Since ATP production yields a fuel currency that is used by every process in the body, it is important to consider this in your dietary plan. There are a lot of supplements that are engineered with this particular concern in mind.
By this definition, stem cells are particularly important for plant growth, because virtually all tissues of the plant descend from small groups of stem cells located in their growing apices, within structures called the apical meristems (Sablowski 2004; Scheres 2007) (Figures 1 and 2).
Definition. A stem cell is a generic cell that can make exact copies of itself indefinitely. A stem cell has the ability to make specialized cells for various tissues in the body, such as heart muscle, brain tissue, and liver tissue. Stem cells can be saved and used later to make specialized cells, when needed.
