Abstract
This invention relates to cell lines, particularly mammalian cell lines, established by transforming the cells with vectors, preferably retroviral vectors, containing two or more oncogenes under the control of one or more inducible promoters and/or genetic elements. Also within the scope of the invention are human cell lines with extended in vitro lifespan, transformed by vectors containing one or more oncogenes under the control of one or more, preferably exogenous, inducible promoters and/or genetic elements. The vectors may additionally contain gene(s) encoding for desired gene product(s). Also disclosed are insulin producing human pancreatic cell lines useful for transplantation into human diabetic patients.
