An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium.
Since the initial discovery that the adult brain contains stem cells that generate new neurons, an important question in neurobiology has been whether or not this adult neurogenesis is functionally important.
Somatic stem cells (also called adult stem cells) exist naturally in the body. They are important for growth, healing, and replacing cells that are lost through daily wear and tear. Potential as therapy. Stem cells from the blood and bone marrow are routinely used as a treatment for blood-related diseases.However, under natural circumstances somatic stem cells can become only a subset of related cell types. Bone marrow stem cells, for example, differentiate primarily into blood cells.omatic stem cells (also called adult stem cells) exist naturally in the body.
