A stem cell can be imagined as a cell that doesn’t yet know what its job will be – it is not clear whether it will become a blood cell, a cell of any organ or tissue (skin, blood vessels, heart, muscles …). A baby’s body develops from stem cells; these cells are basic and non-specialist. Due to their ability to continue to specialize it is possible to use them later to cure or restore tissue damaged by disease. Today’s modern technology allows not only the collection but also the preservation of stem cells for decades and thereby preserves their potential for use in the future. Often this is a source of a significant chance for more fulfilling life.
