        Retroviral Transduction of Hematopoietic Progenitors Derived From Human Embryonic Stem Cells

        It has been recently identified that cytokines and BMP-4 promote hematopoiesis from human embryonic stem cells (hESC) and that, before hematopoietic commitment, a rare subpopulation of cells lacking CD45, but expressing PECAM-1, Flk-1, and VE-cadherin (hereinafter termed CD45neg PFV precursors), are exclusively responsible for hematopoietic cell fate on cytokine stimulation. Efficient strategies to stably transduce these hematopoietic precursors specifically generated from hESCs would provide a novel and desirable tool to study hematopoietic development through the introduction and characterization of candidate genes suspected to regulate self-renewal processes of hESC-derived hematopoietic cells or dynamically track hESC-derived hematopoietic stem cells in vivo. To date, only transient transfection and stable transduction using lentiviral vectors have been reported in undifferentiated hESC followed by random and spontaneous differentiation into different cell types. However, protocols for stable transduction of hematopoietic progenitors prospectively derived from hESC need to be developed yet. In the present chapter, we described detailed methods on the recently characterized and optimized GALV-pseudotyped retroviral gene transfer strategy to stably transduce the hematopoietic progenitor cells prospectively derived from CD45neg PFV hemogenic precursors as a vital tool to study hematopoietic development and to characterize candidate genes suspected to eventually confer robust and sustained repopulating ability to hESC-derived hematopoietic cells.
