Become a donor

Be Part of a Global Team of Life-Savers

Every year, thousands of people get really sick from blood cancers or genetic diseases. For many of them, the only chance to get better is a transplant of stem cells, bone marrow, or cord blood. But here’s the problem: finding the right match is not easy. It’s even harder for people with mixed heritage or from ethnic minority groups, because for them there are fewer matches in the WMDA global database. By signing up as a voluntary stem cell donor, you might change the odds for someone who needs help to survive. And one day you could get the call because you are the perfect match for a patient in need.

There are three ways to donate:

icon_bone_marrow

Bone Marrow Collection

  • A short medical procedure where doctors collect stem cells from your pelvis under anesthesia.
  • It’s very safe, with risks similar to those of general anesthesia.
  • Most donors recover in a few days, with minor side effects like fatigue or bruising.
icon_peripheral_blood

Peripheral Blood Stem Cells Collection

  • A safe, common method where you get daily injections for a few days to increase stem cells.
  • The cells are collected from your blood—similar to donating plasma.
  • Side effects are usually mild (like flu-like symptoms) and go away quickly.
  • Serious complications are very rare (less than 1% of cases).
icon_umbilical_cord-1

Umbilical Cord Blood Collection

  • After a baby is born, the placenta and umbilical cord still contain valuable stem cells.
  • This cord blood can be collected, frozen, and stored for future transplants.
  • Collection is completely safe and painless for both the mother and baby.
  • Parents can choose to donate their baby’s cord blood to a public bank to help patients in need.
