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).
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
