What are stem cells?
They are cells in the body which have the ability to divide and create more stem cells. They also have the ability to mature into specialised cells such as skin, heart tissue, brain cells, muscle or blood.
Embryonic stem cells are the earliest form of stem cells and can transform into many types of cells.
What are stem cell treatments?
These therapies use stem cells to replace or repair a patient's cells or damaged tissue. The cells may be injected into the blood, into the body through a lumbar puncture or straight into the damaged tissue.
The only fully tested and approved stem cell treatment is bone marrow transplantation.
What concerns are there about stem cell therapies?
This area of science is still very new and scientists say they still have much to learn about how stem cells work. Preparing stem cells for treatment can be difficult because unlike drugs they cannot necessarily be produced and tested for quality in large batches.
Scientists are still looking for the best ways of getting stem cells to the areas where they might have the best chance of repairing material. Side-effects could include cells growing in the wrong place or even causing tumors.
Why are stem cell treatments not yet widely available?
Much of the work is still at an early stage. As with all treatments, stem cell therapies have to be fully tested before they become widely available.
What should people consider when thinking about going overseas for stem cell treatments?
Experts say patients should be sure that there is good scientific evidence behind a treatment and that it will be safe and effective. The International Society for Stem Cell Research urges caution over the use of patient testimonials by companies.
Are there risks from stem cell treatments?
Patients should know exactly where the stem cells they are receiving have come from. There could be a risk of contamination and infection.
