Figure 3 Cumulative incidence of 3-year TRM after UCBT. Data are shown by TNC dose (A), HLA-mismatch (B), TNC dose and HLA-mismatch combined (C), and the Kaplan-Meier probability of disease-free survival (D). Recipients of units with either 1 or 2 mismatches were analyzed by separate TNC-dose categories, whereas recipients of zero mismatched units and three mismatched units were not.

Figure 4 Cumulative incidence of leukemic relapse by positive (solid line) vs. negative (dotted line) proliferative response status to the herpes viruses (cytomegalovirus, herpes simplex virus, varicella zoster virus) (p = 0.003). Those with antigen-specific proliferative responses to any of the three viruses at any time during the 3-year observation period were considered positive. Reprinted from Parkman R, Cohen G, Carter SL, et al. Successful immune reconstitution decreases leukemic relapse and improves survival in recipients of unrelated cord blood transplantation.

Figure 5 Human cord blood as a stem cell source for cell-based regenerative therapies. Human cord blood is now routinely used as an autologous or allogeneic HSC source to treat both malignant and nonmalignant diseases. Cord blood mononuclear cells and enriched stem cell populations have both shown great potential in preclinical cell-based therapies for various degenerative diseases such as stroke and myocardial infarction. Cord blood contains multiple populations of tissue stem cells and progenitors, as well as primitive stem cells, which can further be differentiated to cells representative of all three embryonic germ layers. These primitive stem cells can therefore be a potential alternative to ES or iPS cells for the derivation of somatic cells for tissue regeneration.
