Immunological evaluation of harvested stem cells obtained by leukapheresis after chemotherapy

Some patients suffering from malignancies may benefit of myeloablative chemotherapy followed by hematological reconstitution with autologous peripheral blood reinfusion. A quick evaluation of the number of hematopoietic progenitors present in leukapheresis blood samples is necessary to ensure the collection of a sufficient number of these cells. A study was performed on a series of 25 leukapheresis following initial chemotherapy.
