Abstract_ Background Excessive maturation of hematopoietic cells leads to a reduction of long-term proliferative capability during cord blood CB expansion. In this study we report the effects of anit-CD52 Alemtuzumab Campath on both short- and long-term ex vivo expansion of CB hematopoietic stem cells HSC by evaluating the potential role of Alemtuzumab in preserving the repopulating capability in CB HSC and nonlymphoid progenitors. Methods Ex vivo expansion experiments were carried out using .
