If the patient continues to meet all criteria, the frozen cord blood will be shipped overnight to a special lab in Houston, TX for processing. Once release criteria have been met, the cells will be brought to the CMHH for infusion into the patient's vein. The patient will remain at CHMM for 24 hours of monitoring, after which they will be allowed to go home. Patients will be called daily by the research staff through Day 14, and once a month after that.
