Hematopoietic stem cell gene therapy: a current overview.
Retrovirus-mediated gene transfer into murine hematopoietic stem cells and reconstitution of syngeneic mice have demonstrated persistence and functioning of the transgenes over extended periods of time. In contrast, clinically relevant levels of gene transfer into large animal and human stem cells have not been widely achieved. Results of current clinical gene transfer studies have raised fundamental questions about the physiology of primitive human hematopoietic cells and gene therapy vectors. Efforts are being undertaken to answer these problems and to develop more efficient gene therapy strategies.
