Are cord blood stem cells different from other stem cells?
Yes. Umbilical cord blood stem cells are the “youngest,” safely available stem cells. Freezing these cells essentially stops the clock and prevents aging and damage that may occur to the cells later in life. Another source of stem cells, embryonic stem cells, has been at the heart of heated debate. Currently, embryonic stem cells are not being used to treat humans. A third category of stem cells are the adult stem cells, such as those found in bone marrow. Adult stem cells serve very specialized roles in children and adults and are not as proliferative as those found in cord blood.
