Stem cells are very important cells of the human body.

Unlike most cells of the body, the life span of a stem cell exceeds that of the organism, while they retain the ability to divide. By multiplying, they can differentiate into other types of cells and thus replenish organs.

There are many different types of stem cells. In our company we focus on stem cells which are normally found in the bone marrow, the so called hematopoietic stem cells (or blood stem cells).

Since most of the cells circulating in blood have very short life spans, it is critical to have these stem cells constantly generating new blood cells. Blood stem cells are the source of all the different lineages of blood cells, including the red cells which transport oxygen, the cells which regulate the blood clotting system (“platelets”) and the white blood cells which constitute the immune system. As we age, so do our stem cells; they acquire genetic defects and become less functional.
