Enhanced cell growth and viability in PAN RNA-expressing cell lines. Cells of the PAN RNA-expressing lines BJAB, Jurkat, and RPE were grown in culture for 5 to 8 days. Cell number and cell viability (MTT assays) were evaluated at 1, 4, 6, and 8 days (5 days for RPE). Each data point was generated from three separate replicates for each time point.
