The benefits of stem cells

Meets at conception, combines chromosomes 23-23 in the ovum and in the ovum, and forms the basis for a new start in life

At conception, it meets in the ovum and chromosome 23-23 in the ovum and forms the basis for a new start in life. During the first 14 days of conception, we can witness two important events. On the one hand, the oviducts of the ovary - where the two sperm are found on one another - the fetus starts to migrate to the uterus in about seven days, and then the next week is conceived for delivery. On the other hand, it begins to divide, so the fetal initiation is divided into two, then 4, 8, 16, 32 and so on. When fetal initiation is ingested in the uterus, it is made up of many parts - segments - like blackberries. Most importantly, however, from our point of view, the 30,000 genes in the 46 chromosomes of the cells that make up these segments are completely identical, meaning that no specialization has yet been made in the genetic material of the genes, the DNA macromolecule.

Fateful day

The 15th day of fetal development is crucial for the evolution of our lives. This is when the major body forms (head, stem, limbs, etc.) and organs (brain, heart, lungs, kidneys, testes etc.) begin to form, and accordingly the specific tissues and cells that make up them. However, these cells are fundamentally different from each other, since brain cells will have a role to play in thinking, while heart muscle cells must provide for cardiac function, thus maintaining blood circulation. Lung cells provide respiration, kidney cells provide urine output, and testicular cells provide onduction. All this can be achieved only by the fact that 3.2 billion nucleotides (also called letters) in the DNA macromolecule about 2 meters long transcend other DNA sequences in cells prepared for this specific task. That is, the cells of the blackberry fetus that have hitherto been able to develop into all-capable genetic cells specialized for a specific task. It's like youth, everything can be done with a child, but after school and job selection, we are only able to handle specialty jobs. And that's fine, because people can only meet the complex task of social work sharing. After all, the wonderfully multiplied activity of the human body can only be achieved by cells specialized in specific tasks.

Problems of organization

However, our lives are soon overwhelmed by illnesses, when the organs that perform the special task, and within it, the cells function and become incapable of delivering. Thus, the so-called pancreatic islet cells are unable to produce insulin due to disease, which is why diabetes develops. The calcification of the coronary arteries that carry the heart muscle can become so dead that it causes the heart muscle to remain bloodless and die (the so-called heart attack). And certain cells of the central nervous system may be responsible for Parkinson's and Alzheimer's disease.
Doctors have many things to do to improve the functioning of the organs or cells responsible for this disease, but the effectiveness of the treatments is limited. That is why there is an urgent need to recover or replace sick organs. Organ transplantation fulfills this need, but it is also a difficult task because of the immunological differences between people. Medicine - thanks in part to the wonderful new development of genetics - has now reached an opening in a new era, so-called stem cells, for this purpose.

Ethical procedure

Getting embryonic stem cells is very difficult. In practice, there is only one way to do this, and this is the flask method. In this case, more ova are removed from the prospective mother and these are "fertilized" in the "flask" so that the prospective father is able to fertilize with her offspring. After successful conception, the fetus begins to divide as it does in the pregnant body. At this point, the fetus starts from around 16-32 cells in the mother's womb. If the implantation is successful for the first time, more fetal initiation is maintained and stem cells can be obtained. However, the flask method provided a very limited amount of stem cells. And even the vast majority of professionals - not to mention members of the churches - find it unacceptable that due to the affordability of stem cells, they should "induce" fetal initiation in this way. Fortunately, scientific research has shown that, despite the specialization of organs, tissues, and cells that begin on day 15 of fetal development, these germ cells and cells are retained in the fetus, especially in the blood vessel system. The collection of stem cells from the genitive blood does not raise any moral problem, even though the head of the Catholic Church, the Pope of Rome, has welcomed his use.
Stem cells obtained from gonadal blood can be stored in a diminished state for a long time and have been used for bone marrow transplantation on numerous occasions. Recent research has found that there is also a way to achieve targeted specialization of these stem cells. Introducing these pancreatic islet cells into the patient's body, instead of treating diabetic patients with a life-long injection of insulin, would mean curing the disease.

Unlimited possibilities

Several human studies have shown that stem cell derived myocardial cells are able to enter into and recover from a heart attack after a heart attack. In animal experiments, the use of stem cells derived from the genital cord has also been found to be very important in Parkinson's and Alzheimer's disease. Thus, before medicine, a new and wonderful perspective can be given to the cure of bitter and transient diseases of human life.
Against this backdrop, it is becoming increasingly common for the stem cells obtained from neural lineages to be stored in the "banks" created there. After all, stem cells retained for 20 years or more can be very effective in treating neonatal, but adult or old age diseases.

    I accept it with pleasure. The question is interesting, I will also take part in the discussion. Together we can come to the right answer. I'm sure.

    Let's see

    I have not heard this

  4. Kihn

    it is obvious, you were not mistaken
