Abstract

Irradiated mice were transplanted with cells containing a foreign gene to evaluate gene transfer and expression as a model for gene therapy. Using a uniquely safe and efficient retroviral packaging line developed in this laboratory (GP+E86), we demonstrate efficient and safe long-term transfer of the neomycin resistance (neoR) gene into mice. By infusing cells obtained from spleen colonies of primary post-transplant mice marked with the neoR gene into irradiated recipients, secondary and tertiary generations of recipient mice were produced. There was very low reconstitution activity of single stem cells in these successive generations of mice. We conclude that many more than one stem cell is necessary for successful long-term bone marrow transplantation in mice, presumably as a result of the relatively low frequency of stem cell cycling.
