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.
Doctors also treat some blood diseases with stem cell transplants.In the past, patients who needed a stem cell transplant received a âbone marrow transplantâ because the stem cells were collected from the bone marrow. Today, stem cells are usually collected from the blood, instead of the bone marrow. For this reason, they are now more commonly called stem cell transplants. Why are bone marrow and stem cells important? A part of your bones called âbone marrowâ makes blood cells. Marrow is the soft, spongy tissue inside bones.
