Is stem cell transplantation harmful to the body?

Safe. There are no cases of old diseases** in Xikang International.

Theoretically, there is no health effect on the body, but in practice there is ***. This effect is present during surgery and blood drawing. According to foreign studies, about 51,024 hematopoietic stem cell heterologous transplants were completed, of which 27,770 were bone marrow transplants and 23,254 were peripheral blood transplants.

Of these 51,024 donors, 5 donors died, including 1 case of Tangerine Ant who died after bone marrow donation and 4 cases died of peripheral blood donation, with a mortality rate of about 10,000 people. There were 37 cases of serious adverse reactions, with a chance of causing illness in about 10,000 people, of which 12 were after bone marrow transplantation (10,000 people) and 25 were after peripheral blood transplantation (10,000 people). In addition, about 20 donors developed malignant hematologic tumors (10,000 people), including 8 donors after bone marrow transplantation and 12 donors after peripheral blood stem cell donation.

The incidence of malignant hematologic tumors is not higher than that of normal age- and sex-related pathogenesis.

Conclusion: There may be a risk of lethality or serious adverse reactions in the donation of bridge-building blood stem cells, which is small but does exist. The human body is a very complex and wonderful organism, and current science is unclear about many functions and mechanisms.

Hematopoietic stem cells are the most mysterious cells, and the onset of leukemia is the result of various factors interfering with it. The collection of hematopoietic stem cells currently requires human interference, so unless science and technology are developed in the future, the collection will be quiet, and it will not interfere with the hematopoietic function at all, and a very small part will be collected from the body, which will be eliminated.

Hematopoietic stem cell transplantation is to use tissue cells collected by autologous, isolated and cultured in the laboratory, and inject proliferating stem cells back into the human body, and accurately reach the corresponding damaged organs and tissues through the self-targeting function of multifunctional activated cells, so as to achieve the purpose of repairing aging and diseased cells, hailizing and rebuilding normally functioning cells and tissues.

Human hematopoietic stem cells are morphologically similar to small lymphocytes and occupy only about 1% of nuclear cells in the bone marrow. Human hematopoietic stem cells are derived from the mesothelial cells of the embryonic yolk sac and are the most unique somatic cell population in the human body. Like APSC pluripotent cells, they are a class of primitive cells with hail self-replication and multidirectional differentiation potential.

Abstract:Stem cell is a powerful cell, it can be cultivated and differentiated into various tissues and organs, transplanted limbs into the human body, so as to play the role of the most malignant disease, stem cell transplantation surgery is the process of extraction, culture, sub-expansion, separation and purification, transplantation. It should be noted that stem cell transplantation is more extreme** and there are certain risks, mainly the risks of transplant failure, rejection and postoperative infection.

Let's take a look at stem cell transplantation. 1. What does stem cell transplantation mean?

Stem cells are a kind of multipotent cells with the ability to replicate themselves, and because they have not yet fully differentiated, they have the potential function of regenerating various tissues, organs and the human body, and the medical community calls them "universal cells", which can be cultivated into human tissues and organs such as muscles, bones, and nerves. The so-called stem cell transplantation is the transplantation of tissues and organs cultivated with stem cells into the patient's body, so as to ** malignant diseases such as diabetes, Alzheimer's disease, Parkinson's disease, etc. The process of stem cell transplantation** is:

1. Material: Take the umbilical cord (4 5cm) of the full-term fetus under sterile conditions.

2. Extraction: Under sterile conditions, remove the blood, umbilical cord adventitia tissue and vascular tissue in the umbilical cord, and extract the umbilical cord Wharton gum tissue.

3. Culture: 1mm umbilical cord Wharton gel tissue was taken under sterile conditions, and the tissue block was cultured by the rolling wall method and double enzyme digestion method.

4. Passaging and expansion: After the cells are fused and passaged, they will be rinsed and digested and continued to be cultured and expanded in proportion.

5. Isolation and purification: Isolation and purification of stem cells by adherent culture screening method, density gradient centrifugation method, and flow cytometry method.

6. Transplantation: After successful stem cell culture, it will be implanted into the patient by intravenous infusion, lumbar puncture, arterial intervention and other methods.

2. Are stem cell transplants risky?

Stem cell transplantation can lead to many diseases, but some friends are worried that stem cell transplantation will be risky

1. Transplantation failure.

Transplantation failure is one of the most serious early complications of hematopoietic stem cell transplantation, due to the failure of graft implantation and hematopoietic reconstitution, the clinical presentation of patients with severe reduction of whole blood picture, accompanied by bone marrow void or hypoplasia, serious complications of infection and bleeding, and difficult management. With the continuous advancement of transplant technology, the incidence of transplant failure has been reduced to less than 5% or even lower.

2. Rejection.

After all, stem cell transplantation is foreign, not the cells of your own body, and the internal organs of the body may have a certain degree of rejection, just like the organs of the body reject the transplanted stem cells and bacteria and viruses as enemies outside the body, which will lead to the rejection of the reaction of the carryover.

3. Infection. Due to the suppression of immune function, the patient's body immunity after stem cell transplantation is very low, the ability to resist infection is very weak, and infectious lesions may occur in any part of the body, which may come from complications of transplantation operations, activation of potential infectious pathogens, and exposure to new pathogens in the environment.

It depends on whether you have an autologous transplant or an allogeneic transplant. Autologous transplantation must be harmless. If it is matched in the public library, there has been a slight rejection in the world, but it is not harmful to health.

Human beings develop from fertilized eggs, which are formed by the differentiation of cells. Human aging is caused by the death of stem cells as the number of stem cells decreases as they age, and the rate of renewal is slower than the rate of aging. Stem cells themselves are the primary cells of the human body, and they can be injected into the body to replace the aging and dead cells without harm.

Now it is the replacement of cells, and perhaps in a few years it will become the replacement of organs, and the only way to die is a virus. Because the rate of renewal of viruses is much higher than the rate of renewal of cells.

Hope it helps.

Leukemia patients will be transplanted, if the transplant is possible, it is possible to save life, otherwise it is death, do you say it is harmful or beneficial?

There must be harm, because drugs are used to suppress the immune system before and after. Generally, this is a tumor of the blood system. It can only be said that it is the lesser of two evils. You can ask your treating doctor for details.

What's wrong with you to transplant, how to transplant, if it's a blood system disease to clear the marrow, it must be harmful, if it's anti-aging or something, then it's reassuring, only good and no harm.
