There are two methods for obtaining stem cells: peripheral stem cell donation and bone marrow donation. In most cases, the stem cells required for treatment can be obtained from the blood via peripheral donation:

Peripheral stem cell donation: The stem cells are collected from the peripheral blood system using two cannulas and a cell separator connected between them. This takes 4-6 hours and is performed on an outpatient basis, i.e., the donor goes home after the donation. In preparation for the donation, several preliminary examinations are necessary, as well as the administration of a growth factor over 4 days prior to the donation to mobilize the stem cells from the bone marrow.

Bone marrow donation: Only one in ten donations is a bone marrow donation. This is done by puncturing the iliac crest, where the stem cells are taken directly from the bone marrow. The donor is given a general anesthetic, so an overnight stay in hospital is necessary. The bone marrow donation takes about 45-60 minutes. Some preliminary examinations are necessary
