A cord blood bank is a facility that collects, processes, and stores umbilical cord blood, which is rich in stem cells. These stem cells can be used in medical treatments for various diseases, including certain types of cancer and blood disorders. Parents can choose to donate their baby's cord blood to a public bank or store it privately for their family's future use. The process of banking cord blood is simple and safe. After a baby is born, the umbilical cord is clamped and cut, and the blood remaining in the cord is collected. This procedure does not harm the baby or the mother and can provide valuable medical resources for future therapies.
