The Potential in Stem Cell Research

Stem cells are needed in regenerative medicine. This is seen where they are applied in the treatment of some complicated diseases and injuries. This matter of stem cell research offers both so much promise, and so much controversy.
Stem cells are unique dells in the human body capable of changing into different types of cells, such as muscle cells, organ cells, as well as brain cells. You will hear of two types of stem cells; embryonic stem cells, and adult stem cells. Embryonic stem cells come from unused human embryos, and are thus relied on for research purposes. Such embryos are gotten by the in vitro fertilization process. They have the ability to become many different types of cells. Adult stem cells, on the other hand, can only become one of two types. They are gotten from fully developed tissue, such as in bone marrow, skin and brain.
Since stem cells can become other cells, stem cell therapy focuses on using these cells to replace dysfunctional or damaged cells in tissues and organs. Here are cases in which this has been possible.
If your corneas were damaged before, you can have them repaired. Stem cells will be gotten from the limbus, that area of the eye between the iris and sclera. These will be multiplied in the lab thereafter. After they reach a good number, they can be transplanted back onto the damaged eye, thus restoring the patient’s sight.
Skin replacement after a life-threatening burn is now possible. Skin stem cells will be harvested and used to make new sheets of skin which will go to cover the areas damaged by the burns. The research currently is focused on finding ways to make the new skin have its own hair, sweat glands, and oil glands.
Stem cells have also been used to relieve the symptoms of Parkinson’s disease. Should the brain cells or neurons of the dopamine-producing areas of the brain degenerate, the patients will go through tremors, slow movement, the rigidity of the limbs, balance and gait issues, alterations in their speech and writing. When stem-cell regeneration happens, you will get new dopamine-inducing neurons to cover up the damaged ones.
Chemotherapy is used to treat cancer, but it leaves in its wake the destruction of your stem cells. When the chemo is over, it is important to have new stem cells put back into your body. They shall be placed in the bone marrow, to grow and become healthy blood cells.
You shall see more places where stem cell therapy is needed, like in treating the effects of heart conditions like heart attacks. These examples go to show why support for stem cell research is necessary. You may learn more about the matter on this site.
