Chapter 568 Cell Bank
Six o'clock in the morning, twelve o'clock in the afternoon, six o'clock in the afternoon.
The forum chat room is very active during this time.
It was also at this time that Song Zimo uploaded the latest batch of spinal orthopedic case data to the forum for everyone to study and study.
Johannesson created the forum, but the administrator is Song Zimo.
All case data from the first phase of clinical trials have been sorted out and uploaded to the forum.
On Saturday, Yang Ping will give a live lecture at the forum, answer questions online for members on difficult aspects of new technologies, and comprehensively explain the theory and practical operation of new technologies.
Before the paper is published, forum members will be the first foreigners to learn and master this batch of technologies.
Domestic hospitals such as Xiehe University and Nandu Affiliated Hospital can directly participate in the experiment.
Therefore, this forum has actually become a platform for Yang Ping to promote his new technologies internationally.
The notice of the lecture was sent out on the forum, and it immediately aroused a wave of excitement.
Checking in online during this time has become an essential item for forum members.

The subject of growing muscle from stem cells is progressing slowly.
In reality, this is a huge project that will take several generations to complete, and it is destined to not be so smooth.
To observe cells, it is necessary to have an excellent cell bank.
HeLa cells are the best choice, but HeLa cells are too single. Yang Ping also needs pluripotent stem cells, mature cells, and cells from growing and developing individuals.
In the systems laboratory, the object of Yang Ping's observation was HeLa cells.
Observing the changes as they split, Yang Ping recorded the process in detail.
Then Sisi's tumor cells were observed and found that her tumor cells, like HeLa cells, could divide without limit.
This means that Sisi can use its own cell bank to carry out this ambitious project.
Sisi is a minor and a tumor patient. Not only can she obtain tumor cells, but she can also obtain cells from immature organs, which fully meets Yang Ping's cell source requirements.
This may be Sisi's opportunity.
Yang Ping came out of the system laboratory, took out a book from the bookshelf, "The Immortal Hela", and sent it to Sisi's ward. Sisi went to the rehabilitation department for rehabilitation training. Yang Ping wrote a note and handed the book Place it on your bedside table.

Xiao Su hadn't come down yet, so there was nothing to do for the time being, so Yang Ping decided to go on a house tour alone.
Cui Shukai's father stood by the window and played songs. The nurse knocked on the door and told him to stop singing. Others had complained several times.
Lao Cui was complained for singing in the garden downstairs. He was still complained when he went to the rooftop because the singing was too unpleasant, just like breaking a gong.
I'm so happy, I can't help it!
This is what people like. If you don’t let them sing, they won’t sing.
Seeing Yang Ping coming to check the ward, Cui Xubing immediately asked his son to walk around a few times.
When the spinal external fixator is removed, the focus is on the collapse of the osteotomy site. Collapse may occur due to insufficient strength of the new bone. These are all within the scope of consideration. When dismantling the frame, the strength of the new bone needs to be fully evaluated.
Therefore, Cui Shukai has not experienced any collapse for the time being.
"Professor Yang, a few days ago on the Internet, there was an article saying that spinal external fixators are harmful to people. I really want to chop up the person who wrote the article. It's strange! Today, when I browsed the Internet, they were all articles apologizing for misunderstandings about spinal external fixators. And many big names came out to explain that the spinal external fixator is a new technology for scoliosis correction, which is safe and effective. My phone has been getting hot these days because I asked about the surgery," Lao Cui said frankly.
Yang Ping knew that the giant companies had no choice now and had to eat their own shit.
Such a commotion is equivalent to the advertisement of the century for Ruixing and spinal external fixators.
However, the advertising fee is a bit expensive, but fortunately it is sponsored by a giant.
Since yesterday, the phone number at Sanbo Hospital has been inundated with patients asking about scoliosis correction.
"The clinical trial quota has been filled up early, and we have to wait until it is officially launched later."
Yang Ping told Lao Cui.
Lao Ji's sense of superiority is overwhelming. If he is caught with such a good opportunity, if he queues up now, he will have to wait until such a long time.
The process of truly comprehensive clinical application of a product is still long.
Because medical technology is generally promoted cautiously, it must be very mature before it can be promoted on a large scale.
