Time is like a white horse passing through a gap, whether it is leisure or busy, it can pass by people inadvertently.

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

　　 Although school has not yet started, many postgraduate candidates have already returned to school early.

　　 The originally deserted campus has become enthusiastic again with the return of the students.

　　 However, since this month, the Chen Chen trio has been in dim darkness and has to work in the laboratory for more than ten hours a day.

　　 Eat breakfast at 8 o'clock in the morning and enter the laboratory at 9 o'clock. Except for going out of the laboratory for lunch at noon, it is already after 9 o'clock in the evening when I come out again.

　　 Sometimes it is too tired, Chen Chen and Wang Wei do not go back to school, and just spend the night in the lounge.

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

　　 Until three days after leaving school, the last batch of mice implanted with egg cells finally gave birth to cloned pups, and the preliminary work of the experiment was successfully completed.

　　 So Chen Chen divided the cloned mice into three groups.

　　 The first group is the brain injury model group, and the group is divided into two teams, AB.

　　 Among them, Team A will use artificially cultivated autologous stem cells for treatment, Team B will use cloned autologous stem cells for treatment, and the two teams will have four each.

　　 The second group is a spinal injury model group. Same as above. Team A uses artificially cultivated autologous stem cells for treatment, Team B uses cloned autologous stem cells for treatment, and the two teams have four each.

　　 And the third group has the largest number, a total of 20, all of which are specially selected elderly SD rats. They are used to rebuild the immune system.

　　 All mice in this group have been cloned and have cloned stem cells corresponding to them.

　　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.

　　 is the so-called bone marrow transplant.

　　 As for why there are so many third groups?

　　 That's because, just this process of radiotherapy and chemotherapy can kill most of these mice.

　　 The so-called radiotherapy and chemotherapy are treatments that use radiation and chemical agents to kill the cancer cell clusters in a certain position in the patient's body.

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

　　 This is also the reason why patients undergoing chemotherapy and radiotherapy will lose their hair.

　　Even, many patients with advanced cancer died not because of the spread of cancer cells, but because of the chemotherapy process that destroyed the patient's body. It must be said that it is a tragedy.

　　 Since cancer was formally discovered in 1911, the war between humans and cancer has lasted for hundreds of years.

　　 In this protracted war, human beings were helpless against cancer, to the subsequent radiotherapy and chemotherapy, to the various types of targeted drugs nowadays, little by little, they brought back their lost lives.

　　 And the advent of bone marrow transplantation, a treatment method, marked the first victory in the war between humans and cancer.

　　 This kind of victory will continue to spread until one day in the future, human beings will completely overcome the disease of cancer and let cancer disappear from human beings.

　　 is like smallpox back then.

　　 Of course, not every bone marrow transplant can be successful.

　　 The success rate of bone marrow transplantation, which is clinically recognized by the medical profession, for the treatment of leukemia is only 60%.

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

　　 Therefore, bone marrow transplantation is still a journey of confrontation between human beings and disease.

　　 If there is an improper operation in the intermediate link, which causes all the mice to die, it means that all the human and material resources in the past month have been wiped out.

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

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

　　 It's just that rats are different from humans after all. These chemotherapy methods are still too intense for mice. Chen Chen can only guarantee a 40% survival rate.

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

　　 Next is the formal experimental period.

　　 Five more days have passed, and it is officially the beginning of school.

　　 Chen Chen and the three submitted an application to the school to delay returning to school, and continued to nest in the laboratory day and night.

　　 At the same time, with the use of stem cells for treatment, both the first and second groups began to show signs of recovery.

　　 The third group is in a bad situation. Five of the twenty SD rats have died. Although the remaining rats are alive, they are still dying and even stop eating.

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

　　 But six are enough.

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

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

　　 The three-month trial period, which was once planned, has finally come to an end.

　　 At this moment, the three of them gathered together in front of a group of white mice, and each of them showed excitement on their faces.

　　 "Final result verification..."

　　 Chen Chen said to the recorder, "The number of team A in the first group of brain injury model group is 3, survival is 3, and the degree of cure: No. 1 is better, No. 2 is significantly better, No. 3 is slightly better..."

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

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

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

　　 "In the third set of experiments, 3 survived eventually. CT showed that the body functions of the experimental body that had been aging had 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, the cloned young stem cells are far more effective than the artificially cultivated autologous stem cells?"

　　 "Furthermore, the third set of experiments also shows that replacing the bone marrow can really restore people's 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 is also smiling, his eyes are very calm, "Next I will write two papers. As I said before, Xia Yin's first work, Viagra second work, and my corresponding author, there is no problem, right?"

　　 "No, I have caught the light of both of you~lightnovelpub.net~ If it weren't for you, Chenzi, the experiment would not have been so smooth."

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

　　 "This article is about the difference between the efficacy of artificially cultivated stem cells and cloned autologous stem cells on the human body. This article automatically covers the first and second sets of experiments."

　　 Chen Chen explained, "The other one is an experiment on bone marrow transplantation."

　　 "Also, the first group and the second group are more convincing together."

　　 Xia Yin smiled and nodded, "What about the submission? I must vote for a district, right?"

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

　　 Upon hearing this, Xia Yin and Wang Wei cheered again.

　　 "Which journal do you plan to submit?" Xia Yin asked.

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

　　Wang Wei answered first, "Did your tutor not teach you? The shorter the journal name, the more popular it is!"

"Cell", also known as "Cell", is a magazine about the latest research findings in the field of life sciences. It is undoubtedly the TOP of the TOP in the field of biology. The impact factor has not fallen out of the top three since the publication. It can be said to be engaged in life sciences. The faith of professional people.

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

　　 Chen Chen looked at the two extremely excited and laughed, "Viagra is right, he must have voted in "Cell", after all, it is faith."
