More than 26,000 patients are treated with blood stem cells in Europe each year. Since the 1980s, skin stem cells have been used to grow skin grafts for patients with severe burns on very large areas of the body.
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.

Adult stem cells are the only stem cell type that has shown evidence of success when it comes to patients, and treating patients is supposedly the ultimate goal for stem cell research, certainly the justification for the huge sums of money poured into the field.
Why are stem cells called adult stem cells?
Non-embryonic (adult) stem cells. Adult stem cells have a misleading name, because they are also found in infants and children. These stem cells come from developed organs and tissues in the body. They’re used by the body to repair and replace damaged tissue in the same area in which they are found.

Induced pluripotent stem cells (iPSCs) Scientists have recently discovered how to turn adult stem cells into pluripotent stem cells. These new types of cells are called induced pluripotent stem cells (iPSCs). They can differentiate into all types of specialized cells in the body.
How old are embryonic stem cells?
Embryonic stem cells. Embryonic stem cells come from human embryos that are three to five days old. They are harvested during a process called in-vitro fertilization. This involves fertilizing an embryo in a laboratory instead of inside the female body. Embryonic stem cells are known as pluripotent stem cells.
What is stem cell?
Stem cells are undifferentiated, or “blank,” cells. This means they’re capable of developing into cells that serve numerous functions in different parts of the body. Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically designed ...
What is the purpose of red blood cells?
These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically designed to carry oxygen through the blood. All humans start out as only one cell. This cell is called a zygote, or a fertilized egg. The zygote divides into two cells, then four cells, and so on.
Where are hematopoietic stem cells found?
For example, hematopoietic stem cells are a type of adult stem cell found in bone marrow. They make new red blood cells, white blood cells, and other types of blood cells. Doctors have been performing stem cell transplants, also known as bone marrow transplants, for decades using hematopoietic stem cells in order to treat certain types of cancer.
