Stem cell therapy is the use of genetically engineered stem cells to treat or prevent an illness or disorder. The only current treatment using genetically engineered stem cells is embryonic stem cell transplantation. It typically occurs as an umbilical cord-blood transplant, but the stem cells can also be derived from umbilical cord plasma. There are many issues with stem cell treatments. It is recommended to consult with a professional genealogist before considering any type of stem-cell treatment. Although there has been some doubts about embryonic stem cells transplants’ ethics however, research has shown that they are extremely secure and many children have had success with stem cell treatment for their genetic disorders.
Scientists have discovered that some patients can be treated using stem cells and chemotherapy simultaneously. The patient’s ability and willingness to take on the stress of ongoing treatment is crucial to the success of this procedure. Researchers have been able to treat some patients with one transplant. Then, they gave the patient one dose of chemotherapy. With advances in medical science scientists have discovered that a person’s tolerance to stress can affect the efficacy of chemotherapy drugs they are taking. Researchers are currently testing new chemotherapy drugs for use in combination.
Scientists are still working on stem cell transplants. They are also studying different ways to utilize genetically engineered blood to treat chronic illnesses like leukemia and multiple sclerosis. Stem cells are living tissues that have been re-engineered to repair and replace damaged body parts. The donor’s skin or bone-marrow is a good source to provide more stem cells to areas that is most in need.
In addition to using stem cell transplants, scientists are investigating other treatments that utilize specially bred, specialized cells. One group is studying the effects of exposed pregnant mice to high doses of radiation. The mice were not exposed to radiation at all, but were exposed to extremely high levels of radiation. The mice survived but only for a short amount of time. The mice could require several months of treatment to heal because these specialized cells aren’t well absorbed by the body.
Scientists are also investigating the effectiveness of immune system boosting with stem cell treatments. Interferon is one of the most sought-after immune system boosters. Interferon can be used to treat a variety of types of cancers, such as lymphoma and blood cancers. Researchers believe that stem cell treatments could have adverse negative effects that could be mitigated by increasing the immune system.
Scientists are also investigating the effect of diet in slowing down the aging process. They are studying diets that have ingredients that help in the production of healthy cells. These are substances are referred to as antioxidants. When they are created by our bodies, these substances can repair tissue damage. Some of the substances that are being studied by researchers are phytosterols, lecithin, and lipoic acid.
Of course, scientists haven’t yet fully understood the exact effects of stem cell transplants. They are aware that the number of transplants carried out is less than what is needed to treat a heart disease. Scientists can see the overall benefits to patients if they can create an individualized diet, exercise, transplant that will result in a more youthful, healthier heart. Stem cell transplants are an extremely effective treatment option as it can give patients an opportunity to live afresh.
Other researchers are researching methods that are less radical and employing techniques similar to therapeutic cloning. In this instance, there is no direct human contact between the donor and recipient. Cloning involves taking DNA from other people and inserting the nucleus of these cells into the egg of the recipient. If it is successful, could be used to generate the cells needed to power the immune system.
