Hi squirrellypoo,
Since the threads sometimes change so fast I didn't see your post about umbilical cord blood but now I have read it. Good that the study is considered to be "great news"!
You know patients that get umbilical cord blood still can get GVHD. In this study the cumulative incidence at day 100 of grade II–IV acute GVHD for the entire population was 29±3%. The 2-year cumulative incidence of chronic GVHD was 19%.
