“Researchers Believe Stem Cells Offer Great Promise For Medical Treatments”
What are Stem Cells?
Stem cells have properties that allow it to replicate into various types of cells in the body, including both multipotent and pluripotent cells. Pluripotent stem cells can stimulate the growth of any other cell in the body except those required to form a fetus.
Stem cells can also promote the growth of Multipotent cells which are beneficial in repairing the body. These cells have the ability to infinitely divide and replenish cells continuously as long as the person is living. Stem cell division allows each cell to remain a stem cell or mimic another cell as well as its specialized functions such as those of the blood cells, muscle cells, or brain cells.
The early life of stem cells allow them to grow into various cells in the body. They also serve important repair functions in tissues, which allow them to divide without the need to replenish other cells. This is one of the most remarkable properties of stem cells.
However, stem cells have two properties which separate it from other cells: the first is that they are unspecialized which have the ability to constantly renew themselves though division even after bouts of inactivity. The second is that there are certain factors such as physiologic conditions which may cause them to replicate into cells for tissues or organs and serve special functions.
Where do Stem Cells come from?
The bone marrow, eye retina and cornea, blood stream, dental pulp of the tooth, pancreas, skin, and liver are among the sources where mature stem cells may be derived. Pluripotent stem cells can be extracted from human embryos as long as it is only a few days in age.
Adult stem cells are the opposite of non-embryonic stem cells, and can be found in a number of tissues and organs. Each tissue contains a limited amount of multipotent stem cells which have restricted reproduction abilities. A stem cell niche houses stem cells, and is located in an area within each tissue, which may store the stem cells where they don’t divide unless activated by a need for more cells.
