Haploidentical stem cell transplantation: T cell depleted and repleted

Allogeneic hematopoietic stem cell transplantation (AHSCT), is a curative treatment option for many hematological diseases. Donor availability is the major limiting factor in the transplantation setting. More than half of the patients do not have a HLA fully matched related/unrelated donor but almost all patients have an haploidentical donor. Haploidentical transplantion can be performed either as T cell depleted or repleted. Despite the promising results in T cell depletion methods, expensive T cell selection and the necessity for experienced staff seem to be the limiting factors. However, a T cell repleted haploidentical stem cell transplantation strategy is simple, cheap and has been preferred by different transplant centers worldwide.
