Past and Present of Cord Blood Transplants 1989 First Cord blood transplant 1989-92Clinical observation that GVHD was reduced in HLA incompatible CBT 1992-93 Establishment of Cord blood banks (NY, Paris, Milan and Dusseldorf ) 1993-95 Feasibility of HLA incompatible unrelated cord blood transplants 1995 Establishment of Eurocord group 1997 Nucleated cell dose more important factor for engraftment and survival , influence of HLA on engraftment 1998 Large series of UCBT = confirmation of cell dose and HLA >2000Retrospective comparisons between UBMT and UCBT 2002 Use of cord blood cells in adults with promising results 2003 Criteria of cord blood choice and indications 2003-04 Use of double cord and RIC regimen in adults 2004 Isolation of USSC from umbilical cord blood 2004-05 Comparable results between unrelated CBT and UBMT in adults

  12. Indications of cord blood banking for family use • Sibling with a disease which can be cured by hematopoietic stem cell transplantation: Poor risk leukemia, aplastic anemia, hereditary disorders. • HLA mismatched transplants with 1, 2 or full haplotype (?) • Familial predisposition to malignancies • Genetic disease (autologous use for gene therapy)
