Stem cell therapy continues to receive a lot of focus from scientists and health organization worldwide as new methods of treating various diseases are researched. This therapy can be applied on animals and human beings to treat and prevent a multitude of medical conditions. Most therapies are still being researched and developed with only a few having been used successfully on live tissues on humans or animal models. So far, bone marrow transplant is the commonest therapy done by many stem cell treatment centers.
Bone marrow transplant has been advanced more than other therapies making it the most used. It helps to treat blood diseases like lymphoma and leukemia in people with cancer. Its research is still being done to achieve higher levels of efficiency and accuracy. In future, there will be treatments for heart diseases, deafness, missing teeth, diabetes, HIV AIDS, baldness, neurodegeneration, formation of blood cells, and infertility among many other conditions.
The sources of the cells employed in treatment are different and some are being criticized a lot by critics of science. Embryonic stem cells are the most widely used cells. They are isolated from embryos before they get cultured and prepared before they are used . According to critics, the methods used to acquire the cells promote human cloning and abortion. Other ways are induction of pluripotent stem cells and use of somatic cell nuclear transfer methods.
Treatments that base on transplanting of stored umbilical cord blood have faced a lot of challenges in marketing because of the wide criticism in this area. Many research facilities therefore face financial difficulties and shut down while researchers get discouraged by these difficulties and controversies. Some of the treatments are not complete yet because of these challenges.
Diseases destroy and kill cells reducing their numbers, stem cell therapy works to restore the lost or damaged cells in the area that is affected. When introduced into live tissues, they result in formation of new cells. This way, Parkinson disease, amyyotrophic lateral sclerosis, Alzheimer disease, and other brain degenerating diseases are curable and preventable. Similarly, wounds can be treated by formation of normal body tissues instead of typical scar tissues.
Many people have a lot of hopes in these treatments hence it is good to understand what they can do and what they cannot. First, it is worth knowing that the body has different types of stem cells and each type is specific to the function it does in human bodies. That is the reason why unrelated medical conditions cannot be treated by the same kind of cells. Tissue specific cells are specific in what they can do hence they cannot be used for functions they are not specialized for.
There is a lot of complexity in the methods used for introducing cells into human bodies. Besides the side effects, patients are faced with several dangers during the introduction process. Before the derived cells are returned into the body, the first have to be cultured. The cells are coded with instructions on how they should behave when introduced into live tissues. It is these instructions that present problems when they fail to work as expected.
The therapy is also a very expensive affair. It is therefore discouraging for most people to go for them due to lack of funds. Other medical options are therefore sort in its place.
