What are the differences between bone marrow transplantation and blood stem cell transplantation?
The single most important difference is the source of the stem cells that give rise to mature blood cells in our blood stream. Bone marrow transplantation uses marrow-derived stem cells that live in our bone cavity. Marrow stem cells used in transplantation are obtained from the donor by removing a portion of the liquid marrow from the hip bone using a needle. This procedure is done in an operating room and requires some form of local or general anesthesia.
