Transplante de sangue de cordão umbilical - SCU

Abstract

The frequent use of umbilical cord blood as the source of hematopoietic stem cells, both in children and adults who do not have related donors, has led to the establishment of a better standardization of selection criteria aiming at improving the results. The choice of the umbilical cord blood unit should be based on the total number of nucleated cells and the number of differences in the human leukocyte antigen (HLA) system. When a unit has minimal cellularity, the use of a double cord blood transplant should be considered. When two or more units have similar characteristics, the choice may be determined by the CD34 count, ABO compatibility and the quality and speed to obtain the unit.
