Could Nuvilex already know that the cells are not tumorigenic? From the 10-K: "Negotiations are underway between Nuvilex and that university for an exclusive, worldwide license to use these insulin-producing cells in combination with the Cell-in-a-Box ® technology in developing a product for the treatment of insulin-dependent diabetes. No assurance can be made that such a license will be entered into, however. Further, the license is contingent on the insulin-producing cells passing a tumorigenicity test that will be conducted by the University of Veterinary Medicine Vienna (“UVMV”) where Dr. Günzburg is a professor in the Department of Virology." Given that the license has already been attained, I can only assume that they already know the cells are not tumorigenic.
