and Drug Administration?"
"I informed Wang Tong that he sent someone to take the sample and said that he wanted to apply to the Food and Drug Administration. I didn't ask in detail how long it took to get the results." Du Xianyu simply replied.
"Oh, why didn't I receive the message. According to the procedures prescribed by our company, they should report it, and I should receive the message as soon as possible. They will not notify me, and the mobile phone software of the Food and Drug Administration will also notify me." Zhou Yunsheng Strangely said.
She also took out her phone and opened the cloud intelligence platform. After reading it, he said calmly: "It turned out that they are in the process of applying and have not yet officially submitted for approval. This product is no longer on the priority list and needs to be queued."
After Zhou Yunsheng finished speaking, they wanted to go to the place where blood and its blood products were made.
It can be seen from Du Xianyu's words that blood manufacturing technologies are now mature and can be industrialized at any time.
Led by Du Xianyu, they followed the glass corridor of the biological laboratory. Go to the laboratory responsible for manufacturing blood and blood products.
Li Hao saw them across a transparent glass wall and could easily see the scene in the laboratory.
There is nothing special in the laboratory except that there are many large glass culture tanks inside. Most of the liquid in the jar is colorless and transparent. Only two large jars are the most special, one is dark red and the other is pale yellow.
An experimenter who just wanted to enter the laboratory saw Du Xianyu and Li Hao standing here, came over and greeted them.
The experimenter holds a glass box with slow experimental materials in his hand and wants to enter the laboratory.
He went up to the glass room next to him and put on the protective clothing he was wearing, and then the ceiling of the glass room lit a blue-violet light.
Zhou Yunsheng looked at curiosity and asked Du Xianyu: "Is this how they kill viruses?"
Du Xianyu introduced her: "This is sterilized by high-intensity ultraviolet rays and electrostatically dedusted. Ensure that no pollutants enter the laboratory."
Zhou Yunsheng stared at the way blood was made in the laboratory. She pointed to the laboratory and said, "This looks simple, and I see that their operation is not complicated."
"It is very simple to look at, but the technology contained in it is very complicated. We also found the best ratio after tens of thousands of experiments.
Blood is no better than other substances. It transports oxygen, nutrients, and waste products that the body needs.
A slight difference in the composition of each component will cause the rejection reaction of the organism. The most severe rejection is to drain the blood immediately and replace it. The mouse died a few minutes later.
The core technology of our blood is the ratio of various components, which is more important than hematopoietic stem cells.
In particular, we should also consider the storage time of the blood, add our special additives, and do not affect the efficacy of the blood, the best time to save it.
Now that we produce blood, it can be stored for about 60 days. "
Li Hao saw the large jars packed in the laboratory. He did not quite understand the way blood is made, and asked Director Du: "Director Du, you can simply talk about the way blood is made."
Du Xianyu pointed to the equipment in the laboratory and said, "We also use the principle of bionics to model the generation of blood in living organisms.
We started with highly viable cells obtained from organisms. Using certain technical means, it is induced to differentiate into hematopoietic stem cell progenitor cells.
Such progenitor cells are cells produced by the embryo in about ten days. It has a high degree of differentiation ability and can not only differentiate into blood-related cells.
It also has the function of differentiating into lymphocytes. It's just that the human immune system is too complicated, it is a very delicate system, and a little error has a great impact on the human body. We have not yet found the role of lymphocytes.
Hematopoietic stem cell progenitor cells are then differentiated into hematopoietic stem cells. Hematopoietic stem cells differentiate into red blood cells, white blood cells, platelets and other blood cells under certain conditions. "
Du Xianyu pointed to the red glass jar and said, "This is where the red blood cells are cultivated. The cells we cultivate are basically not much different from the cells in the human body. After animal experiments, they can transport oxygen."
He pointed to the pale yellow culture tank and said, "This is plasma, which is pale yellow because of the bilirubin inside. Plasma configuration is the most difficult for us.
As long as the blood cells fix the hematopoietic stem cells, the rest is a natural task.
Plasma is extremely difficult to configure, and everyone's plasma composition is slightly different. We can only find the largest common divisor to ensure that plasma will be safe and stable in any human body.
About 90% of it is water, and there are some trace elements and various proteins in it. When other substances are lacking in the human body, they will naturally be produced.
In addition, there will not be any people whose blood is completely drained and alive. So less substance will not affect its effect.
Plasma and blood cells are mixed together at a certain ratio ~ EbookFREE.me ~ is our artificial blood. "
Du Xianyu sighed, and continued: "Our artificial plasma can only replace two-thirds of the blood at most. It has many trace components that we have not yet studied.
We experimented with mice and drained the whole body of blood to replace the blood we made. After that, I can still lead a normal life, but I feel debilitated and not lively at all.
After experiments with various animals, we found that when artificial blood is replaced to 80% of the whole blood, the organism will have side effects. "
Zhou Yunsheng looked at this blood manufacturing laboratory. She always had a question. After hearing Du Xianyu's words, she immediately asked: "Director Du, we have six blood types. I think this big jar has only one blood type. How patients use it. "
"There are 34 blood types in the human body and we have arranged them in other laboratories. Hematopoietic stem cells are prepared for each blood type.
The main blood group detection methods are ABO and RH, but the confusion of other blood types can also have adverse consequences for people.
This technology starts from manufacturing, we strive to be comprehensive, to ensure that each blood type can produce enough blood. "
Zhou Yunsheng covered his mouth and said, "Humans have 34 blood types. I always thought that they were ABO and RH."
After they visited the blood manufacturing laboratory, Li Hao and they separated from Du Xianyu. Du Xianyu went on to inspect the progress of each laboratory.
Zhou Yunsheng took Li Haoben to the medical team. She said she would go to the ophthalmologist Dr. Qian Minghua and help Zhou Yuanyuan inquire about the condition of the eye transplant.
He also took Li Hao to the old Chinese medicine doctor Li Deren, saying that Li Hao has been in poor health recently. Coincidentally, the company has a good old Chinese medicine practitioner who wants to nurse him well.
