I Have A Super USB Drive

　　 "Rebuild the immune system?" Wang Wei looked dazed.

　　 "Do you know what is the most effective clinical treatment for leukemia now?" Chen Chen asked back.

　　 "Uh, I haven't paid too much attention to it. This should be biomedical knowledge." Wang Wei scratched his head.

"In simple terms, leukemia is a type of hematopoietic stem cell pathological disease. For some reason, the human hematopoietic stem cells have undergone malignant proliferation, thereby inhibiting the normal hematopoietic function of the human body. It is similar to the principle of cancer, so it is also called 'Blood cancer'."

Chen Chen explained, "The most effective way to treat leukemia in the medical community today is to pair bone marrow, select a volunteer with the closest genetics to the patient, and then the patient will receive chemotherapy and radiotherapy to kill the hematopoietic stem cells in the bone marrow. "

　　 "The volunteers will then be injected with a drug called a'mobilizer' to promote the growth of hematopoietic stem cells in the bone marrow and release them into the blood. The hospital will then collect these stem cells and inject them into the patient's body."

"Because the hematopoietic stem cells in the patient's body have been killed before, there is a niche in the patient's body. The newly injected hematopoietic stem cells will produce a kind of'homing' effect and spontaneously enter the patient's bone marrow. Rebuild the patient’s immune system within a month."

　　 Chen Chen concluded: "And this is called bone marrow transplantation. The healthy hematopoietic stem cells of volunteers are used to replace the diseased stem cells of the patient. In fact, the so-called bone marrow is not real bone marrow, but only hematopoietic stem cell transplantation."

　　 "What does that have to do with your experiment?" Xia Yin asked impatiently.

　　 "My third experiment is to select a group of aged rats, clone them, and extract young hematopoietic stem cells and mesenchymal stem cells from the clones."

　　 "Then, just like treating leukemia, kill the hematopoietic stem cells and mesenchymal stem cells of these rats and replace them with cloned stem cells."

　　 Chen Chen thought, "If it succeeds, will this rat, which had been dying and aging, regain its youth?"

　　 "Should it be impossible, right?" Xia Yin showed a shocked expression.

　　 "Why is it impossible?"

　　 Chen Chen’s mouth raised a slight curve, “Mesenchymal stem cells have the ability to differentiate into muscle cells, hepatocytes, osteoblasts, fat cells, chondrocytes, stromal cells and other cells.”

　　 "Why does the human body age? It is because of the functional decline of human muscles, bones, and internal organs, but why does the human muscle, bones, and internal organs become functionally aging? That is due to the aging of stem cells."

"Young people’s stem cells can continue to replicate, replacing aging muscle cells, bone cells, and visceral cells, so young people’s metabolism is much faster than adults, but when humans reach the age of thirty, stem cells will age and replicate. The rate of replacement gradually cannot keep up with the aging rate of the cells themselves, so the human body will also show signs of aging..."

Chen Chen said, "So, if the human body's mesenchymal stem cells and hematopoietic stem cells can return to youth, can the human body also return to youth? Even if the other internal organs cannot return to youth, it is muscle, bone, hematopoietic function, etc. Part of the body's functioning to regain youth is something that many people can't achieve, right?"

Hearing this passage, Xia Yin immediately showed a thoughtful look. After all, she is already a senior, and has a wider range of knowledge than Wang Wei. She also understands better than Wang Wei that this experiment, if successful, will affect the modern age. What an impact the medical world has caused.

　　 "If it is really successful, this kind of result would be enough to vote for a district." Xia Yin showed longing.

　　 "I have contacted Mengan Pharmaceutical Company, and can use their channels to help us purchase experimental drugs. I asked about the price, which is absolutely fair and just."

　　 Chen Chen added, "We can start the experiment today."

　　 "Then let's set off now." Xia Yin agreed, "Start the experiment early, maybe it can be completed in three months!"

　　 The three people set off immediately and took a ride to the building of the Meng'an Pharmaceutical Company. The Mediterranean man who had visited Chen Chen and Xia Yin also waited for a long time.

　　 Only a few days away, the Mediterranean Sea above the Mediterranean man's head seems to be wider.

　　 "You are finally here, if you don't come again, the leader will scold me to death."

　　 The Mediterranean man smiled bitterly, "At the beginning, we shouldn't have agreed to your conditions for calculating rental time after the winter vacation. We lost more than a week in vain."

　　 "Have you bought everything?"

　　 "I bought it. I bought the head-mounted experimental recorder and various experimental drugs. I have moved you to the fifth floor."

The Mediterranean man took out three magnetic cards and handed them to Chen Chen, "This is a laboratory access card. We will send someone to the laboratory for inspection once a month in the future. If there is any damage, please pay at the price. I hope you can take good care of our laboratory equipment and avoid contamination. lab environment."

　　 "Of course." Chen Chen took the magnetic card.

　　 "And this." The other party took out a business card again, "This is the source contact of our laboratory. If you are short of experimental drugs and experimental animals, you can call this phone to purchase."

　　 Chen Chen took the business card, which showed a person from the Shangdu Animal Experimental Research Center, and handed it to Xia Yin.

　　Because all the agreements have been signed before, UU Reading www.uukanshu.com therefore sent Chen Chen to the fifth floor, and the Mediterranean man left.

　　 "The entire floor is the laboratory you rent?"

As soon as Wang Wei arrived on the fifth floor, he wandered around, feeling this and that with a face full of novelty, "This is too extravagant, it is better than the laboratory environment of the school. By the way, where does the GMP laboratory come from? See the entrance?"

　　 "It's in the basic laboratory."

Chen Chen put on disposable slippers and walked into the basic laboratory. "The blue alloy door in front is the entrance, and there are two compartments behind the basic laboratory. I asked them to buy three beds and put them inside. Used as a lounge."

　　 The two followed, and they saw a large pile of items in the basic laboratory, including three folding beds.

　　 In addition, there are various encapsulated chemicals. These drugs want to be transported into the clean area. I am afraid that the three of them will be busy for a while.

As students of the College of Biological Sciences, none of the three of them entered the sterile laboratory for the first time. They still knew the relevant procedures. Wang Wei was responsible for transporting the medicines into the buffer corridor, Xia Yin was responsible for putting them in the delivery window, and Chen Chen Responsible for receiving in the GMP laboratory.

　　 As the three of them get busy, they can divide the work for a while and do their own things in an orderly manner.

　　 But before waiting for a while, the elevator door opened again, and a person pushed a small cart of sterile boxes and walked in.

　　 "This is what you call an SPF laboratory animal, right?"

　　 "Yes." Wang Wei was responsible for delivering the medicine to the outside world. At this time, he immediately notified Xia Yin to come out and sign the experimental animals.

　　 These experimental animals are sixty SD rats and ten experimental rabbits. After a simple handover, the two settled these animals into the animal breeding room.
