On 8 march, mr. Tang, from guangchang county, jiangxi, completed a blood stem cell collection in nanchang as a donor, as well as a special love relay. In 2016, mr. Tang's son was diagnosed with cystalosis, which can be cured only by stem blood cell transplants, and therefore registered with the chinese bone marrow bank to seek a formulation. In march 2017, after successful formulation, the child was cured by a blood stem cell transplant. Mr. Tang remembers his desire for matchmaking success, and remembers the love, 2016
The stem cells, the magical seed of life. In the vast frontier of life sciences, stem cells have been the “key word” of the nobel prize award three times because of their unique biological characteristics and application potential. In recent years, you have heard “break-through” advances in stem cell research, for example, earlier this year, when the north dae-dang hongqi team made a technological breakthrough in a new generation of stem cell preparation, it became the head of many technological media。
So, what's the magic of stem cells? Where does it come from, how does it work and what new techniques will it bring to the preservation of human health
The "source code" of life
Stem cells, undivided cells. It is unique in that, compared to highly trained, functionally specialized cells (e. G. Skin cells can provide a layer of protection to the body, muscle cells can contract and neurons can transmit messages), stem cells are like a student who has not yet received professional training and, despite being unskilled, have great potential to be transformed into any cell in the body, which is precisely the attraction of stem cells。
The two characteristics of stem cells are similar to those of the sun goku sample. For example, the director-in-chief of nine zhistoric cellular technology co. Ltd., takaji, one of them pulls down a milligram and becomes another monkey. It is self-replicating and regenerative, constantly retrofitting itself from one cell to two and two to four, and so on; the second is “seventy-two modulation”, where stem cells can change their own form and, under certain conditions, divide from primitive to mature cells with specific functions。
From the sources of stem cells, there are mainly embryonic stem cells, adult stem cells and induced polyenergy stem cells。
In particular, embryonic stem cells are special cells produced during embryonic development and are also the most capable stem cells. Adult stem cells are stem cells that remain in various parts of the body after the individual has matured. In comparison to embryonic stem cells, adult stem cells are less divided and fertile and less versatile. Inducing polyenergy stem cells to be detected by japanese scientist shinoyama, he observed that certain cells in the skin or blood could be re-engineered through a specific “reprogramming” process。
Reprogramme for life
Why is stem cells so obsessed with science? The chief medical officer of zawahui biology, jasuke, described three samples of stem cells as having a strong presence in the treatment of diseases: “the first is the immune regulation function, which reduces inflammatory cell and inflammation damage through the distribution of various inhibition factors. The second is the promotion of damage repair functions, which are treated through the rehabilitation of local tissues by genocrine factors. Third is the replacement function, which replaces the reduced or dead cells.”
Taking a skin or a drop of blood, extracting a cell, importing a specific transcribation factor for “reprogramming” to create a multi-energy stem cell and further developing its division becomes a human cell of every kind, such as a cardiac cell, a retina cell, a nervous cell, and so on, which is expected to produce a human organ that is free of defects — not by night, but by the scenery that scientists may see following the path that they have opened up in the mountains。
If the presentation is too complex, you can see the organ as a big tree, seducing a multi-energy stem cell like a seed, which, after “watering” “fertilizing”, can be divided into different cell types of the organ, as if it were growing into leaves, trunks, branches。
It is particularly noteworthy that, as a multi-energy stem cell, inter-filled stem cells have a unique potential and function to divide and are one of the earliest and most rapidly developing stem cell types in clinical applications. “inter-filled stem cells, like auxiliary players in games, play an anti-inflammation, immuno-modification and organizational rehabilitation role and indirectly contribute to the regeneration of damaged tissues, as compared to the induction of multi-energy stem cells as primary attackers in games, directly supplementing cells in damaged tissues by dividing them into specific functional cells.”。
The spring of regenerative medicine
Currently, more than 6,000 clinical trials in stem cells worldwide involve hundreds of diseases, including spinal cord injuries, multiple sclerosis and systemic red weaves. Countries such as the united states and the united kingdom have taken the lead in treating diseases with stem cell transplants and have achieved some efficacy. In my country, clinical studies have also been carried out in a number of hospitals to treat diseases with inter-filled stem cells。
“the safety of stem cell therapy is a primary consideration. In the case of treatment of cancer in stem cells, there is a certain risk that it may lead to cancers, tumours and abating them. This requires a rigorous risk assessment to ensure their safety.” the alpine said that clinical trials were needed in the consideration of the safety of stem cell drugs, the selection of appropriate adaptive conditions and the design of clinical trial programmes for corresponding symptoms. The trial was then carried out in accordance with existing clinical test norms, obtaining reliable and accurate data and obtaining approval from the office of drug control and drug control for listing in accordance with the standards of medicines。
In terms of effectiveness, jai mentioned that the research and development of stem cell drugs should focus not only on corresponding and ageing symptoms, but also on the design of stem cell development, with precision positioning to enhance therapeutic effects, such as those based on multi-energy stem cells, which can be divided into functional cells as functional drugs, corresponding to different diseases。
Moreover, the development of stem cell drugs requires a higher scale of production and cost control, with quality assurance. “for the time being, the international mainstream of production is still hand-produced, with limited yields and higher costs, benefiting fewer patients. Next, industrial breakthroughs are needed to further enhance stem cell drug production.” high rock plumes say。
The industry believes that, as technology continues to develop, stem cells will lead to a medical change that will become the third treatment after medicine and surgery. To wake up the sun goku in our body, perhaps it has a different ability. (reporter zhang comfort)
