    Jump to navigation. For many years, researchers have been seeking to understand the body's ability to repair and replace the cells and tissues of some organs, but not others. After years of work pursuing the how and why of seemingly indiscriminant cell repair mechanisms, scientists have now focused their attention on adult stem cells. It has long been known that stem cells are capable of renewing themselves and that they can generate multiple cell types.

    What are Adult Stem Cells? | Adult Stem Cell Treatment

    Adult stem cells are undifferentiated cells , found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Scientific interest in adult stem cells is centered on their ability to divide or self-renew indefinitely, and generate all the cell types of the organ from which they originate, potentially regenerating the entire organ from a few cells. They have mainly been studied in humans and model organisms such as mice and rats. To ensure self-renewal, stem cells undergo two types of cell division see Stem cell division and differentiation diagram. Symmetric division gives rise to two identical daughter stem cells, whereas asymmetric division produces one stem cell and one progenitor cell with limited self-renewal potential. Progenitors can go through several rounds of cell division before finally differentiating into a mature cell.

    There are several ways adult stem cells can be isolated, most of which are being actively explored by our researchers. Adult stem cells have been found in the brain, bone marrow , blood vessels, skeletal muscle, skin, teeth, heart, gut, liver, and other although not all organs and tissues. They are thought to live in a specific area of each tissue, where they may remain dormant for years, dividing and creating new cells only when they are activated by tissue injury, disease or anything else that makes the body need more cells. Adult stem cells can be isolated from the body in different ways, depending on the tissue. Mesenchymal stem cells , which can make bone, cartilage, fat, fibrous connective tissue, and cells that support the formation of blood can also be isolated from bone marrow.
