Overview

A bone marrow transplant is a procedure that infuses healthy blood-forming stem cells into your body to replace your damaged or diseased bone marrow. A bone marrow transplant is also called a stem cell transplant.

You might need a bone marrow transplant if your bone marrow stops working and does not produce enough healthy blood cells.

Bone marrow transplants may use cells from your own body (autologous transplant) or from a donor (allogeneic transplant).
