Additional file 4: Fig. S3. Effects of uridine’s feed time on cell growth and cell viability. a Viable cell density; b cell viability. Blank diamond control cultures; Blank triangle feed from day 1 to day 13; Blank square 6 feed from day 1 to day 6; Blank circle feed from day 7 to day 12. The total feed concentrations were 6 mM. The error bars indicate the standard deviations from three independent experiments.
