Stem Cell Research
Stem cells are needed in regenerative medicine. This is due to their critical role in the treatment of many complex 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. There are two types of these cells, the embryonic stem cells, and adult stem cells. Embryonic stem cells originate from unused human embryos, and serve well in research. Such embryos are gotten by the in vitro fertilization process. They can become many different types of cells. Adult stem cells cannot change as much as the embryonic ones, as they have only two options. They are gotten from fully developed tissue, sources being the bone marrow, skin, and brain.
Seeing as stem cells can become other cells, stem cell therapy works to using them to replace ones damaged or dysfunctional. Here are examples of how that has been done.
If your corneas were damaged before, you can have them repaired. Stem cells shall be harvested from the limbus, that area of the eye between the iris and sclera. They shall then undergo multiplication in the lab. After they reach a good number, they can be transplanted back onto the damaged eye, thus restoring the patient’s sight.
There is now replacement of skin for those who have gone through a life-threatening burn. Skin stem cells shall be used to grow sheets of new skin, which shall then be used to cover areas that lost skin in the burn. 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. In cases where the dopamine-producing regions of your brain have their neurons damaged, you will suffer 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 may be necessary for treating cancer, but it leaves you with destroyed stem cells. When the chemo is over, it is important to have new stem cells put back into your body. They will go to the bone marrow, to grow and develop into healthy blood cells.
There are more places stem cell therapy is needed, such as in handling the damage heart diseases come with. These examples go to show why support for stem cell research is necessary. You shall learn more about the subject on this site.
