Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. Until recently, researchers thought adult stem cells could create only similar types of cells.
The process of collecting (harvesting) stem cells for transplant depends on the source of the stem cells. Stem cells can be collected from bone marrow, circulating (peripheral) blood or umbilical cord blood. Stem cells from bone marrow. Stem cells are 10â100 times more concentrated in bone marrow than in peripheral blood. The hip (pelvic) bone contains the largest amount of active marrow in the body and large numbers of stem cells. Harvesting stem cells from the bone marrow is usually done in the operating room. The person will be given an epidural (spinal) or general anesthetic.
