Stem cells have the ability to transform into hundreds of cell types, they form the organs and tissues, they have the ability of self-renewal, and they can replicate themselves. The decrease in blood cells may be life threatening for the patients.
Stem cells reside in bone marrow to form new blood cells. Stem cells can be obtained from bone marrow, blood, or umbilical cord for transplantation. The bone marrow is completely or partly evacuated for stem cell transplantation.
