Isolated cells from eyes have become an increasingly important tool in eye disease research. With these cells, controlled experiments on mechanisms of, and potential therapies for, eye disease can be conducted. To date, many studies have used the RPE cell line ARPE-19, but propagating and sustaining cell lines such as this is time-consuming and expensive. Also, obtaining human eyes suitable for culture is difficult.
Solution
A novel, immortalized mouse RPE cell line has been developed. Cells derived from mouse models are advantageous in that the RPE cells are more readily obtained, their supply is constant, and physiological differences between donors are minimized. In addition, isolating and propagating cell lines from primary RPE cell lines are expensive and time-consuming.
Competitive Advantage
At present, no other immortalized mouse RPE cell lines are available.
Applications
The cell line could be used to investigate mechanisms of and potential treatments for eye disease.
Patent Status
United States Patent application 12/318,152 was filed on December 22, 2008, and US 2009/0226955 A1 was published 10 September 2009.
Licensing Opportunity
We are seeking a licensing partnership for the manufacture, distribution, and marketing of this cell line.
