First of all, you should know that there are many kinds of stem cells on the market, but they are all playing with concepts.
Stem cells do exist and are effective, unlike some media and even "experts" who say that stem cells are pure scams. It is irresponsible to say so. Just look at the international reports on stem cells. Secondly, the current domestic stem cell market is indeed chaotic. Various methods of extracting stem cells, the process of replication, and a dazzling array of fancy terms seem to be the trend as long as they are linked to stem cells. And all kinds of so-called not bad money, as long as it can make people rejuvenate, are ready to move. No way, stem cells are just a general term. The so-called carcinogenicity of stem cells is not false, because embryonic stem cells are not allowed in clinic at present, which is also the reason, but mesenchymal stem cells are not. Mesenchymal stem cells have been allowed to be used in clinic in some countries and have a good response.
Thirdly, I often hear friends tell me that plant stem cell has been introduced recently. Well, how can I put it? Anyone with poor biology knows that the cell structure of plants and animals is different. How can plants say stem cells? It is true that animal stem cells repair damaged skin. In some animal experiments, scientists have found that animal stem cells can differentiate into skin cells, which can help skin wounds recover. However, this stem cell is different from other stem cells, and there is a huge difference between plant cells and animal cells. Plant stem cell can only differentiate into other types of plant cells, and it is absolutely impossible to differentiate into human cells. Therefore, it is unrealistic to expect plant stem cell to provide new skin cells to repair damaged skin. Of course, even if it is realized, I'm afraid no one wants to grow "plant-like" skin with cell walls and chloroplasts on their faces or arms.
Fourth, usually the laboratory or R&D team will do experiments with animals first, and then it can be used in human body after countless times. Is it really that good as far as the once popular rejuvenation technique of sheep placenta is concerned? In fact, the best thing is nothing more than hormones and animal hormones, that is, hormones. Injecting exogenous hormones will inhibit their normal secretion of hormones. When people get older, hormone secretion will indeed gradually decrease. What are the side effects after using stimulants? Think for yourself! Unless you are really rich, you can play like this again and again. Once you stop using it, you will know that it is terrible to go to Switzerland and Germany to shoot sheep placenta.
Finally, let's go back to stem cells. Now people are talking about stem cells. After reading the above, you can probably understand that the "stem cells" that many people understand now may not be the same thing at all. There are many kinds of stem cells, so I won't explain them one by one. The stem cells that most people talk about now are nothing more than embryonic stem cells, hematopoietic stem cells and mesenchymal stem cells.
A. Embryonic stem cells have the best differentiation ability, but there are some problems in acquisition and replication, so they are not used in clinic. They are only used for research in some permitted countries. Most people say that stem cells are carcinogenic and ethical, but they only exist in embryonic stem cells.
B. Hematopoietic stem cells, as you can know from their names, are most closely related to blood. Is it closely related to improving skin and internal organs to extract stem cells from blood and then replicate them and inject them back?
C. Mesenchymal stem cells do have the function of repairing various parts and organs of the human body, and they are widely available. Mesenchymal stem cells can be found in umbilical cord blood, bone marrow, fat and other parts, and there is no need for strict matching in application. Therefore, they are also the most potential stem cells. At present, the leading countries in the world are all countries that are open to stem cell research, such as the United States, Ukrainian, Japanese, China and Taiwan Province Province of China, and most of them are stem cells.
Japan and Taiwan Province Province are mature areas where mesenchymal stem cells are really used for cosmetic surgery, while South Korea, a "plastic country", simply does not have the ability to replicate stem cells. Dr Guo's research and development team in Taiwan Province Province has successfully replicated mesenchymal stem cells to the N power. Even so, there are still some markets in Taiwan Province Province that mislead stem cells to rejuvenate. For example, we all know that the so-called autologous stem cells are used for repair. Excuse me, if you have a problem or decline in a certain part or organ, it is because your own stem cells cannot be repaired. Can you pull out your stem cells with reduced repair function and return them for repair? I don't think so.
Therefore, truly effective stem cells must be extracted from healthy people after strict screening. Because there is no strict pairing of mesenchymal stem cells, you should have a general understanding of what is the rejuvenation of autologous stem cells. Stem cells extracted from blood are not mesenchymal stem cells at all. As for the injected "stem cell liquid", it is nothing more than adding some amino acids and harmless nutrient solution.
These are my views on the dazzling array of "stem cells" on the market at present, hoping to help you to some extent.
