Abstract
Retrovirus vectors allow efficient transfer of genetic material into cells. We describe an improved method for making cell lines which secrete broad host range retrovirus vectors in the absence of helper virus. This method was used to make virus-producing cell lines from several retrovirus vector constructions that encode dominant selectable markers. Virus titers from such lines exceeded 106 colony-forming units per milliliter of medium exposed to the cells. Cell lines that secreted certain vectors remained free of helper virus, while cell lines made using other vectors always secreted helper virus. Secretion of helper virus apparently depended on recombination between vector and the retrovirus packaging system, and factors involved in this event were investigated.
