What is stem cell transplantation?
Organ transplantation in general often means removing an organ and implanting it somewhere else where it can thrive and not die. This process can occur within the same body, between different bodies of the same species or even between some members of different species. In humans, only the first two types are done within the clinical practice -although tissues from animals may be used in limited procedures especially in heart surgery.
The blood is a tissue, and a blood donation is a form of tissue transplantation, but blood cells have limited time spans and need to be renewed via their stem cells located in the bone marrow. Stem cell transplantation solves this problem by introducing cells that will be able to divide into the body of the person in need of a permanent solution.
