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).
(A few may also be found sporadically in the cecum and appendix.) They are identified microscopically by their location just below the intestinal stem cells in the intestinal glands (crypts of LieberkÃ¼hn) and the large eosinophilic refractile granules that occupy most of their cytoplasm.
