Chapter 496

China has always attached great importance to face project, and the buildings built for foreigners are usually called artifact, which can stand up in the earthquake. So Henry gave the construction of the hospital building to the Chinese construction company.

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

Most of the hospitals in China are foreigners with white skin and golden hair. That's too outrageous. Today's China is very developed. There are many excellent nurses and doctors, but there is a lack of top doctors. However, the cultivation of 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. How to conduct medical research without good equipment? Henry can create that.

Chinese people have been very smart since ancient times. Henry was able to use the hospital to train more talents for himself, and then send them to gene umbrella company.

With the increasing number of gene umbrella research projects, it is more and more urgent to find more talents. An illiterate can only look at the sky from the bottom of the well, because in his eyes, the world is only so big; The gene umbrella is like a scientist who has learned a lot. As he explores the mysteries of the universe, he feels more and more that he has only touched the tip of the iceberg, or even less than the tip of the iceberg!

There is an animal on the earth called "lighthouse jellyfish". After sexual maturity, it will return to the Hydra type state, and can repeat this process infinitely, so it has the ability to rejuvenate, that is, immortality! At present, gene umbrella company has a special team to study it, hoping to crack the secret of its immortality, and then apply it to human beings!

Scientists infer that the secret of Lighthouse jellyfish's immortality is in the process of cell transdifferentiation. In this process, all the cell types and functions of Lighthouse jellyfish will change, and with this functional transformation, organ regeneration will occur. Perhaps it is this process of cell change that makes the lighthouse jellyfish immortal!

Although we have a general understanding of the secret of Lighthouse jellyfish's immortality, why do all its cells undergo reverse differentiation? It's really hard to understand. As we all know, ordinary cells have no ability to replicate and differentiate. Only stem cells have the ability to replicate and differentiate. But how does the lighthouse jellyfish do it? Maybe some gene of Lighthouse jellyfish plays a key role, which makes lighthouse jellyfish have such magical ability! As for what gene it is, it is still under study!

Here, I can't help but boldly put forward a hypothesis, if humans also have this gene? So, can it be as "lighthouse jellyfish" to rejuvenate and live forever?!

Everything is full of questions!

Although gene umbrella has encountered difficulties in the research of "lighthouse jellyfish", it has made great achievements in the research of "stem cells"!

Here, again, what are stem cells?

Stem cells, also known as the origin of cells, is a kind of underdifferentiated and immature cells, which has the potential function of regenerating various tissues and organs and human body. Medical circles call it "universal cells"!!! According to the developmental potential, stem cells can be divided into totipotent stem cells, pluripotent stem cells and monocyte stem cells. Among them, totipotent stem cells, also known as "embryonic stem cells", can be transformed into any human cell, in other words, can directly clone a complete human!

Every human body has stem cells, but totipotent stem cells or "embryonic stem cells" can only exist when the embryo is formed, and the embryo is a small life that lives in the womb of the mother. The international community is full of doubts about the research of "embryonic stem cells", saying that it is against ethics and killing 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 company, this technology is at the entry level. Most countries in the world already have this ability, and even have cloned many animals.

And what does gene umbrella company want to study?

Cell reversal technology!!!

Although gene umbrella doesn't know how lighthouse jellyfish can transform all ordinary cells into stem cells, it undoubtedly points out the research direction of 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, which is caused by the aging of stem cells. Stem cells can't proliferate and differentiate after aging, so ordinary cells can't get normal renewal, just like the extinction of rare animals, which eventually leads to human aging. Through this technology, gene umbrella can make ordinary cells in human body "transform" into new stem cells, and then through proliferation and differentiation, keep human tissues and organs young forever!

According to Henry, the Japanese "almost" touched the tip of the iceberg in 2006. They used retroviral vectors to transfer four genes into adult cells and recompile adult fibroblasts of mice. As a result, these ordinary adult fibroblasts show the characteristics similar to embryonic stem cells and can realize the function of proliferation and differentiation. As soon as the research results were released, it immediately caused a huge sensation in the scientific and technological circles, and was later selected as the "top ten scientific breakthroughs of the year" by the American journal Science! At first, some people doubted the research and thought it unbelievable. However, when researchers from other countries took the same approach and got the same results, the controversy subsided immediately.

Under Henry's guidance, this study was completed as early as 2000, but it was not published. At that time, the researchers of gene umbrella saw that ordinary cells could really turn into stem cells. For example, they were very excited after beating chicken blood. For a time, their morale was greatly boosted, thus speeding up the research of "cell reversal technology"!

Just this evening, as the sun was setting, gene umbrella suddenly called Henry.

"Mr. Williams, we have successfully synthesized skin stem cells from human skin by using 'cell reversal technology'!"

The voice across the phone is very excited. This is the first time in more than two years that gene umbrella has transformed human ordinary cells into stem cells!

Henry was calm and said, "very good, keep up! However, you should also know that we have only reversed a kind of human stem cell, and there is still a long way to go in the future! " Although the number of human stem cells is very small, there is no clear number of their number and types so far. There is a long way to go!

"Yes! We understand

"Well..."

Henry nodded, and suddenly thought that stem cells became popular in the beauty industry, becoming an antiaging device and the favorite of the rich.

A professor from the Chinese University of Hong Kong cited an interesting data about stem cells: a skin stem cell can differentiate into 100 generations and 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 for skin regeneration and repair.

Henry can't help but have a flash of inspiration. He can definitely make a lot of money by opening a beauty salon and treating with stem cells!
