A method to increase the efficiency of transduction of hematopoietic and other cells by retroviruses includes infecting the cells in the presence of fibronectin or fibronectin fragments. The fibronectin and fibronectin fragments significantly enhance retroviral-mediated gene transfer into the cells, particularly hematopoietic cells including committed progenitors and primitive hematopoietic stem cells. The invention also provides improved methods for somatic gene therapy capitalizing on enhanced gene transfer, hematopoietic cellular populations, and novel constructs for enhancing retroviral-mediated DNA transfer into cells and their use.

Un método para aumentar la eficacia del transduction de células hematopoietic y otras en los retroviruses incluye la infección de las células en la presencia del fibronectin o de los fragmentos del fibronectin. El fibronectin y los fragmentos del fibronectin realzan perceptiblemente transferencia retroviral-mediada del gene en las células, particularmente las células hematopoietic incluyendo progenitors confiados y las células de vástago hematopoietic primitivas. La invención también proporciona los métodos mejorados para la terapia somática del gene que capitaliza en transferencia realzada del gene, poblaciones celulares hematopoietic, y construcciones de la novela para realzar transferencia retroviral-mediada de la DNA en las células y su uso.
