? What is a stem cell?A
Stem cells are primitive and undifferentiated cells that have the ability to regenerate and differentiate, and can proliferate into cells that are identical to each other and can differentiate into other functions. Because of these characteristics, stem cells can be used to repair damaged tissues or organs, and even construct complete organs.
? Why store stem cells?AIn addition to the function of self-renewal, proliferation and differentiation into stem cells, mesenchymal stem cells can also be driven to repair damaged tissue. Mesenchymal stem cells can be obtained from different tissue sources such as bone marrow, umbilical cord, placenta, and fat, and can be differentiated into osteoblasts, chondrocytes, tendons, cardiomyocytes, neurons, and fat cells, etc., in cell therapy, tissue engineering, and regenerative medicine. The application has considerable potential. When you are healthy, storing the mesenchymal stem cells from the body, and promoting your own health in the future, you can say that you are preparing an insurance.
? Is the storage environment safe?AThe stem cells of our customers are stored in the company's GTP laboratory. The building is strong and reliable, and the fireproof and waterproof are up to the highest standards. The "Good Tissue Practice (GTP) Laboratory" established by the company has passed the inspection by the Department of Health.
At the same time, the company uses high-quality shipping and storage equipment to better ensure that your stem cells have the safest storage environment. For details, please refer to the stem cell storage equipment of this product page.
The company also has its most powerful technical support, you can trust the stem cells to the Aobit biotechnology.
? Cancer and cancerACells in the human body will form tumors due to abnormal division.
There are two kinds of tumors, one is a benign tumor, and the other is a malignant tumor or cancer.
Because human cells are abnormally divided, out of control, and aggressive, they will destroy neighboring tissues or organs, and will also enter the blood circulation to cause other organs or tissues to produce new tumors (the cancer cells spread and metastasize), so the cancer name is the site where the cancer occurs. Named, such as breast cancer or colorectal cancer.
Quxi cancer is most afraid of the spread and metastasis of cancer cells, but the spread of cancer cells, there is still a chance to cure, and should not lose hope.
Anti-cancer and anti-cancer, you need to keep in mind the concept of "early detection, early treatment".
? What is immune cells?AImmune cells are patrol guards in the body. They swim in the body and can detect invaders, bacteria, pathogens, and destroy them. They can also eliminate aging cells and metabolic waste.
The immune system is divided into two categories, innate immunity and acquired immunity.
1. Innate immunity: no need to contact pathogens, microorganisms, etc. to activate immune cells, but with inherent resistance, such as physiological barriers (skin. mucosa)
(1) Cells belonging to innate immunity include natural killer cells (NK cells), dendritic cells (DC cells), macrophages...
(2) Natural killer cells: lack of specific antigen receptors on the cell surface, responsible for non-specific defenses, killing tumor cells and cells infected with viruses
(3) Dendritic cells: They have the ability to phagocytose and present antigens. After presenting antigens on the cell surface, they awaken T cells for immune response.
(4) Macrophages: phagocytosis of dead cells, cell debris, and pathogens
2. Acquired immunity: the ability of an individual to actively invade an invader. The immunity obtained after the vaccine is administered, etc.
T cells, B cells, and CIK cells belong to acquired immune cells.
(1) T cells: can be subdivided into poisonous T cells. Helper T cells. Regulatory T cells. Memory T cells
Toxic T cells are like a killer, identify antigens in major histocompatibility complex type 1 (MHC I) through their surface antigen receptor (TCR), and can identify foreign pathogens or cancer cells and kill them.
There are also antigen receptors on the surface of helper T cells, mainly identifying type II (MHC II) antigens of major histocompatibility complexes.
Memory T cells: remember each time the invading antigen, when the same antigen re-invades, it will immediately produce an immune response and the reaction will increase
(2) B cells: divided into plasma cells and memory B cells
Plasma cells can produce antibodies. When antibodies and antigens are combined, the antigen cannot bind to healthy cells or the antigen-bearing pathogens are destroyed. Loss of activity and the like is more likely to be phagocytized by phagocytic cells.
(3) CIK cells: immune cells induced by cytokines, which have the anti-tumor advantage that NK cells are not restricted by MHC antigens, and have strong and potent killing properties of T cells.
