(e) Percentage of mitochondrialow cells in Syto16low cells. Liver erythroid cells (E18.5) were stained with Syto16 (DNA) and Mitotracker Deep Red. Representative dot plots of the mitochondrial content of Syto16low cells are demonstrated in Supplementary Fig. 5, the percentage of Syto16low cells without mitochondria was determined by gating the mitochondrialow fraction (mean±s.d., n=6). *P0.05 versus value of WT (ANOVA); #P0.05 versus value of Atg5−/− (ANOVA); 'NS' indicates not significant versus value of WT (ANOVA).
