Cell types and their characteristics

    Human body consists of 75-100 trillions of cells which are developed from fertilized egg (zygote). The zygote goes through several rounds of division with increasing the cell number.
    Blastocyst is one of the stages of embryonic development. It contains several dozens of cells, among which the distinct cell population occurs — inner cell mass or embryoblast. The embryoblast gives rise to all embryonic tissues and some non-embryonic organs (yolk sac, allantois and amnion).

    The blastocyst, when it is not implanted into the uterus tissue, is the particular stage to isolate embryonic stem cells. These cells have unique features – they proliferate and can maintain the undifferentiated state in vitro, besides, they have the potential to differentiate into all cell types of the body.

     Cells of an adult are on different stages of their development. There are some tissue types that renew their cell population constantly (blood, epithelium and others). The integrity of such tissues is maintained by a special cell type – adult stem cells.

     Adult stem cells are the undifferentiated cell population that restores the tissues' and organs' cell compound. Every tissue type has its own stem cells (hemopoietic stem cells, neural stem cells, muscle stem cells, epidermal stem cells and others) that repair and regenerate it. Adult stem cells have limited differentiation potential in comparison with embryonic stem cells. The number of adult stem cells is limited, and normally they are in dormant state. Their activation occurs in case of organ injure, for example.
Our laboratory


Development center cell research aimed at establishing and standardizing the collection of stem cells, multipotent mesenchymal stromal cells (ITC) and fibroblasts were the basis for the National Bank of stem cells and fibroblasts.

Stem cells - the body builders
                Cells of the human body are divided into ordinary and stem cells ordinary adult cells can not transform                 in another cell type , and can not induce embryogenesis . In humans,                 ninety allocated different types of cells , so the cells are those molecules                 which consists of an organism, stem cells and the organism is reduced . for                 storage of stem cells used Cryobank                 , Prior to entering the cell which is cooled in a freezer program steps                 one degree per minute. Thereafter, in special capsules , frozen to minus                 seventy degrees , the cells are placed into containers , numbered barcode                 in a special pot with liquid nitrogen , and our bank retains biological resources over 5500 patients.                 For storage of the concentrated stem cells and mononuclear cells derived from                 umbilical cord blood after birth, used Gemabank , there they are in special                 plastic plates and in order to highlight the desired cells are required for more                 manipulation. Longevity and beauty of a person   problem in the 21st century , which pay attention to not only women but also men and  successful resolution of this matter modern methods , such as cell technology allow a person to turn the modern ideas about resolving this problems . Learn more information about stem cell therapy you can in the appropriate section of our portal.
