Becn1 is necessary for the clearance of autophagosomes and endosomes. Representative images from transmission electron microscopy of P13.5 large luteal cells from WT (A, C, and E) and Becn1 (fl/Δ) cKO (B, D, and F). An entire cell ultrastructure where lipid droplets mitochondria and nuclei are seen (A and B). High magnification images indicate mitochondria (Mt), lipid droplets (LD), multivesicular bodies (MVB), endosome (End), and autophagosomes (Aut) (C–F). Scale is indicated on the lower right corner of each image.
