I Have A Super USB Drive

Time is like a white horse passing by, whether it is leisure or busyness, it can pass by inadvertently.

In the blink of an eye, the new year has passed, and the time has come to the 2221 year of the Earth Federation.

Although the school has not yet started, many postgraduate students have already returned to school ahead of schedule.

The originally deserted campus became warm again with the return of the students.

However, over the past month, Chen Chen's trio have been working in the lab for more than ten hours a day.

I eat breakfast at 8:00 every morning and enter the laboratory at 9:00. Except that I will go out of the laboratory at noon to have a lunch, it is already after 9:00 pm when I come out again.

Sometimes they were too tired, so Chen Chen and Wang Wei didn't go back to school, and just spent the night in the lounge.

Xia Yin's work is more logistical, such as buying food, delivering water, and taking care of experimental animals, which is much easier than the two of them.

Three days before leaving school, the last batch of mice implanted with egg cells finally gave birth to cloned cubs, and the preliminary work of the experiment was successfully completed.

So Chen Chen divided the cloned mice into three groups.

The first group was the brain injury model group, and the group was divided into two groups, AB.

Among them, Team A will use artificially cultivated autologous stem cells for treatment, and Team B will use cloned autologous stem cells for treatment. The number of each team is four.

The second group is the spinal injury model group. Same as above. Team A uses artificially cultivated autologous stem cells for treatment, and Team B uses cloned autologous stem cells for treatment. Each team has four animals.

The third group had the largest number, twenty in total, all of them were specially selected aged SD rats, which were used for the experiment of rebuilding the immune system.

All mice in this group had been cloned and had their own cloned stem cells.

They will be used in the form of radiotherapy and chemotherapy to kill most of the hematopoietic stem cells and mesenchymal stem cells in the body, and then injected into the cloned stem cells to test whether they will return to youth.

Also known as a bone marrow transplant.

As for why there are so many third groups?

That's because most of the mice were killed or injured in the course of radiotherapy and chemotherapy alone.

So-called radiotherapy and chemotherapy are treatments that use radiation and chemical agents to kill a colony of cancer cells at a certain location in a patient's body.

However, this method of treatment has always hurt the enemy by one thousand and eight hundred by itself. After all, while killing the cancer cells, the normal cells in the patient's body will also be overwhelmed.

That's why patients with chemotherapy and radiation therapy lose their hair.

Even, many patients with advanced cancer die not from the spread of cancer cells, but from the chemotherapy process that destroys the patient's body, which has to be said to be a tragedy.

Since the official discovery of cancer in 1911, the war between mankind and cancer has lasted for hundreds of years.

In this protracted war, human beings have gone from being helpless against cancer, to radiotherapy and chemotherapy that appeared later, and then to today's various targeted drugs, bit by bit, regained the lost position of life.

The advent of bone marrow transplantation as a treatment method also marked the first victory in the war between humans and cancer.

This victory will continue to spread until one day in the future, mankind will completely defeat the disease of cancer, and cancer will disappear from mankind.

Just like the smallpox back then.

Of course, not every bone marrow transplant is successful.

Bone marrow transplantation, which is clinically recognized by the medical community for the treatment of leukemia, has a success rate of only 60%.

And among these 60%, half of the patients will relapse after half a year.

Therefore, bone marrow transplantation is still a thorny journey of confrontation between humans and diseases.

If there is improper operation in the middle link, all the mice will die,

It is equivalent to all the human and material resources in the past month.

After all, even the body is gone, what use are these corresponding cloned stem cells?

So, in order to accumulate experience in radiotherapy and chemotherapy of mice, Chen Chen deliberately took other mice to test the water.

However, mice and humans are different after all. These chemotherapy methods are still too intense for mice, and Chen Chen can only guarantee a 40% survival rate.

However, with the birth of the last batch of cloned mice, the preliminary preparations for Chen Chen's three experiments were finally completed.

Next, is the formal experimental period.

Another five days passed, and it was officially the day of school.

Chen Chen and the three of them submitted an application to the school for a delay in returning to school, and continued to stay in the laboratory day and night.

At the same time, both groups 1 and 2 began to show signs of recovery following the use of stem cells for treatment.

The third group was in a bad situation. Of the twenty SD rats, five had died. Although the remaining rats survived, they were dying and even stopped eating.

Two days later, the chemotherapy was completely over, and some of the dying mice were completely overwhelmed. Eight or nine mice died one after another, and only six survived.

But six is ​​enough.

Chen Chen now only hopes that two or three of the six can only last until the end of the experiment.

In this tense atmosphere, another month and a half passed.

The trial period, which had been planned for three months, finally came to an end.

At this moment, the three of them gathered in front of a group of mice, and everyone had excited expressions on their faces.

"Final result verification..."

Chen Chen said to the recorder, "The number of the first group of brain injury model group A is 3, 3 survived, and the degree of healing: No. 1 is relatively improved, No. 2 is significantly improved, No. 3 is slightly better..."

"The number of B teams in the first group of brain injury model group was 3, survival was 3, and the degree of cure: No. 1 was significantly improved, No. 2 was significantly improved, and No. 3 was significantly improved."

"Summary: The healing effect of group A using artificial stem cells is obviously inferior to that of group B using cloned autologous stem cells."

"The number of the second group of spinal injury model group A team is 4... The number of team B is 4, the same as above, regardless of the recovery speed and effect: group A is not as good as group B."

"In the third group of experiments, 3 animals survived in the end. The basic CT showed that the physical functions of the experimental subjects who were already in a state of aging have been greatly enhanced in all aspects..."

"I didn't expect that the three experiments were really successful!"

Wang Wei excitedly patted Chen Chen on the shoulder, "In other words, cloned young stem cells are far more effective than artificially grown autologous stem cells?"

"Moreover, the third group of experiments also showed that replacing the bone marrow can really restore youth?"

Xia Yin also murmured in a low voice, with a look of disbelief, "Chen Chen, we are going to be famous..."

Although Chen Chen also had a smile on his face, his eyes were very calm, "I will write two papers next, as I said before, Xia Yin's first, Viagra's second, and my corresponding author, no problem, right?"

"No, I got the light of both of you. If it wasn't for you, Chenzi, the experiment would never have gone so smoothly."

Wang Wei looked calm, and suddenly wondered, "By the way, why two? Isn't it three experiments in three groups?"

"One is about the difference between the effects of artificially cultivated stem cells and cloned autologous stem cells on the human body, and this one automatically covers the first and second sets of experiments."

Chen Chen explained, "The other one is the experiment of bone marrow transplantation."

"Yes, the first group and the second group are put together, which is more convincing."

Xia Yin nodded with a smile, "What about the submission? You must vote in the first area, right?"

"Of course, the first of these two research results may be a little overhang, but the second one is definitely no problem."

Hearing this, Xia Yin and Wang Wei cheered again.

"Then which journal are you going to submit to?" Xia Yin asked.

"There are only a few TOP journals in the first district of the biological field, and of course they are selected for "Cell"!"

Wang Wei answered first, "Didn't your instructor teach you? The shorter the journal name, the more popular it is!"

"Cell", also known as "Cell", is a journal about the latest research findings in the field of life sciences. It is undoubtedly the TOP of the TOP in the field of biology, and its impact factor has never fallen out of the top three since its inception. professional belief.

People who are engaged in scientific research often say "CNS papers". The CNS here is the abbreviation of the three top journals "Cell", "Nature" and "Science". These three journals are proud to publish papers.

Chen Chen looked at the two extremely excited people and laughed, "Viagra is right, he must have voted for "Cell", after all, it's a belief."
