"To put it simply, it's 3D bioprinting."
After the Red Queen finished speaking, she sent a simulation image. First, the human organs were scanned and dissected from the inside out. The location of every cell was recorded. Then, the cells were cultivated separately using cell culture technology.
These cells were added to the 3D bioprinter as "bio-ink" and organs could be printed.
This technology was currently being done by many scientific research institutions on Earth. They had already successfully printed skin, ears, nose, and other organs. However, progress was limited when it came to blood, bone marrow, and internal organs.
Because these important organs were intricately constructed and had complex functions, mistakes could be made if one was not careful, so there was no major breakthrough yet.
Mr. L: "This is good, I need this!"
The group notification: "The Red Queen sent you an exclusive red packet."
Lu Zixin received the red packet. It contained information on the 3D bioprinter and related components, including in vitro cell culture, organ scanning, and so on.
…
At the Biotechnology Research Institute of the City of Future in Hongxin, Lu Zixin asked people to form a team to prepare for the 3D bioprinting research. The first experimental goal was to print the bone marrow of the little girl, Zhang Yan!
Before the experiment, Hong Xin had specially reported the results of the experiment. This kind of experiment was not something that could be done just because one wanted to. It had to be reviewed by the relevant institutions, especially when it came to experiments involving human organs. It might encounter scientific and ethical issues, so it had to be done carefully.
The approval was approved. The 3D bioprinting experiment was limited to in vitro human cell culture and organ printing for medical purposes. It was not allowed to carry out any other experiments on human bodies or that violated scientific and ethical standards.
After the report, the patient's guardian had to be notified and their consent was obtained.
In the ward of the Hongxin International Hospital, the little girl, Zhang Yan, was getting weaker by the day. Even speaking became difficult.
The frequent treatment had seriously overdrawn her body's functions. Her once lively eyes had now become hollow, like those of an old person who was about to die.
In the attending doctor's office, the attending doctor was discussing an important matter with her adoptive parents.
"With Zhang Yan's condition, if she doesn't undergo a bone marrow transplant, she will probably last two months at most." The attending doctor tried to speak in a calm tone, but Zhang Yan's adoptive mother could not help but tear up. Although they had expected this outcome, it was very sad to see their child suffering.
"Doctor, we have tried our best to find his adoptive parents, but …" Zhang Yan's adoptive father sighed helplessly.
"I know. This kind of thing can't be forced," the attending doctor said. "As doctors, we want the patient to recover the most."
"Now, there is another way. I don't know if you are willing to give it a try. Let me say this in advance. This method is very risky, so risky that the outcome is unimaginable! Do you understand? "
"What is it? No matter what it is, we are willing to try!" Zhang Yan's adoptive mother immediately said. Now that they were at their wit's end, as long as there was a glimmer of hope, they wanted to try.
"It's like this." The attending doctor explained, "Now, our Hongxin Biotechnology Research Institute is researching a new medical technology, 3D bioprinting. In short, it is to use 3D printing technology to create artificial organs outside the body. "
"3D printed organs?" Zhang Yan's adoptive parents were a little surprised when they heard this. Could medical technology be used in this way?
"Let me explain in more detail," the attending doctor said. "We are using this new technology to print a brand new bone marrow for Zhang Yan. Because the cells were cultured from her own body, there won't be any foreign rejection reaction. "
"But! I want to emphasize that this is a new technology. Before this, no medical institution in the world has tried this experiment. The hospital can't guarantee the success rate of the experiment. "
"I can only guarantee that the whole process will be voluntary treatment. You won't have to pay a single cent. But we can't guarantee the results of the treatment. "
After the doctor said that, Zhang Yan's adoptive mother said directly, "We agree!"
"So quickly? Don't you want to reconsider? "the doctor asked again.
Zhang Yan's adoptive father said, "We have no other choice even if we don't agree. If there is a chance for the child to survive, we will blame ourselves for the rest of our lives if we don't try."
"We want the child to know about this and see what her choice is."
"Okay, no problem," the attending doctor said.
Zhang Yan's adoptive parents told her about this, but Zhang Yan didn't really understand it. Hong Xiaoxiao patiently explained it to her a few times before she understood and agreed.
"Xiaoxiao, if I recover, I will play with you every day!" Zhang Yan forced a smile and said.
Zhang Yan's guardian signed the agreement and the medical experiment officially started. Lu Zixin didn't have to worry about most of the experiment. Their research team had rich experience in cultivating cells. The only thing they had to worry about was whether the 3D bioprinter could replicate the perfect bone marrow and transplant it into Zhang Yan's body.
A month later, in the cell culture laboratory, the biomaterial ink made of various cells was loaded into the 3D bioprinter and started to print according to the structure of the bone marrow.
"It must succeed!" The researchers prayed silently.
If this was successful, it would be another leap for the medical world. With this technology, from now on, the problem of needing transplants or lacking blood could be solved.
The 3D bioprinter worked quickly. It "stacked" the cells according to the rules to form the bone marrow.
The biological researchers were paying attention to the real-time holographic projection. It would magnify the printing scene so that they could see the printing process clearly. If there were any mistakes, they could stop it at any time.
Fortunately, the printing process controlled by the quantum computer did not make any mistakes.
Whether it was inside or outside, the printed bone marrow was no different from the real human bone marrow. They just didn't know if the transplant would be successful. The researchers could wait, but Zhang Yan didn't have time to wait.
Outside, in the operating theater, the skinny Zhang Yan was lying on the operating table, waiting for the bone marrow transplant. The newly printed bone marrow was sent in and the transplant began.
The chief surgeon took a deep breath, looked at the time, and said softly, "Begin!"
In the operating theater, the nervous and busy operation began. Outside the operating theater, the people waiting were even more nervous. There was the 3D bioprinter research team, Zhang Yan's adoptive parents, Lu Zixin, Hong Xiaoxiao, and the rest. They were all silently praying for Zhang Yan, hoping that the operation would be successful.
