MTL - The Black Technology Chat Group of the Ten Thousand Realms-Chapter 515 3D bioprinting
“Simply, it’s 3D bioprinting.”
After the red, I also sent a simulation map. First, the human organs are scanned from the inside out, and the position of each cell is recorded, and then the cells are cultured separately by cell culture technique.
Organs can be printed out by adding these cells as "bio-ink" to a 3d bio-printer.
This kind of technology is still being done by many scientific research institutions on the present earth, and they have successfully printed out organs such as skin, ears, nose, etc., but there is limited progress in blood, bone marrow or internal organs.
Because these important organs are sophisticated in structure and complex in function, they will go wrong if they are not careful, so there is still no major breakthrough.
Mr. l: "This is good, I just need this!"
Group Tip: "After the red, I sent you an exclusive red envelope."
Lu Zixin received a red envelope, which is a 3D bio-printer and related accessories, including in vitro cell culture, organ scanning and so on.
......
The Red Letter Future City Biotechnology Research Institute, Lu Zixin people set up a team to prepare for 3d bioprint research. The first experimental goal is to print out the bone marrow of the little girl Zhang Wei!
Before the experiment, Red Letter also deliberately reported the experiment. This type of experiment can be done without thinking about it. It also needs to be reviewed by relevant institutions. In particular, experiments involving human organs may encounter scientific and ethical issues, and more careful.
The opinions of the approval have come down. The experiment of 3D bio-printer is limited to the in vitro human cell culture for medical treatment, organ printing, and no other human body or experiments contrary to scientific ethics.
After the declaration, the patient's guardian must also be informed and their consent is obtained.
In the ward of Hongxin International Hospital, the little girl Zhang Hao was weaker every day, and even her speech became difficult.
The frequent treatment is a serious overdraft of her bodily functions. Her once-inspired eyes have now become hollow, and those who will walk in the woods.
In the office of the attending doctor, the attending doctor is talking about an important thing with her adoptive father.
"Zhang Hao this situation, if you do not carry out bone marrow transplantation, it is estimated to last up to two months." The attending doctor said as much as possible in a calm tone, but Zhang Wei's foster mother can not help but keep her eyes wet, although they have already expected this The end, but seeing the child suffering from illness and suffering is extremely uncomfortable.
"Doctor, we have been working hard to find his adoptive father and mother. But..." Zhang Hua’s adoptive father sighed helplessly.
"I know that this kind of thing can't be forced." The attending doctor said, "As a doctor, we are most hoping that patients can heal."
"There is still a way, I don't know if you are willing to give it a try. I said good in advance, this method is very risky, and the ending is unimaginable! Can you understand?"
"Which way, no matter what method, we are willing to give it a try!" Zhang Wei's foster mother immediately said that now they have nothing to do, as long as there is a hint of hope, they want to try.
"This is the case." The attending doctor said: "Now our Red Letter Biotechnology Research Institute is researching a new medical technology, 3d bioprinting. In short, it is the use of 3d printing technology, in vitro artificial organs."
“3d printing organs?” Zhang Wei’s adoptive parents were a little surprised, can medical technology still be like this?
"I will explain it in detail." The attending doctor said, "We use this new technology to print a new bone marrow for Zhang Wei. Because it is a cell culture taken from her own, there will be no allogeneic rejection."
"But! I want to emphasize that this is a brand new technology. Before that, no medical institution in the world tried this kind of experiment. The success rate of the experiment, the hospital can not guarantee you."
"I can only guarantee that we are obligated to treat the whole process, and we don't need you to pay a penny. But the results of the treatment cannot be guaranteed."
When the doctor finished, Zhang Wei’s foster mother said directly: “We agree!”
"So fast to agree? Don't you think about it?" the doctor asked again.
Zhang Wei’s adoptive father said: “We don’t agree that there is no other way. If there is an opportunity for the child to survive, if we don’t try it, we will blame ourselves for the rest of our lives.”
"In this case, we still want to let the children know and see her choice."
"Well, no problem," said the attending doctor.
Zhang Wei’s adoptive parents told her about this, and Zhang Wei did not quite understand it. Red and little patient explained her to her several times, she realized that she agreed directly.
"Small, if my illness is good, I will accompany you every day!" Zhang Wei tried to squeeze out a smile and said.
Zhang Wei’s guardian signed the agreement and the medical experiment officially began. Most of the experimental process, Lu Zixin does not have to worry about, their research team has a wealth of experience in cultivating cells, the only thing to worry about is whether the last 3d bio-printer can copy the intact bone marrow and successfully transplant it into Zhangye's body. .
More than a month later, the cell culture laboratory, a biomaterial ink composed of various cells, was loaded into a 3D bioprinter, and printing was started according to the composition of the bone marrow.
"Must be successful!" the researchers present silently prayed.
If this success, for the medical community, it will be a leap. With this technology, the problem of transplanting organs or lack of blood can be solved from now on.
The 3D bio-printer is running at speed, and it will “stack” the cells one by one to form the bone marrow.
Biological researchers have been paying attention to real-time holographic projections, which will magnify the print scene so that they can clearly see the printing process, and any errors can be stopped at any time.
Fortunately, the printing process controlled by the quantum computer did not make any mistakes.
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 not known whether it will succeed after transplantation. Researchers can wait, but Zhang Wei has no time to wait.
Outside, the operating room, the thin Zhangye was lying on the operating table, waiting for the bone marrow transplant, the bone marrow that had just been printed was sent, and the transplant was started.
The main knife took a deep breath and looked at the time. He whispered: "Begin!"
In the operating room, nervous and busy surgery began. Outside the operating room, the waiting people are more nervous. There are 3D bioprinting research teams, Zhang Wei's adoptive parents, Lu Zixin, Hong Xiaoxiao, etc. They are silently wishing Zhang Hao blessing and expecting this operation to be successful.
