Why Preserving Umbilical Cord Blood?

After baby is born, the umbilical cord is cut and discarded with the placenta. The blood in the vessels of the cord and placenta is rich haematopoietic stem cells and can be collected before being discarded. Transplantation of haematopoietic stem cells is the only available treatment for immune and blood system disorders such as lymphomas, and leukemias. To this end first the sick cells are destroyed via chemotherapy or radiation therapy. The patient then receives stem cells that repopulate the bone marrow with healthy cells.
