title: Hematopoietic stem cell expansion.
abstract: This review addresses two issues: (1) cytokine-mediated expansion of functional end cells for the abrogation of short term neutropenia and thrombopenia following high dose chemotherapy and (2) cytokine-driven increase in absolute numbers of functional stem cells. The literature suggests that the short term exposure of CD34+ cells to cytokines produces mature progenitors which in turn give rise to functional neutrophils and platelets. The expansion of functional stem cells is a more complex issue, as primitive stem cells are quiescent and their growth requirements are less clearly defined.
