how can stem cells be used in disease treatment

Stem cells may therefore be very useful as a therapy for diseases in which organs are damaged or where the immune system is too active. Some types of stem cells are already used for therapy, such as the hematopoietic (blood) stem cells, which are used for the treatment of bone marrow

cancer.

How do stem cells help the cornea?

Clinical studies in patients have shown that tissue stem cells taken from an area of the eye called the limbus can be used to repair damage to the cornea – the transparent layer at the front of the eye. If the cornea is severely damaged, for example by a chemical burn, limbal stem cells can be taken from the patient, multiplied in the lab and transplanted back onto the patient’s damaged eye (s) to restore sight. However, this can only help patients who have some undamaged limbal stem cells remaining in one of their eyes. The treatment has been shown to be safe and effective in clinical trials and has now been approved by regulatory authorities for widespread use in Europe. Limbal stem cells are one of only three stem cell therapies (treatments utilising blood stem cells and skin stem cells being the other two) that are available through healthcare providers in Europe.
