What are Stem Cells?
Key facts
Stem cells are special cells produced in the bone marrow that can develop into red blood cells, white blood cells and platelets. A donor's stem cells can completely renew a patient's damaged or diseased bone marrow.
Which diseases does it treat?
Leukemia · Lymphoma · Aplastic anemia · Sickle cell disease · Thalassemia · Myeloma and 70+ blood disorders
Effect on the donor
In peripheral stem cell donation, 4-5 days of growth factor injections are given, followed by blood apheresis to collect the cells. In bone marrow donation, cells are collected from the hip under general anesthesia. Both methods are safe and stem cells regenerate within 4-6 weeks.
Frequently Asked Questions
Who can donate?
Individuals aged 18-55, weighing over 50 kg and in good general health can donate. Those without chronic illness or active infections are eligible candidates. A detailed eligibility assessment is carried out during the registration process.
How long does donation take?
The peripheral method involves 4-5 days of G-CSF injections and a 4-6 hour apheresis procedure. The bone marrow method involves a 2-3 day hospital process. Donors typically return to normal life the next day.
Is there a match guarantee?
No, there is no match guarantee. HLA tissue compatibility worldwide is approximately 1:500. However, the more registrations there are, the greater a patient's chance of finding a match. Increasing the number of Turkish donors is especially critical for ethnic diversity.
How do I register?
Free HLA typing can be done through Vena or by visiting TÜRKÖK/DKMS-affiliated centers. A simple cheek swab test is sufficient. All your information is kept confidential and you will only be contacted in the event of a compatible match.
Is donation painful?
In the peripheral method, flu-like symptoms (fatigue, bone pain) may occur during the G-CSF injection period; these resolve once donation is complete. The bone marrow method is performed under general anesthesia so no pain is felt; mild discomfort for a few days afterward is normal.
