Technology has made it possible to use stem cell for the treatment and prevention of medical disorders, conditions, and diseases. The treatment process involves replacing disease-damaged cells with fresh and healthy ones. Although the methods have shown a high degree of efficiency, they are being research and investigated further because they are relatively new. Researchers are also still working to come up with sources of stem cells that are more reliable.
The number of diseases that can be treated will increase once research into this treatment option is complete. However, at the moment, stem cell treatment centers can cure eye diseases, heart diseases, injuries, cancer, and diabetes among other conditions. Stem cell therapeutic techniques currently in use and under investigation are therapeutic cloning, and bone marrow, peripheral, and umbilical cord blood transplants.
Bone marrow therapy is the only most widely practiced form of therapy today. It has been in use for over thirty years and has helped in treating lymphoma and leukemia in cancer patients. The cells are mostly derived from adult donors and are kept in a frozen state until they are needed. A single donor can normally give up to 10, 000 doses.
One needs to understand some of the concerns involved in these therapies before going for them. Here are some of the concerns. Different stem cells are manufactured at different parts of the body during different stages of development. A perfect example is embryonic cells. These ones appear shortly after birth during the first stages. Others are manufactured and continue to exist in the body throughout the life of a person.
Specific stem cells are used for specific reasons by the human body. Tissue-specific cells have limited potential and only manufacture cells similar to those in the tissues they are found or derived. For instance blood is formed by specific kind of cell found in the bone marrow. The job of blood generation is only specific to that kind of cell and cannot be done by neural cells. For this reason, a single type of cells cannot be used to treat multiple unrelated conditions.
The many challenges that face this treatment option make it unsuccessful and unsafe. The first challenge is the high level of restriction imposed on it by various jurisdictions. Some qualities may be lost by the cells during culture because of the conditions they are subjected to. Loss of such qualities leads to modifications. Serious problems also arise from cells failing to behave as anticipated once in the body.
The techniques used for transplants are also very sophisticated and risky in themselves. Tissues have been known to get damaged by the method of transplant. The introduced cell may also be contaminated with viruses, bacteria, and fungi among other pathogens which may cause diseases in the body. Immune reactions from the body can also cause severe side effects.
The high costs involved in going for the therapies also inhibit people from attending them. Sometimes several therapy sessions are necessary for the treatment to be successful yet each session is very costly. The challenges named above need to be sorted out before the techniques are declared safe.
