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.
Stem cellsâ value to researchers is that they can be induced into becoming specific tissue or organ cells. The cloning procedure works by combining a patient's body cell with an unfertilized egg cell from a donor. The patient's skin cell is inserted into the outer membrane of the egg cell and chemically induced to begin developing into a blastocyst. In the blastocyst, embryonic cells divide, producing a mass of stem cells. The stem cells can be induced to differentiate into different types of cells as needed (heart, nerve, muscle, etc.). These cells are genetically identical to the patient's own cells (that is, they are cloned).
