Forbes ranks China as the best country for stem cells. China is at the forefront of the world in stem cells, and there have been more than tens of thousands of cases in China, which provides doctors with a lot of clinical information, and also allows doctors to gain more experience in clinical practice, which is not available in other countries.
So what should we know before the injection and before the injection of stem cells?Is there any effect?The father of stem cells has summarized some of the issues that everyone is generally concerned about, so let's take a look at them today.
01What is stem cell reinfusion?
Stem cell reinfusion, also known as "stem cell transplantation", is a part of cell biology, which is obtained from the isolation and purification of various tissues of the human bodyIntravascular injection or intervention is used to transfer stem cells to damaged organs and tissues to promote cell repair, regeneration and regeneration.
At the same time, it can also repair damaged cells or tissues through the regeneration and differentiation of stem cells through the "self-healing function", so as to achieve the functional remodeling of the body.
02How does stem cells work when they are reinfused into the human body?
Activated dormant cells:Dormant cells are cells that have lost their cellular function, while stem cells can directly activate dormant cells and restore them to normal physiological functions.
Replacement of necrotic cells:The homing of stem cells can replenish the replacement necrotic cells in time, so that the body can maintain normal functions and delay aging.
Repair damaged cells:The external environment has a negative effect on cells, and cells will be damaged during metabolism, while stem cells can repair damaged cells and prevent damage.
Stem cells are a type of cell with a variety of differentiation potential, which can improve the body's functions and improve the vitality of the body, thereby achieving a delay in aging.
03 Who are stem cells** suitable for?
Pursue a young and energetic crowd;
Hyperlipidemia, hypertension, hyperglycemia.
Immune system disorders;
Signs of aging are evident;
Sub-health, high work pressure, irregular life;
People with cardiovascular and liver function decline, endocrine dysfunction, bone degeneration and other physical functions.
04 Which groups of people are not suitable for stem cells**
HIV, hepatitis B active, syphilis positive;
Those who are highly allergic or have a history of allergies;
Malignant tumors, undergoing radiation and chemistry**;
In case of sudden illness, do not take it for 2-3 months;
Coagulation disorders;
Psychosis;Pregnant women;
Severe systemic or localized infection. (Note: Before injecting stem cells, a rigorous physical examination is required and identified by a professional).
05 Precautions for the day before hematopoietic stem cell reinfusion
Mainly light and easy to digest food, do not eat spicy and pungent seafood. Avoid strenuous exercise, get enough sleep, and go to bed early at night.
06 Post-transplant treatment
No strenuous exercise within three days after **, no sauna, salt bath, sauna, mineral salt bath for a week, no x-ray for 2 months.
The injection of stem cells is the same as the injection, except that a slight pain is felt during the puncture, but the pain is bearable. At the time of the infusion, patients may experience a brief episode of fever and allergies, but the symptoms are mild and disappear the next day.
07How long does it take for stem cells to work?
How long can you stay?
First of all, everyone's condition is different, some are sub-healthy, some are diseases, and some are diseases, all of which are due to gender, age, region, genetics, single disease, multiple diseases, disease progression, and so on.
Secondly, the method of blood transfusion is also different, such as arterial, intravenous, local injection, and whether there is a difference in transfusion reaction with other methods
In addition, Xi and rest will also affect the survival and vitality of cells. Usually pay attention to develop a good life habits, develop early Xi go to bed early, get up early, and do more exercise. Finally, cell type, cell number, interval period, etc., will also affect the final result. In short, every question we can think about will have an impact on the role and persistence of cells.
In general, the injection response takes between a few minutes and three days, with cells migrating and biologically reacting, followed by a pharmacodynamic response that lasts for a year to several years.
08 How long can stem cells survive in the human body?
Mesenchymal stem cells are bioactive substances secreted by cytokines with immunomodulatory functions. So we feel that they shouldn't survive in the body for long, and it's better to do their job and get rid of them completely!
According to the existing research findings, whether it is local or systemic injection, whether it is autologous or allogeneic stem cells, the body will gradually remove stem cells, and the speed of their removal depends on the body's immune system, input pathway, cell tissue, cell donor age, in vitro culture time and other factors.
09Are there any adverse reactions?
Adverse reactions such as toxicity, genetic effects, local stimulation, and immune reactions of stem cells are all important contents of preclinical animal experiments and clinical trials. Although there is no guarantee that stem cells will not produce any adverse effects, researchers will evaluate the use of stem cells based on their effects and the risk of adverse effects.
Generally speaking, the application of stem cells in non-serious diseases, such as beauty, sports injury repair, etc., will have a high risk When stem cells are used for serious fatal diseases, due to the comparison of risks and benefits, some small adverse reactions are unavoidable, but the patient as a whole benefits.
10What are the common symptoms after stem cell reinfusion?
1. Excited, energetic;
2. Feeling tired and dizzy;
3. No feeling, very stable;
4. After 24 hours of fever, the body temperature is around 38 degrees, and it will return to normal after 3 days (ibuprofen can be prepared);
5. There will be slight muscle pain. Statistically, people are more tired because of the body's repair and activation, which makes people feel tired, which is a natural recovery response, just like a viral and bacterial invasion.
