Overview

An allogeneic stem cell transplant uses healthy blood stem cells from a donor to replace your diseased or damaged bone marrow. An allogeneic stem cell transplant is also called an allogeneic bone marrow transplant.

A donor may be a family member, an acquaintance or someone you don't know. The blood stem cells used in an allogeneic stem cell transplant can be:

• Collected from the donor's blood
• Collected from the bone marrow within a donor's hipbone
• Collected from the blood of a donated umbilical cord

Before undergoing an allogeneic stem cell transplant, you'll receive high doses of chemotherapy or radiation to destroy your diseased cells and prepare your body for the donor cells.