After checking around the wards, Yang Ping thought of Sisi and went to see if Sisi was back. Sisi was in the last ward. She was hospitalized when she needed re-examination. She was not hospitalized at ordinary times and lived in a rented house next to the hospital.
The external fixator on her thigh has also been removed and the femur was successfully lengthened. However, during the surgery to remove the tumor, a large range of muscles were also removed. The entire hip and thigh lost their power devices. All affected limbs had no ability to move and could only Mobility with crutches and wheelchair.
This time it was time for a review, so Sisi was hospitalized for a few days.
Yang Ping knocked on the door, and heard the little girl's voice inside. She was back.
"Sisi, I'm going for a walk with my brother."
Yang Ping pushed the door open and went in.
Sisi was opening the book that Yang Ping gave her. Yang Ping usually gave her books to read.
The little girl smiled like a flower: "Okay."
Yang Ping pushed Sisi in a wheelchair, while her mother was packing the sheets of discharged patients and sending them to the logistics department for washing.
"Mom, my eldest brother and I went out to play." Sisi greeted her mother.
"Don't play too long, it will waste your brother's time."
Seeing her daughter happy makes the mother happy too.
Pushing Sisi out of the lobby door on the first floor, the security guard saluted and greeted Yang Ping.
In the hall, some patients stood by the wall and read the doctor's introduction on the wall.
Some patients sat in the waiting area, waiting to be called.
The buildings of Sanbo Hospital are distributed in an orderly manner and have a sense of hierarchy.
The entire hospital site is relatively wide, especially the greening is very good.
"Is there anything you want to tell me?" The little girl was very smart.
Yang Ping pushed her to walk slowly along the path in the woods. At this time, fragments of the sunset were shining from the leaves, making the world appear very peaceful. "The little head has a good IQ." Yang Ping praised her.
"Did the re-examination find tumor cells again?" Sisi was calm and not worried at all.
Yang Ping shook his head: "I said, you have to learn to coexist with them, but my focus is not on that now."
"Did you see the book I gave you?" Yang Ping asked.
""Eternal Hela"?"
Sisi had already opened a few pages and already understood the general content of the book from the introduction.
"This is exactly what I want to tell you. I plan to capture cells from you, either normal cells or tumor cells, and then culture them in the laboratory so that they can divide independently like HeLa cells."
"Normal human cells have telomeres, a small DNA-protein complex at the end of chromosomes. Every time a cell divides, a section of telomeres will be lost, so after about 50 divisions, the cells can no longer divide. This is Heifer LIKE CAP ”
"But your tumor cells are different. They are very special. I have seen that your tumor cells are just like HeLa cells. There is a kind of telomerase that can re-add the telomeres lost by division indefinitely. This leads to Since they have no limit to division and can proliferate endlessly, they are similar to immortal cells, which is exactly what I want.”
"If I'm not wrong, as long as these cells have sufficient nutrients, they can grow crazily. Their number can double in 24 hours. They are not limited by the number of divisions or equipment. When ordinary cell culture is When they can only be covered with a thin layer on the test tube wall, these cells can accumulate wildly in the culture medium. Using these cells, I can study many things, including treatments for you.”
"I want to use you as a cell bank, but extracting cells sometimes hurts. Sometimes I have to extract bone marrow to find stem cells. Sometimes I have to puncture the tumor to extract tumor cells. Sometimes I need to extract your normal tissue cells. Are you afraid? ”
Yang Ping thought it would be better to talk to the child in advance, and then talk to her parents.
If you want to save her, this is the only way. Maybe you can crack the code of the tumor cells in her body, just maybe.
"I'm not afraid!"
Sisi turned her head and looked at Yang Ping firmly:
"Does this mean I can participate in your experiment?"
"Of course! You are my experimental partner."
Yang Ping took the hand she extended and held it.
"That's great. Even if Hela dies, her cells will still be alive and have saved tens of millions of people. Then if I leave this world, these cells will always be in your laboratory for you to study, and they can also save many people. ”
There was an innocent smile on Sisi's face, without a trace of fear.
"No, you won't die. Believe me, I can race it."
Yang Ping held her little hand.
