The expression of ZsGreen was tested in 6 treated mice 136 to 142 days after cell injection, 5 of which presented 4,691±4,307 copies/104Abl1 (46.9% ZsGreen/Abl1) (~162-fold less than AML-succumbing mice, with a mean of 759,208±352,902 ZsGreen copies/104Abl1 in 89% of mice) (Fig 5E). The gene discussed is ABL1; the disease is acute myeloid leukemia.
