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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
