What are Stem Cells?

apart are those cells that divide and give rise to others like them, can lead to different ones.

Stem cells retain the ability of early embryonic cells, since our body comes from the father's sperm unite with an egg the mother, forming a new cell from which it will form on the 220 different classes that exist in our body. There are stem cells that can cause all types of cells, while others are some of them or only those of the same or only those identical to them.

Where are you?

in the bone marrow is where leading mainly to blood cells, red blood cells, white blood cells and platelets also known as platelets. It has been observed also may lead to other types of cells. And not only stem cells found in bone marrow but have found in the fatty tissue in the muscle, brain, retina and pancreas.

How do I get?

cells were used for frozen embryo left over from in vitro fertilization and embryos that are formed by injecting the nucleus of a body cell into an egg, to which the element has been removed theirs. Those found in tejidosy órganoscitados are difficult to isolate and grow to multiply. More affordable are the of bone marrow and umbilical cord blood.

has managed to turn adult cells into stem cells of the body. This process is known as reprogramming, because it causes these cells will reverse and return to have the same properties when they were embryonic and could lead to different kinds of cells. To achieve this end they introduced genes to cells of the mother's overwhelming. The reprogrammed cells are called iPS cells (original English meaning: induced, and pluripotent stem cells) and have the advantage of not causing moral problems as with those obtained from embryos.

How important?

Their study will clarify the mechanisms of the organism's development. Observe the effect of drugs before using the sick. And most importantly, to cure certain diseases, which currently give clear results in Leukemia, certain anemias, in repairing heart muscle after heart attack, difficult to repair bone fractures. Experienced in diabetes, Crohn's disease, multiple sclerosis, fistulas, corneal opacity, rheumatoid arthritis, lymphoma, Parkinson's disease and Alzheimer's.
