In Vivo Hematopoietic Stem Cell Transduction

Hematol Oncol Clin North Am. 2017 Oct;31(5):771-785. doi: 10.1016/j.hoc.2017.06.001.

Abstract

Current protocols for hematopoietic stem cell (HSC) gene therapy, involving the transplantation of ex vivo lentivirus vector-transduced HSCs into myeloablated recipients, are complex and not without risk for the patient. In vivo HSC gene therapy can be achieved by the direct modification of HSCs in the bone marrow after intraosseous injection of gene delivery vectors. A recently developed approach involves the mobilization of HSCs from the bone marrow into peripheral the blood circulation, intravenous vector injection, and re-engraftment of genetically modified HSCs in the bone marrow. We provide examples for in vivo HSC gene therapy and discuss advantages and disadvantages.

Keywords: Intraosseal; Intravenous; Mobilization; Viral vectors.
