In the near future, stem cell treatments could relegate them to history. Those are not the only conditions that may end up being cured by the groundbreaking research--there also are kidney disease. Stem cell research offers unprecedented opportunities for developing new medical therapies for debilitating diseases and a new way to explore fundamental questions of biology. Stem cells are unspecialized cells that can self-renew indefinitely and also differentiate into more mature cells with specialized functions.
Stem cells are undifferentiated, non-specific human cells with a full complement of DNA that have not yet transformed into anything specific, such as the cells in your hand, or the cells in your hair follicles. These cells are capable of being a mechanic for your body; they can repair you by undergoing cell division to manufacture whatever cells are needed in order to replace old, damaged, or diseased cells that are no longer viable and need to be replenished.
Stem cell lines, once isolated, are very easy for scientists to work with because they can continue to make these cells for testing from the original line, due to the fact that those original lines are basically immortal, providing scientists with an unlimited supply that they can use for experimentation.
Currently, stem cell treatments are not available for most conditions and are usually only utilized in bone marrow transplants and not much else. The primary challenge that researchers face, as they attempt to perfect the usage of these treatments, is to prevent the immune system of the patient from rejecting the injected cells. A similar dilemma occurs with organ transplants, as the immune system of the recipient can reject the donation.
There have been a few successful, high risk experiments that utilized stem cells to reverse a debilitating condition. One of the most noteworthy examples occurred within the past 2 years, as scientists injected cells into the area where a test patient had been suffering from acute arthritis, and the results were astonishing. The cells divided into healthy joint cells that integrated themselves into the inflamed area and reversed the arthritic condition.
Stem cells will ultimately be the final frontier of medicine, providing cures for diseases that scientists have struggled with for years, such as Alzheimers, heart disease, and organic brain disease. However, there is much opposition to the research. Prominent religious leaders and idealogues are opposed to the research.
The religious right feels that creating an embryo to do research is tantamount to abortion. However, if the research is to reach its full potential, the creation of further embryos will be a necessity in order to support adequate research.
Research on human embryonic stem cell is controversial in our society about the moral and legal status of the early embryo. The controversy allways be encourage provocative and conflicting claims both inside and outside the scientific community about the biology and biomedical potential of both adult and embryonic stem cells.
