Ex Vivo Hematopoietic Progenitor Cell Expansion

Abstract

The ability to culture and expand hematopoietic progenitor cells ex vivo has major implications for both bone marrow and stem cell support following marrow ablative or subablative high-dose therapy and for improving the efficiency of retroviral transfection in gene marking and gene therapy. This review focuses on methods for the generation of myeloid progenitor and post-progenitor cells from peripheral blood stem cell collections, with particular emphasis on the characterization of these cells and practical issues associated with their expansion.
