Although worldwide experience with umbilical cord blood (UCB) transplantation is still relatively limited, clinical experience with UCB transplantation is encouraging. The use of UCB for hematopoietic stem cell transplantation (HSCT) has advantages and disadvantages. Among the advantages are rapid availability, ability to more rapidly schedule the transplant as the UCB units are stored and ready for use, the apparent reduced need for an exact human leukocyte antigen (HLA) match, and induction of a less severe graft versus host disease (GVHD) compared with bone marrow. The major limitation of reduced numbers of hematopoietic stem cells (HSC) in UCB is being addressed by basic research. It is promising that potential improvements in engraftment efficiency without increased stem cell numbers or actual increased stem cell numbers through dual UCB transplant or ex-vivo expansion might lead to improved treatment approaches. However, its therapeutic potential extends beyond the hematopoietic component suggesting regenerative potential in solid organs as well. Many different stem and progenitor cell populations have been postulated with potential ranging from embryonic like to lineage-committed progenitor cells. UCB derived MSCs have the differentiation capacity and also the therapeutic potential with regard to regenerative medicine, stromal support, immune modulation and gene therapy. Therefore, further advances are eagerly anticipated.
