A bone marrow transplant is done by transferring stem cells from one person to another. Stem cells can either be collected from the circulating cells in the blood (the peripheral system) or from the bone marrow.
Peripheral blood stem cells (PBSCs) are collected by an apheresis, a process in which the donor is connected to a special cell separation machine via a needle inserted in the vein. Blood is taken from one vein and is circulated though the machine which removes the stem cells and returns the remaining blood and plasma back to the donor through another needle inserted into the opposite arm. Several sessions may be required to collect enough stem cells to assure a chance of successful engraftment in the recipient. A medication may be given to the donor for about one week prior to apheresis that will stimulate the bone marrow to increase production of new stem cells. These new stem cells will be released from the marrow and into the circulating or peripheral blood system.
A bone marrow harvesting involves collecting stem cells with a needle placed into the soft center of the bone, the marrow. Most sites used for bone marrow harvesting are located in the hip bones and the sternum. The procedure takes place in the operating room. The donor will be anesthetized during the harvest and will not feel the needle. In recovery, the donor may experience some pain in the areas where the needle was inserted.

The previous poster points out the methods for obtaining stem cells from a Transplant Donor. In addition to routine testing of the blood to attain a match, a donor will need to be evaluated by a physician to make sure they are healthy enough to be a bone marrow donor.

Does testing hurt and what is the procedure?
Testing is as painless as giving blood, and only take 3-4 minutes. You give a tablespoon of blood and complete a National Marrow Donor Program (NMDP) consent form.

when I joined the military they requested if i had to donate. I suggested sure. they only took some blood. That changed into it. i'm particular in case you contact the pink flow they're going to direct you to the right position. I in spite of the indisputable fact that do not understand the entire technique of ways it really is extracted if you're ever a experience. Rumor is that it hurts, yet when you're saving someones existence i will do it. flow for it!!

generally, you will have an operation and they will go into your spine to extract some bone marrow along with adult stem cells from your spine.
it's a one time thing and you will be under sedation.

It not a big deal. They just test you for compatibility and it similar to giving blood. It not hard to do if you care about people. Try donating a Kidney!!!!! Ha! It different, but, you get over it.
