What is Bone Marrow Transplantation?
A bone marrow transplant (BMT) is a medical procedure that involves the replacement of unhealthy or diseased bone marrow with genetically healthy functioning bone marrow.
Types of Bone Marrow Transplant
Based on the source of the new bone marrows or the donor, there are two types of bone marrow transplant:
- Autologous Bone Marrow Transplant: In this technique, the patient is the donor. Doctors harvest healthy bone marrows before performing chemotherapy or radiation therapy. Once the bone marrow treatment is done, they inject back the bone marrow in the patient’s body again that helps to build and restore new marrows.
- Allogenic Bone Marrow Transplant: Bone marrow is extracted from a genetically compatible donor. A close relative or family member can be a suitable match for the transplant. However, in order to find the best match blood tests are conducted to find matching HLA.
- Umbilical Cord Blood Transplant: In umbilical cord blood transplant, the cells are taken from the umbilical cord of a newborn. Although the blood cells are still naive indicating that they are not active enough to attack other cells. It is a type of allogeneic bone marrow transplant.

Before performing a bone marrow transplant the following diagnostic tests are performed:
- Physical Examination
- Imaging Tests
- Bone Marrow Biopsy
- Blood Test
During the Procedure:
The procedure of a bone marrow transplant can be divided into three parts:
- Harvesting: The first part of the procedure includes bone marrow harvesting from the donor. It is collected from the hip bone as bone marrow concentrate is the highest here. Through the punctures made on the skin above the hip bone, the doctors extract bone marrow and blood through a special needle. Bone particles and fat are removed from the collection. The procedure takes about 2 hours.
- Conditioning: The next step includes chemotherapy or radiation therapy that destroys the damaged or diseased bone marrow in the patient’s body and suppresses the immune system. Conditioning is done so that new bone marrow can be produced once the donor bone marrow is introduced in the body.
- Transplant: After conditioning the patient is given a few days to rest so that the drugs can flush out of their system. Through a central line the donor bone marrow is injected into the patient’s body. As bone marrow transplant is a painless procedure, an anaesthetic is not provided to the patient.
After the Procedure
After the transplant, the patient has to stay at the hospital for a few weeks so that the new marrow settles and starts functioning. He/she have to go for frequent visits to the doctor so that his/her condition’s progress can be checked. Almost 6–12 months are required for a complete recovery after a bone marrow transplant. Till then the patient requires ample rest and be careful of infections.
