(e-h) Impact of various drugs on mitochondrial clearance during in vitro differentiation. Differentiated cells from WT embryos were incubated with or without wortmannin (e), 3-methyladenine (3-MA) (f), rapamycin (g) or compound C (h) at the indicated concentrations and time periods. Percentage of mitochondrialow cells/Syto16low cells was measured by flow cytometry (mean±s.d., n=3). *P0.05 versus value of no drug (ANOVA).
