Delivery of RNA-based molecules to human hematopoietic stem and progenitor cells for modulation of gene expression

Abstract

Gene modulation of human hematopoietic stem and progenitor cells (HSPCs) harbors great potential for therapeutic application of these cells and presents a versatile tool in basic research to enhance our understanding of HSPC biology. However, stable genetic modification might be adverse, particularly in clinical settings. Here, we review a broad range of approaches to transient, nonviral modulation of protein expression with a focus on RNA-based methods. We compare different delivery methods and describe the usefulness of RNA molecules for overexpression as well as downregulation of proteins in HSPCs.
