The Watchtower 15th May 1984 page 31 under the heading 'Questions from Readers'' says
· ''Could a Christian accept a bone-marrow transplant, since blood is made in the marrow?
As the question itself notes, red blood cells are formed in the marrow of certain bones such as the ribs, sternum and pelvic bones. Hence, it is understandable why, in the light of the Bible's prohibition on blood, the question arises whether a Christian could accept a graft of human bone marrow.
The Bible states clearly that God's servants must 'abstain from blood.' (Acts 15:28, 29; Deuteronomy 12:15, 16) But, since red cells originate in the red bone marrow, do the Scriptures class marrow with blood? No. In fact, animal marrow is spoken of like any other flesh that could be eaten. Isaiah 25:6 says that God will prepare for his people a banquet that includes "well-oiled dishes filled with marrow." Normal slaughtering and drainage procedures never drain all blood cells from the marrow. Yet once a carcass is drained, then any of the tissue may be eaten, including the marrow.
Of course, marrow used in human marrow transplants is from live donors, and the withdrawn marrow may have some blood with it. Hence, the Christian would have to resolve for himself whether-to him-the bone-marrow graft would amount to simple flesh or would be unbled tissue. Additionally, since a marrow graft is a form of transplant, the Scriptural aspects of human organ transplants should be considered. See "Questions From Readers" in our issue of March 15, 1980. Finally, writing in Harrison's Principles of Internal Medicine (Update I, 1981, page 138), Dr. D. E. Thomas observes that "virtually all marrow transplant recipients will require platelet transfusions" and many are given "packed red blood cells." So the Christian should consider what additional issues he would have to face if he submitted to a marrow transplant.-Proverbs 22:3.
Though a personal decision has to be made on this matter, the Bible's comments about blood and marrow should help the individual to decide.''
Bone marrow Transplant
Some types of procedures that doctors use umbilical cord blood for is bone marrow. If the baby needs more bone marrow, they can get some extra from blood from the umbilical cord.
Packed bone marrow refers to bone marrow that is densely concentrated with cells, such as stem cells and blood-forming cells. This type of bone marrow is typically found in areas such as the pelvis or femur bones in adults. Harvesting packed bone marrow can be beneficial for procedures such as bone marrow transplants.
These procedures include a complete history and physical, blood tests, chest x rays, and bone marrow biopsy.
A group of scientists discovered cord blood stem cells in 1988 after searching for other procedures that have lesser GvHD effect. The harvest procedures are also easier compared to bone marrow.
The tissue found in bones that makes blood cells is called bone marrow. There are two types of bone marrow: red marrow, which is responsible for producing red blood cells, white blood cells, and platelets, and yellow marrow, which is primarily composed of fat cells. Hematopoiesis, the process of blood cell formation, occurs within the bone marrow through the differentiation of hematopoietic stem cells.

This procedure is known as a bone marrow biopsy - A needle puncture to obtain a sample of bone marrow, usually from the ilium, for study; used to diagnose, stage, and monitor disease and condition of the blood cells
Red Marrow, and Yellow Marrow.

You could be anesthetized for a bone marrow biopsy if you request it strongly enough. I believe in general that people are heavily sedated with strong local anesthetic prior to this procedure anyway since it is relatively painful.
