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. You shall see so much promise in stem cell research, and even more controversy the subject can raise.
Stem cells are special cells in our bodies that can transform into different types of cells, for example, muscle cells, organ cells, as well as brain cells. There are two types of these cells, the embryonic stem cells, and adult stem cells. The embryonic stem cells come from unused human embryos, and are mostly used for research. These embryos are developed via in vitro fertilization. They can 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.
Seeing as stem cells can become other cells, stem cell therapy works to using them to replace ones damaged or dysfunctional. Here are cases in which this has been possible.
Cornea repair is possible for those whose corneas got damaged in an injury. 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 shall be applied in the development of new skin, which will, in turn, be used to cover those areas that had lost skin in the burn. There is even research going on to find ways to make the new skin to come with hair, sweat glands, and oil glands.
Stem cells also come in handy where there is a need to get rid of 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. Through stem cells regeneration, there shall be new dopamine-inducing neurons to replace the damaged ones.
Chemotherapy, while ideal for treating cancer, shall destroy even your stem cells. Once you finish your regimen, you need to have those cells reintroduced into your system. They shall be placed in the bone marrow, to grow and become healthy blood cells.
There are even more areas where stem cell therapy is beneficial, such as for treating the damage heart complications like heart attacks cause. These examples point out the need to support stem cell research. You shall learn more about the subject on this site.
