Stem cell implantation

　　What Is Stem Cell?

　　In the process of cell differentiation, cells will completely lose the ability to split due to high differentiation, eventually they will die. Therefore, in the process of development, in order to make up for this deficiency, human body remains a part of undifferentiated primitive cells, which are called stem cells. Stem cells are kind of primitive cells (also the original cells of our body) which can self-renew and have the potential of multi-directional differentiation. Under certain conditions, they can be specially induced to directionally differentiate into a variety of functional cells or tissues and organs, the medical community calls them as" universal cells".

　　Many human diseases are related to the death of cells. After stem cells are implanted into human body, they can repair or replace the damaged lesions and aging cells, so as to achieve the purpose of treatment.

　　Currently, domestic and international techniques for preservation and transplantation of stem cell have been applied in clinic and it shows good effects in diseases like neurological diseases and autoimmune diseases.

　　Types of Stem Cell

　　According to the potential of differentiation, stem cells basically can be divided into the following three types.

　　(1) All-function stem cell

　　Those stem cells have potential to differentiate complete individuals, such as embryonic stem cells, which have the morphological characteristics cells similar to early embryonic cells and have very strong ability of differentiation, can unlimitedly proliferate and differentiate into more than two hundred kinds of cells from whole body and further form all tissues and organs of the body.

　　(2) Multifunctional Stem Cells

　　Those stem cells have potential to differentiate into a variety of tissues instead of the ability to grow into complete individuals, which indicates that their potential of development is limited. Typical example is multifunctional hematopoietic stem cell of bone marrow. It can differentiate into at least 12 types of blood cells instead of other cells apart from hematopoietic system.

　　(3) Monofunctional stem cells (Specific or partial stem cells)

　　These kinds of stem cells can only differentiate directionally into one type or two types of cells that are closely related, such as stem cells in the basal layer of epithelium, myoblasts contained in muscle which is also called satellite cells.

　　The Source of Stem Cells

　　Currently, stem cells mainly are extracted from bone marrow and cord blood. Stem cells in bone marrow are more primitive than those from peripheral blood, while stem cells in cord blood are more primitive than those from bone marrow. Therefore, stem cells in cord blood has the strongest ability to self renew, the fastest time to reproduce, while those in bone marrow take the second place. Besides, stem cells in cord blood account for the largest percentage than those in bone marrow.

　　Principle of Stem Cell Transplantation

　　The principle is through isolation, culture, induced differentiation.ect in vitro, stem cells can be cultivated to be a kind of new, normal, and younger cells, tissues, organs. Through specially transplanting into the body, they can instead the cells with normal or unusual death. It has brought an epoch-making revolution for the treatment of a variety of intractable diseases.

　　Advantages of Stem Cell Transplantation

　　Stem cell transplantation means that transfuse stem cells as” medication” into patient’s body and they will repair the damaged tissue cells and organs in order to control diseases. This therapy does not replace structure and function of the original tissues and organs, but it can realize the unexpected effects that other treatment cannot reach.

　　1. It will not cause immunological rejection

　　2. It does not need to know the exact mechanism of the disease

　　3. Source of stem cells are extensive and it is convenient to get

　　4. There is no side effects like conventional treatment may cause and its effects are confirmed.

　　Clinical application

　　The conventional treatment methods widely used all over the world are hard to treat the difficult and complicated diseases such as Type 1and type 2 diabetes, diabetic foot, hepatocirrhosis, severe liver diseases, nephrotic syndrome, lupus nephritis, necrosis of femoral head, myasthenia gravis, male sexual dysfunction and peripheral vascular diseases.ect. Clinical treatment of stem cell transplantation can be applied to those patients with the disease mentioned above.

　　Quality of stem cells is very important for transplantation so the method that simply separate patient’s stem cells from peripheral blood or bone marrow and transfuse into the patient’s body basically has no good effect.

　　Modern Cancer Hospital Guangzhou builds a single biology laboratory in which we adopts special techniques to perform isolation and purification in vivo so as to guarantee purity of those stem cells. Before collection, those stem cells will be strictly screened. From collection, subculture and transfusion to patient’s body, every step strictly follows the criterion of quality control, so as to guarantee the safety of this treatment.

　　“One station” medical system constructed by Modern Cancer Hospital Guangzhou combining multiple disciplines, can perform comprehensive diagnosis and treatment for patients under the condition of without adding patients’ burden. Therefore, on one hand, it can provide all-round and heartfelt medical services, and on the other hand, it improves medical efficiency and level. There are many channels can be applied to conduct the communication between patients and doctors, like online consultation, email, telephone conversation, and face-to-face consultation. All these consultation services can effectively help patients to fight the cancer. While the medical team faced by the patients includes doctors, nurses, dietitians, interpreters and so on to meet various demands in different level of different countries. Patients would be more confident under the unobstructed communication environment to cooperate the hospital to diagnose and treat the diseases.
