 The goal of this study is to collect blood samples from the umbilical cords of newborn babies, as soon as they are delivered, and to place these samples in the MD Anderson Cord Blood Bank. Your sample may be included in the National Cord Blood Inventory NCBI which is part of the CW Bill Young Cell Transplantation Program. The NCBI is a federally-supported program to assist in the collection of cord blood. Cord blood will be made available to patients through The National Marrow Donor Program NMDP. These samples may then be offered to MD Anderson and other institutions for patients who need a bone marrow transplant and do not have a donor. The MD Anderson Cord Blood Bank will have the rights to release cord blood units to these institutions around the world according to established bone marrow transplant donor criteria, for a fee to cover costs.
