1. What is a stem cell?
Our body consists of about 60 trillion and more than 200 kinds of cells, but these cells are just a small fertilized egg at first. After numerous divisions, countless cells were formed, and then these cells differentiated into cells with different shapes and functions, some into muscle cells, and some into nerve cells. Every cell in our body (please refer to the picture below) has a short life, just like our skin and blood. Some cells are constantly dividing into new cells to maintain the replaced tissues, and some cells are used to repair cells damaged by our diseases and injuries, which is the cells with this powerful ability. It is with "stem cells" that we can maintain our bodies from fertilized eggs to adulthood.
"Stem cell therapy" is to extract stem cells from patients' own adipocytes and then transplant them into patients through special transplantation techniques to repair cells and tissues that have lost their normal functions, regenerate them and improve symptoms.
Characteristics of stem cells:
Stem cells have two abilities: [differentiation ability] and [self-replication ability]
[Differentiation ability] refers to various cells that can differentiate into skin, blood and other parts of the body.
[Self-replication ability] refers to the ability to divide into cells with the same ability as itself, which means that stem cells have the ability to divide into stem cells.
Types of stem cells and their differentiation potential
Relationship between stem cell number and age
With the increase of human age, there are fewer and fewer stem cells in the human body.
? Second, stem cells treat patients' diseases.
At present, the most commonly used types of diseases are diabetes, cardiovascular and cerebrovascular diseases and neuronal damage diseases.
1. Diabetes
Diabetes is still an incurable disease. Patients need insulin for life to lower their blood sugar. Diabetes itself is not terrible. What is terrible is the complication of diabetes. Diabetes mellitus has many complications, as high as 100, which is the most complicated disease known at present. Many patients died of complications of diabetes. More than half of the deaths are caused by cardiovascular and cerebrovascular diseases, and 10% is caused by nephropathy.
The blue line in the picture shows the blood sugar level of the patient after insulin injection, which is high and low and unstable. After stem cell therapy, the blood sugar level will rise at first, and after the rising stage, the blood sugar level will drop until the blood sugar standard range is 70- 109 (this range is used in Japan, which is different from that in China), and then the blood sugar level of the patient has been within the standard range for two years, which is very stable.
2. Cardiovascular and cerebrovascular diseases
Cardiovascular and cerebrovascular diseases are common diseases that seriously threaten human health, especially middle-aged and elderly people over 50 years old. They have the characteristics of high morbidity, high disability and high mortality. Even with the most advanced and perfect treatment methods, more than 50% of the survivors of cerebrovascular accidents still can't take care of themselves completely. The number of people who die of cardiovascular and cerebrovascular diseases in the world is as high as150 thousand every year, ranking first among all causes of death.
Take cerebral infarction as an example, once the blood in the brain does not circulate, it will lead to irreversible brain necrosis. The necrotic part will affect people's motor center, language center and so on. Therefore, if the blockage is not very serious, it will lead to bad movements, slow response and memory loss. Serious will lead to hemiplegia, paralysis and so on.
Stem cells can regenerate blood vessels, rebuild blood circulation, improve blood flow and repair and regenerate nerve cells. The released cytokines can protect brain necrotic tissue from edema deterioration and prolong the treatment time of patients, thus greatly improving the curative effect of stroke patients.
Generally speaking, stem cell therapy can rebuild the necrotic tissue of human brain, open up new blood channels, provide nutrition for the brain, make people's nervous system work again and greatly improve people's quality of life.
Experiments show that acute cerebral infarction is eliminated after 2 weeks of stem cell therapy in mice.
3. Neuron damage
Stem cell therapy can also treat neuron injury diseases, such as poliomyelitis, ALS amyotrophic lateral sclerosis (gradually frozen people, such as Hawking) and skin injury (burn, scald, dermatitis recovery). In addition to the above three diseases, stem cell therapy can also resist aging, including:
Stem cell wrinkle removal
Stem cell therapy for dermatitis
Third, the process of stem cell therapy.
Stem cells mainly exist in human bone marrow and fat. Because bone marrow extraction is too painful and difficult, scientists choose to extract it from human fat, which not only relieves the pain, but also reduces the difficulty.
Treatment process:
Do local anesthesia; Doctors extract fat from the human body; Culture in the laboratory; (the most important step) to return to the human body by injection; Late consultation and follow-up.
Stem cells have homing, and the stem cells reinjected into human body will automatically, target and quickly repair the damaged parts of human body, thus achieving the goal of rapid cure.
The picture shows that if there is a problem with human nerves, stem cells will automatically repair neurons; If there are problems with muscles and ligaments, stem cells will automatically repair human tissues; Moreover, organs, red blood cells and osteochondrosis all have problems, and stem cells can automatically repair these problems. It can be seen that the powerful regeneration and repair ability of stem cells will surely bring revolutionary changes to the treatment of human-related diseases.
