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 is the only kind of stem cell therapy that is in wide use. It is employed in the treatment of blood diseases like leukemia in cancer patients. It has been in use for several years and continues to be researched further. In future, this therapy will be able to be used in the treatment of heart diseases, diabetes, HIV AIDS, deafness, missing teeth, baldness, neurodegeneration, infertility, and formation of blood cells among several other conditions.
Cells are derived from many different sources and some are under serious criticism. Embryonic stem cells form the bulk of all the cells used because they are easier to derive. They get isolated from embryos first before being taken through culturing and preparation procedures to ready them for use. Human cloning and abortion politics are highly stirred by these methods. Other methods include pluripotent stem cells induction and utilization of methods of somatic cell nuclear transfer.
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.
Therapy works through regeneration of damaged or lost cells in the affected area. Cells are introduced in the affected area where they stimulate formation of lost body cells. This effect has been determined to be able to treat conditions that lead to brain degeneration such as amyyotrophic lateral sclerosis, Alzheimer disease, and Parkinson disease. In the same way, normal body tissue can be generated to replace the typical scar tissue that forms on wounds.
Many people without understanding the technicalities of the therapies hold high hopes in them. First, one must know that different functions in the body are done by different kinds of stem cells. Therefore the functions of the cells are limited to specific tasks. Unrelated diseases cannot be treated by the same kind of cells. Tissue specific cells perform only the function they are specialized in or meant 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 also involves very high costs to be performed. This makes it unaffordable to most people. People therefore continue suffering because they cannot afford treatment.
