Why does graft versus tumor occur?
Graft-versus-tumor occurs when white blood cells from your donor (the graft) attack any cancer cells that remain in your body (the tumor) after high-dose treatments. This effect improves the success of the treatments.
What happens if you have graft versus host disease?
Graft-versus-host disease can occur when white blood cells from your donor (the graft) recognize cells in your body (the host) as foreign and attack them. This problem can cause damage to your skin, liver, intestines, and many other organs. It can occur a few weeks after the transplant or much later.

Why do you need an allo transplant?
For example, if you have cancer or another disease in your bone marrow, you will probably have an ALLO transplant because the replacement stem cells need to come from a healthy donor. Before your transplant, you might need to travel to a center that does many stem cell transplants. Your doctor may need to go, too.

How many cells are in an embryo?
Embryonic stem cells. These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.

How to identify HLA type?
The set of proteins, called the HLA type, is identified by a special blood test. In most cases, the success of allogeneic transplantation depends in part on how well the HLA antigens of the donor’s stem cells match those of the recipient ’s stem cells.
What type of transplants use stem cells?
In autologous transplants, patients receive their own stem cells. In syngeneic transplants, patients receive stem cells from their identical twin. In allogene ic transplants, patients receive stem cells from their brother, sister, or parent. A person who is not related to the patient (an unrelated donor) also may be used.
