Scientists around the world call the 21st century the age of biomedicine. This is understandable because this area of medicine is developing at an incredible speed. In recent years, scientists have received 7 Nobel Prizes for their discoveries in the field of cellular technology! This is far from the limit because the prospects for stem cell treatment today look absolutely limitless!
Stem cells were discovered by Russian-American scientist Alexander Maximov back in 1909. It was he who became the founder of regenerative medicine. The first transplantation of such cells was carried out much later, in the 70s of the last century. While scientists are still arguing about the safety of using stem cells, by the beginning of the 21st century 1,200 cord stem cell transplants were performed in the world.
Stem cells are immature (undifferentiated) cells present in all multicellular organisms. A feature of such cells is their unique ability to divide, forming new stem cells and differentiate, turn into cells of certain organs and tissues. Stem cells are a kind of reserve of our body, due to which the process of cell renewal is carried out.
The use of stem cells in the treatment of diseases is a real breakthrough in modern medicine. There is reliable evidence that stem cell therapy can treat cancer, atherosclerosis, stroke, myocardial infarction, autoimmune and allergic diseases, diabetes and endocrine disorders, spinal cord, and brain injuries. Stem cells improve the condition of the skin, bones, cartilage, and strengthen the immune system.
Stem cells allow you to once and for all get rid of a serious illness, which is much cheaper than trying to treat the disease with medications for the rest of your life. This fact has long been confirmed by patients who use this method to get rid of rheumatoid arthritis and bronchial asthma.
With the help of these biological substances, even infertility can be successfully treated today. Specialists create cells that temporarily suppress the immune function of a woman and as a result of which the body does not reject the fetus. According to statistics, every second woman who decided on this method of fighting infertility became pregnant and gave birth to a beautiful baby.
Embryonic cells are the least differentiated of all stem cells. They can be isolated from the inner mass of the blastocyst (early stage of embryo development) 5-6 days after the artificial fertilization of the egg. This gives them an unlimited potential for growth and differentiation.
Postnatal cells are those obtained from various tissues of postnatal origin (after childbirth) or from an adult person, which has less potential since they have already exhausted part of the potential inherent in them. However, it is postnatal stem cells that represent the most appropriate material for cell therapy at the present stage of its development.
Cord blood cells are the youngest and least differentiated of all cells of postnatal origin. Umbilical cord blood contains mainly hematopoietic stem cells but there are other unique varieties that can under certain conditions ripen into the cells of muscles, blood vessels, liver, heart, nervous, and endocrine systems.
Stemm cell therapy is not a panacea for all ailments. Treatment with such cells has a number of contraindications and can not be used without a balanced approach. What is the essence of this method? It turns out that miracle cells have two important functions.
They divide themselves and activate the reproduction of other cells in the body. This means that during treatment, when the cells enter a diseased organ, they boost the immune system and secrete bioactive substances that activate the stem cells of the affected organ to renew. As a result of replacing old cells with new ones, a regeneration process takes place, thanks to which the organ is gradually restored.
