The mitochondrion produce a substance called adenosine triphosphate. It is also known as ATP. It is believed to be our source of energy. ATP's main purpose is to transport chemical energy within cells for metabolism[2]. Metabolism is the sum of the physical and chemical changes that take place in living organisms.
Stem cell harvest. Stem cells used to be harvested from the bone marrow. That has now largely been abandoned in favour of harveting directly from the peripheral blood.
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.
