So far, more than 35 000 cord blood transplants have been performed both in children and adults. In numerous cases, cord blood was used for the benefit of the donor’s sibling. Over the last two years, studies have revealed that cord blood stem cells have the capacity to differentiate into another type of cell e.g. muscle or nerve cells. Stem cells’ regenerative properties are currently the topical issue dominating the field of regenerative medicine. Stem cells were recognized as an invaluable biological material. More and more, research studies are committed to understanding stem cells’ full potential which could be applied in future to treat conditions such as: Alzheimer’s disease, diabetes, cardiac and liver disorders, muscular dystrophy, Parkinson’s disease, spinal cord injuries and strokes.
