Stem Cells and Reproductive Diseases

Stem cells are described as undifferentiated cells that are capable of reproducing themselves (self-renewal) and differentiating into many different cell types. There is great interest in stem cells because they have possible in the growth of therapies for replacing defective or damaged cells resulting from a variety of disorders and injuries, they are Parkinson's disease, heart disease, and diabetes. There are two types of stem cells they are embryonic stem cells, adult stem cells, they are also called tissue stem cells.

Embryonic stem cells (often referred to as ES cells) are stem cells that are defined from the inner cell mass of a mammalian embryo at a very early stage of development, when it is composed of a hollow sphere of splitting cells (a blastocyst).

Some of the tissues in the adult body are lining of the small intestine, and bone marrow, the epidermis of the skin, undergo continuous cellular turnover. Some kinds of tissue, are liver tissue, show minimal cell division or undergo cell division only when injured. In such tissues, there is probably no special stem-cell population, and any cell can participate in tissue regeneration when needed.

In humans, there are three known accessible sources of autologous adult stem cells: bone marrow, adipose tissue, and blood.  Just after birth Stem cells can also be taken from umbilical cord blood. Stem cell therapy is the make use of stem cells to prevent a disease or condition. Bone marrow transfer is a form of stem cell therapy that has been used for many years without controversy.

The benefits of Stem Cells are Stem cell treatments that may lower symptoms of the disease or condition that is being treated. The lowering of symptoms may allow patients to decrease the drug intake of the disease or condition. Stem cell treatment may also provide skill for society to further stem cell understanding and future treatments.
