Brief Summary
This is a pilot clinical trial to assess the feasibility and efficacy of expanding umbilical cord blood derived blood stem cells for transplantation using a combination of chemical factors and stromal co-culture. Bone marrow (BM) mesenchymal stromal cells (MSC) will be obtained from a separate bone marrow donor. One cord blood unit will be expanded by this method while another cord blood unit will be infused without manipulation. The expanded cord blood unit will help boost the initial recovery of blood counts after transplantation, though it is expected that the unexpanded cord blood unit will provide the cells which will lead to long term engraftment of blood stem cells. A third cord blood unit will be identified for standby should the cord blood unit expansion fail.
