Cord blood refers to the blood that remains in the umbilical cord and placenta after a newborn's umbilical cord has been clamped.
According to the latest medical discoveries, cord blood can treat many blood system diseases. However, a single unit of cord blood is only enough for one stem cell transplant for children under the age of 10. Even if Caitlin Carter gave birth to a child, the cord blood would not suffice, and they would still need to search the blood bank for other matching cord blood. Moreover, finding a suitable match is extremely difficult, as cord blood has higher compatibility requirements than bone marrow.
Old Mrs. Simonson clung to the idea of cord blood as if it were a lifeline, gripping Caitlin Carter's shoulders and desperately shaking her, forcing her to have children.
Caitlin Carter sobbed uncontrollably, unable to utter a single word.
