The Black Technology Chat Group of the Ten Thousand Realms

"Simply put, it's 3D bioprinting."

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

Organs can be printed by adding these cells as "bioinks" to a 3D bioprinter.

There are also many scientific research institutions doing this kind of technology on the earth, and they have successfully printed organs such as skin, ears, nose, etc., but for blood, bone marrow or internal organs, the progress is limited.

Because these vital organs have sophisticated structures and complex functions, they can go wrong if they are not careful, so there has not been a major breakthrough yet.

Mr. L: "This is good, I just need this!"

Group reminder: "The Red Queen sent you an exclusive red envelope."

Lu Zixin received the red envelope, which contained the 3D bioprinter 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. The first experimental goal is to print out 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, and it needs to be reviewed by relevant institutions. Especially, experiments involving human organs may encounter scientific and ethical issues, and you should be more cautious.

The approval opinion has come down. The experiment of 3D bioprinter is limited to in vitro human cell culture and organ printing for medical treatment, and any other experiments on human body or against scientific ethics are not allowed.

After the declaration, it is necessary to inform the guardians of the patients and obtain their consent.

In the ward of the Red Letter International Hospital, the little girl Zhang Yan was getting weaker and weaker day by day, and it became difficult to even speak.

And the frequent treatment has seriously overdrawn her body functions. Her once agile eyes have now become empty, like those old people who are about to die.

In the attending doctor's office, the attending doctor is talking with her adoptive parents about an important matter.

"In Zhang Yan's situation, if you don't have a bone marrow transplant, it is estimated that it will last for two months at most." The attending doctor said in a calm tone as much as possible, but Zhang Yan's adoptive mother still couldn't help but her eyes were wet, although they had expected this for a long time. In the end, it was extremely sad to see the child suffering from illness.

"Doctor, we've tried very hard to find his adoptive father and mother...but..." Zhang Yan's adoptive father sighed helplessly.

"I know that this kind of thing cannot be forced." The attending doctor said, "As doctors, we most hope that patients can recover."

"Now there is another way. I don't know if you are willing to try it. I said in advance that this method is very risky, and the outcome is unimaginable! Can you understand?"

"Any way - no matter what, we are willing to try it!" Zhang Yan's adoptive mother said immediately, and now they have nothing to do, as long as there is a glimmer of hope, they all want to try.

"It's like this." The attending doctor said: "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 in vitro."

"3D printing organs?" Zhang Yan's adoptive parents were a little surprised. Can medical technology still do this?

"I'll explain in more detail." The attending doctor said, "We used this new technology to print a brand-new bone marrow for Zhang Yan. Because the cells were cultured from her own body, there would be no allogeneic rejection."

"But! What I want to emphasize is that this is a brand new technology. Before this, no medical institution in the world has tried such an experiment. The hospital cannot guarantee the success rate of the experiment to you."

"I can only guarantee that we are voluntary treatment throughout the process, and we do not need you to pay a penny. But we cannot guarantee the results of the 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," said the attending doctor.

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

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

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. The only thing to worry about is whether the last 3D bioprinter can reproduce 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 the 3D bioprinter, and the printing was started according to the composition of the bone marrow.

"It must be successful!" The researchers present silently prayed.

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

The 3D bioprinter is running fast, and it "stacks" 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. If there is any error, they can stop at any time.

Fortunately, the printing process controlled by the quantum computer did not go wrong.

Whether it is internal or external, there is no difference between the printed human bone marrow and the real human bone marrow, but it is unknown whether it will be successful after transplantation. The researchers could wait longer, but Zhang Yan had no time to wait.

Outside, in the operating room, thin Zhang Yan was lying on the operating table, waiting for the bone marrow transplant. The bone marrow that had just been printed out was sent, and the transplant operation began.

The chief surgeon took a deep breath, looked at the time, and whispered, "Start!"

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