"To put it simply, it's 3D bioprinting. ”

After the red queen finished speaking, she also sent a simulation drawing. First, the human organs are scanned and dissected from the inside out, the position of each cell is recorded, and then the cells are cultured separately using cell culture technology.

These cells can be added to the 3D bioprinter as "bioink" to print organs.

This kind of technology is also being done by many scientific research institutions on the earth today, and they have successfully printed skin, ears, nose and other organs, but for blood, bone marrow or internal organs, the progress is limited.

Because these vital organs are sophisticated in structure and functional, and they can go wrong if you are not careful, there has been no major breakthrough.

Mr. L: "That's good, I just need this!"

Group prompt: "The red queen sent you an exclusive red envelope." ”

Lu Zixin received the red envelope, which contained 3D bioprinters and related accessories, including in vitro cell culture, organ scanning, etc.

……

Hongxin Future City Biotechnology Research Institute, Lu Zixin asked people to form a team to prepare for 3D bioprinting research, and the first experimental goal is to print the bone marrow of the little girl Zhang Yan!

Before the experiment, Hongxin also deliberately reported the experiment. This kind of experiment is not something that can be done if you want to, and it also needs to be reviewed by relevant institutions, especially experiments involving human organs may encounter scientific and ethical issues, so you should be more cautious.

The approval opinion came down, and the experiment of the 3D bioprinter is limited to in vitro human cell culture and organ printing for medical treatment, and no other human or illegal experiments are allowed to be conducted.

After the notification, the patient's guardian must be notified and their consent must be obtained.

In the ward of Hongxin International Hospital, the little girl Zhang Yan is getting weaker and weaker day by day, and even speaking has become difficult.

Frequent treatments have severely overdrawn her bodily functions, and her eyes, which were once agile, have now become hollow, like those old people who are about to die.

In the attending doctor's office, the attending physician is talking to her adoptive father and adoptive mother about an important matter.

"Zhang Yan's situation, if she does not have a bone marrow transplant, it is estimated that it will last for two months at most. The attending doctor tried his best to speak in a calm tone, but Zhang Yan's adoptive mother still couldn't help but moisten her eyes, although they had long expected this outcome, but it was extremely uncomfortable to see the child suffering from illness.

"Doctor, we've been trying hard to find his adoptive parents...... But ......," Zhang Yan's adoptive father sighed helplessly.

"I know that this kind of thing can't be forced. "As doctors, we want our patients to be cured. ”

"Now there's another way, I don't know if you'd like to give it a try. I've told you in advance, it's a very risky solution, and the outcome is unimaginable!

"Whatever the solution—whatever the solution, we're willing to try!" Zhang Yan's adoptive mother said immediately, and now they have nothing to do, as long as there is a glimmer of hope, they want to try.

"That's right. The attending doctor introduced: "Now we at Hongxin Biotechnology Research Institute are researching a new medical technology, 3D bioprinting. In short, it is the use of 3D printing technology to create artificial organs in vitro. ”

"3D printed organs?" Zhang Yan's adoptive parents were a little surprised, can medical technology still be like this?

"I'll explain it in more detail. The attending doctor said, "We used this new technology to print a new bone marrow for Zhang Yan." Because the cell culture was taken from herself, there was no allogeneic rejection. ”

"But, I want to emphasize that this is a completely new technology, and no medical institution in the world has ever tried such an experiment before. The success rate of the experiment cannot be guaranteed by the hospital. ”

"I can only guarantee that we are obligated to treat the whole process, and we don't need to pay a penny from you. However, we cannot guarantee the results of treatment. ”

After the doctor finished speaking, Zhang Yan's adoptive mother said directly: "We agree!"

"Agree so quickly, don't you think about it again?" the doctor asked again.

Zhang Yan's adoptive father said: "We don't agree and there is no other way, if there is a chance for the child to survive, if we don't try, we will blame ourselves for the rest of our lives." ”

"We also want the child to know about this matter and see her choice. ”

"Well, no problem. The attending doctor said.

Zhang Yan's adoptive parents told her about it, but Zhang Yan didn't really understand it. Hong Xiaoxiao patiently explained to her several times before she understood, and she agreed directly.

"Xiaoxiao, if my illness is cured, I will play with you every day!" Zhang Yan said as she tried to squeeze out a smile.

Zhang Yan's guardian signed the agreement, and the medical experiment officially began. Lu Zixin didn't have to worry about most of the experimental process, their research team has rich experience in culturing cells, and the only thing to worry about is whether the final 3D bioprinter can replicate the intact bone marrow and successfully transplant it into Zhang Yan's body.

More than a month later, in the cell culture laboratory, the biomaterial ink composed of various cells was loaded into a 3D bioprinter and began to print according to the composition of the bone marrow.

"It's going to be successful!" the researchers prayed silently.

If this time it succeeds, it will be another leap forward for the medical community. With this technology, the need for transplanted organs or lack of blood can be solved from now on.

The 3D bioprinter is running at a rapid pace, and it "piles" cells according to the rules to form bone marrow.

Biological researchers have been paying attention to the real-time holographic projection, which will magnify the printing site, so that they can clearly see the printing process, and any mistakes can be stopped at any time.

Fortunately, nothing went wrong with the printing process, which was controlled by a quantum computer.

There is no difference between the printed human bone marrow and the real human bone marrow, whether it is internal or external, but it is not known whether it will be successful after transplantation. The researchers could have waited a little longer, but Zhang Yan didn't have time to wait.

Outside, in the operating room, the skinny Zhang Yan was lying on the operating table, waiting for a bone marrow transplant, and the bone marrow that had just been printed was sent to begin the transplant operation.

The chief knife took a deep breath, looked at the time, and said in a low voice: "Let's start!"

In the operating room, the tense and busy operation suddenly began. Outside the operating room, the waiting people are even more nervous. There is a 3D bioprinting research team, Zhang Yan's adoptive parents, Lu Zixin, Hong Xiaoxiao, etc., they are silently blessing Zhang Yan and looking forward to the success of this operation.
