Addressing the misconceptions around donating stem cells

How stem cell donation works

How does donating my stem cells work?

Are you thinking about donating stem cells or bone marrow? The first thing you need to know is that 90% of stem cell donations do not require surgery. Rather, the stem cells are collected from the donor’s bloodstream – in a process that looks very similar to giving blood.

Only around 10% of donations nowadays are done via bone marrow – but this process isn’t as daunting as many people think. Compared to what people think when they hear “bone marrow harvest”, the reality of bone marrow donation is surprisingly simple. The procedure only takes around 30 minutes and bone marrow is collected from the pelvis via two small, superficial incisions.

Is stem cell donation safe?

Is it safe for me to donate my stem cells?

Both methods of stem cell donation are very safe and highly regulated. Once a potential donor is matched with a patient, there are strict guidelines in place to ensure the donor is safe and eligible to donate their stem cells.

Put simply: if it is not safe for you to donate stem cells, you won’t be asked to.

Is stem cell donation painful?

Blood stem cell donation (also known as PBSC or Peripheral Blood Stem Cell donation) is not typically painful. Donors usually report minimal discomfort, similar to that of a blood test.

Is bone marrow donation painful?

For bone marrow donation, the procedure itself is not painful as the donor will be under general anaesthesia. It is common, however, for the donor to experience some mild to moderate soreness, aching or stiffness for a few days to a couple of weeks afterwards.

Why do some people donate via blood and others via bone marrow?

The method of donation will be chosen by the doctor based on the needs of the patient. For example, bone marrow donation is often favoured for patients who are small children due to the high concentration of stem cells.

How long does it take to recover from stem cell donation?

Recovery after donating stem cells via PBSC

Most donors feel well enough to return to work, study, or other normal activities within 24–48 hours, although some choose to rest for an extra day.

Recovery after bone marrow donation

Most donors return to their usual routine within a few days to a week, although complete recovery can take two to three weeks for some people. The body naturally replaces the donated bone marrow within a few weeks.

Are there any long-term side effects after donating stem cells?

No, DKMS has facilitated over 135,000 stem cell donations over the last 35 years, and our medical teams have found no evidence of any long-term side effects to stem cell donations.

Donors typically recover within 1 to 2 weeks, depending on the method, and any stem cells or bone marrow lost in the donation process are naturally replenished by the body.
