title: Gene therapy of hematopoietic stem cells: strategies for improvement.
abstract: Gene therapy of hematopoietic stem cells (HSC) is limited by low frequency of the target cells, their quiescent nature, poor engraftment of treated HSC, and lack of a selective growth advantage of genetically modified cells. Lentiviral vectors combined with positive selection strategies using conditional cell-growth switches should allow for improvement.
