Cord blood is the blood that circulates between the umbilical cord, the placenta and the fetus during pregnancy and which remains in the umbilical cord and placenta after the birth of the baby. The umbilical cord was always considered a wasteful product and was discharged.
This perception has now changed and cord blood has been recognized as a valuable source of stem cells.
The cord blood is a rich source of a specific class of stem cells, called progenitor hematopoietic stem cells. The basic characteristic of these cells is that they can generate all different types of blood cells, namely red cells, white cells and platelets
Because of this capability umbilical cord blood stem cells are worthy to be isolated and frozen for future use.
