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.
And stem cells cloned from someone with a disease could be grown in culture and studied to help researchers understand the disease and develop treatments. In 2013, scientists at Oregon Health and Science University were the first to use cloning techniques to successfully create human embryonicstem cells. The donor DNA came from an 8-month-old with a rare genetic disease. Find out more about Stem Cells.
