The umbilical cord and the blood left in it at birth contain a broad diversity of pristine newborn stem cells that have demonstrated the ability to help other tissues and organs heal themselves after injury or disease. Hematopoietic stem cells found in cord blood used for 20 years to help regenerate the body's blood and immune system. Mesenchymal stem cells, found primarily in the umbilical cord tissue itself, have the ability to help from bone or connective tissues like cartilage and ligaments.
Stem cells from the umbilical cord and cord blood have distinct benefits compared to adult stems cells from bone marrow. They're younger, have greater ability to multiply, and have had minimal exposure to environmental factors like viruses or chemicals that can interfere with cell structure and function.
Cord blood stem cells are not embryonic stem cells. Collecting and using them is not controversial.
