What are stem cells

The concept of "stem cells" first appeared in Russia at the beginning of the last century. A.A.Maksimov pathologist studying the process of hematopoiesis, came to the conclusion that they exist. What are these cells and what are their distinguishing features?

Stem cells can give rise to any cells in the body - and the skin, and nerve and blood cells.

Stem cells can be isolated and grown in tissue culture. The ability to provide a wide variety of cell types of stem cells makes an important reserve for reducing the body, which is used to fill defects arising due to various circumstances.

Stem cells can transform into cells of all types of tissue: blood cells, internal organs, muscle and bone tissue, skin, neurons, etc. In the early stages of its development, the human body is almost entirely composed of stem cells, which gradually acquire specialization, that is, from They form the organs and tissues of the body. Thus, stem cells are, first, a kind of building material of the body. Also, they take a direct part in the regenerative processes in the body and may slow the aging process. Because of the ability to transform into cells of all organs and tissues of the stem cells play the role of "first aid": If the problem somewhere in the body, stem cells are sent back and replace lost due to disease or damage to the cell body regains its function. With age, the number of stem cells is reduced, and the regenerative potential of the body are reduced.

The use of stem cells to treat and prevent a wide range of diseases has led to active development of cellular technology. Medicine does not stand still, and soon many diseases, especially considered incurable, can be cured with stem cells.

Stem cells are used for different purposes, the main of which - this treatment and cosmetology.

In order to use stem cells in these and other purposes established clinics and medical centers in Russia and abroad. But we must remember that not all of these clinics and medical centers are licensed to use stem cells.

Umbilical cord blood - a valuable source of stem cells. Umbilical cord blood is collected in sterile conditions and stored in special banks of stem cells (cryobanks), making it easier and faster to obtain stem cells.
