Silicon Valley

China has always attached great importance to face-saving projects, and the buildings built for foreigners are often called artifacts, able to stand upright in an earthquake. Therefore, Henry handed over the construction of the hospital building to a Chinese construction company.

For Henry, the immediate priority is to speed up the recruitment and training of medical personnel.

Most of the hospitals in China are foreigners with fair skin and blond hair, which is too outrageous. Today's China is already very developed. There are actually many excellent nurses and doctors, but there is a shortage of top doctors. However, the desire to train top doctors is often related to the high-tech equipment of local hospitals. As the saying goes, if a worker wants to do a good job, he must first sharpen his tools. Without good equipment, how to conduct medical research? Henry can create this condition.

Chinese people have been very smart since ancient times. Henry can use the hospital to train more talents for himself, and then send them to the Gene Umbrella Company.

As there are more and more research projects on Gene Umbrella, it is more urgent to find more talents. An illiterate can only look at the sky from the bottom of a well, because in his eyes, the world is only so big; but the gene umbrella is like a well-educated scientist. As he explores more mysteries of the universe, he feels more and more that he is only touching To the tip of the mysterious iceberg of the universe, not even the tip of the iceberg!

There is an animal on the earth called "Lighthouse Jellyfish", which will return to the polyp state after sexual maturity, and can repeat this process infinitely, thus possessing the ability to rejuvenate, that is, immortality! At present, Gene Umbrella Company has a dedicated team to study it, hoping to crack the secret of its immortality, and then apply it to human beings!

According to the research of scientists, the secret of the immortality of lighthouse jellyfish is completed in the process of cell transdifferentiation. During this process, all cell types and functions of the lighthouse jellyfish are changed, and this functional transformation is accompanied by organ regeneration. Perhaps it is this process of cell change that creates the immortal body of the "lighthouse jellyfish"!

Although I have roughly understood the secret of immortality of the "lighthouse jellyfish", why do all its cells undergo reverse differentiation? This is really hard to understand. It is well known that ordinary cells do not have the ability to replicate and differentiate. Only "stem cells" have the ability to replicate and differentiate. But how does the lighthouse jellyfish do it? Perhaps a certain gene of the lighthouse jellyfish played a key role, allowing the lighthouse jellyfish to have such magical abilities! As for the gene, it is still under study!

Here, I can't help but boldly put forward a hypothesis, what if humans also have this gene? Then, is it possible to rejuvenate and live forever like the "lighthouse jellyfish"? !

Everything is full of doubts!

Although Gene Umbrella has encountered difficulties in the research of "Lighthouse Jellyfish", it has made great achievements in the research of "stem cells"!

Here, I have to ask again, what are stem cells?

Stem cells, also known as origin cells, are not fully differentiated and immature cells, which have the potential to regenerate various tissues, organs and the human body. They are called "universal cells" in the medical field! ! ! Stem cells can be further classified according to their developmental potential: totipotent stem cells, pluripotent stem cells and unipotent stem cells. Among them, totipotent stem cells, also known as "embryonic stem cells", can be transformed into any cell in the human body, in other words, they can directly clone a complete person!

Every human body has stem cells, but totipotent stem cells or "embryonic stem cells" can only exist when embryos are formed, and embryos are small lives that survive in the mother's uterus. The international community is full of doubts about the research on "embryonic stem cells". To call it unethical is to kill life!

Stem cells can proliferate and differentiate to form other cells. Therefore, scientists can induce them to differentiate into various possible cells and repair damaged organs to solve many medical problems. However, in the view of Gene Umbrella, this technology is at the entry level. Most countries in the world already have this capability, and even cloned many animals.

And what is Gene Umbrella going to research?

Cell reversal technology! ! !

Although Gene Umbrella did not know how the lighthouse jellyfish transformed all ordinary cells into stem cells, it undoubtedly pointed out the direction of research for Gene Umbrella, that is, ordinary cells can be reversed into stem cells! ! !

The root of human aging is essentially the aging and reduction of cells, and the aging and reduction of cells is caused by the aging of stem cells. Stem cells cannot proliferate and differentiate after aging, so ordinary cells cannot be renewed normally, just like rare animals becoming extinct, eventually causing human aging. Through this technology, Gene Umbrella can transform ordinary cells in the human body into new stem cells, and then proliferate and differentiate, so that the tissues and organs of the human body can remain youthful forever!

As far as Henry knows, the Japanese "almost" touched the tip of the iceberg in 2006. They used retroviral vectors to transfer four genes into adult cells and reprogrammed adult fibroblasts in mice. As a result, these ordinary adult fibroblasts showed characteristics similar to embryonic stem cells and could realize the functions of proliferation and differentiation. Once the results of this research were released, it immediately caused a huge sensation in the scientific and technological circles, and was subsequently selected as the "Top Ten Scientific Breakthroughs of the Year" by the American "Science" magazine! At first, some people were skeptical about the research and found it unbelievable. However, when researchers in other countries adopted the same method and obtained the same results, the controversy immediately subsided.

Under Henry's guidance, the study had been completed before 2000, but it was not made public. At that time, the researchers of Gene Umbrella saw that ordinary cells could really turn into stem cells, and they were very excited, and their morale was boosted for a while, thus speeding up the research on "cell reversal technology"!

Just this evening, when the sun was setting, Gene Umbrella suddenly called Henry.

"Mr. Williams, we have successfully used the 'cell reversal technology' to synthesize human skin into skin stem cells!!!"

The voice on the other side of the phone was very excited. This is the first time Gene Umbrella has transformed ordinary human cells into stem cells in more than two years!

Henry was still very calm, and said unhurriedly: "Very good, keep working hard! However, you must also know that we have only reversed a type of human stem cells, and there is still a long way to go in the future!" Although human stem cells Very few, but their number and types have not been clearly determined so far, and there is a long way to go!

"Yes! We understand!"

"kindness……"

Henry nodded, and suddenly thought that stem cells became popular in the beauty industry, becoming an anti-aging artifact, and the favorite of the rich!

A professor at the Chinese University of Hong Kong cited an interesting data about stem cells: a skin stem cell can be differentiated into 100 generations to produce a total of 15 billion skin cells, which is enough to cover the whole body skin of 10 adults. This is enough to prove how important stem cells are to skin regeneration and repair.

Henry couldn't help but have a flash of inspiration. He opened a beauty salon and treated with stem cells. He will definitely make a lot of money!
