US Patent 7303911 Prostate cell lines

An increasingly aged population and better diagnosis has lead to an apparent increase in the prevalence of prostate cancer in men. There is an acute need to better understand the progression of this disease from its locally confined site of initiation to the end stage widely metastatic disease with attendant morbidity and mortality, It has historically been difficult to raise and maintain immortalized prostate cell lines in culture. We have derived a cell line selected from the group consisting of clones ONYCAP 1 and ONYCAP23. The cell lines are characterized as being prostate epithelial in origin.
