Abstract: A computer-based mixed-use cord stem cells registry system, method and device are provided for developing and maintaining a mixed-used bank of placental and umbilical cord stem cells and for the resultant bank. The cord stem cells, or a fraction thereof, is stored in a bank for the potential use of the donor and potentially the actual family of the donor child or from an unrelated person for whom the cord stem cells are a match. The system makes the cord stem cells available to the family until the blood sample is found to match a non-family member in need of the cord stem cells. At this time the family is given an option of keeping the sample for themselves or of providing it to the non-family member along with current information on the donor family.
